A pocket scale for electronics components should be selected by balancing two specifications:
capacity and resolution.
Capacity tells you:
the maximum total physical load the scale is designed to support.
Resolution—also commonly called readability—tells you:
the smallest increment displayed by the scale.
For example:
500g × 0.01g
means the scale has:
-
500g maximum nominal capacity
-
0.01g displayed increments
Meanwhile:
50g × 0.001g
means:
-
50g maximum nominal capacity
-
0.001g displayed increments
The second scale displays measurements in finer increments.
But it has only:
one-tenth the capacity.
That tradeoff matters enormously when weighing electronics.
Electronic components can range from extremely lightweight:
-
SMD resistors
-
Capacitors
-
Diodes
-
LEDs
-
Transistors
-
ICs
-
Tiny screws
to substantially heavier:
-
Connectors
-
Relays
-
Motors
-
Heat sinks
-
Development boards
-
PCB assemblies
-
Component batches
For many general electronics applications:
500g × 0.01g
is an especially versatile pocket-scale configuration.
For extremely lightweight individual components:
20–100g × 0.001g
may provide more useful displayed detail.
The right choice depends on:
what you actually weigh.
Quick Answer: What Capacity and Resolution Do You Need?
| Electronics Application | Capacity to Consider | Resolution/Readability to Consider |
|---|---|---|
| Tiny SMD components | 20–100g | 0.001g |
| Individual resistors | 20–100g | 0.001g |
| Small capacitors | 20–100g | 0.001g |
| Diodes | 20–100g | 0.001g |
| LEDs | 20–100g | 0.001–0.01g |
| Transistors | 20–100g | 0.001–0.01g |
| Small ICs | 20–100g | 0.001g |
| Larger ICs | 100–500g | 0.01g |
| Sensors | 100–500g | 0.01g |
| Connectors | 100–500g | 0.01g |
| Relays | 100–500g | 0.01g |
| Small heat sinks | 500g | 0.01g |
| Small PCB assemblies | 500g | 0.01g |
| Component batches | 500g+ | 0.01–0.1g |
| Large PCB assemblies | 500g+ | 0.01–0.1g |
These are practical starting points rather than universal requirements.
Your actual application should determine the final specification.
What Does Capacity Mean on a Pocket Scale?
Capacity is:
the maximum physical load the weighing system is designed to support.
Common pocket-scale capacities include:
-
20g
-
30g
-
50g
-
100g
-
200g
-
500g
Higher-capacity scales are also available, but as capacity increases, the scale may become:
larger
and may no longer fit the traditional:
pocket-scale format.
What Does Resolution Mean on a Pocket Scale?
Resolution or readability describes:
the smallest increment shown on the display.
Examples:
0.1g
The display changes in:
one-tenth-of-a-gram increments.
0.01g
The display changes in:
one-hundredth-of-a-gram increments.
0.001g
The display changes in:
one-thousandth-of-a-gram increments.
Because:
0.001g = 1 milligram,
scales with 0.001g readability are commonly called:
milligram scales.
For a deeper explanation of capacity and readability, see AWS's guide to what 500g × 0.01g means on a digital scale.
Capacity vs. Resolution: The Core Tradeoff
Suppose you are comparing:
Scale A: 50g × 0.001g
and:
Scale B: 500g × 0.01g.
Scale A provides:
10× finer displayed increments.
Scale B provides:
10× greater maximum capacity.
Which is better?
Neither universally.
The answer depends on:
the electronics components you need to weigh.
Example: Tiny SMD Component
Suppose a component weighs approximately:
0.026g.
A:
0.001g scale
may display:
0.026g.
A:
0.01g scale
cannot provide the same displayed detail.
For this application:
fine readability may matter more than high capacity.
Example: PCB Assembly
Suppose a completed board weighs:
286.34g.
A:
50g × 0.001g
scale cannot support it.
A:
500g × 0.01g
scale can.
For this application:
capacity matters more than the additional decimal place.
20g × 0.001g Pocket Scales
A:
20g × 0.001g
scale provides:
very fine readability
with:
very limited capacity.
This configuration can be appropriate for:
-
Tiny SMD components
-
Small resistors
-
Lightweight capacitors
-
Tiny diodes
-
Small screws
-
Lightweight ICs
The main limitation is:
capacity.
The Problem With 20g Capacity
Suppose:
Component = 8g
Tray = 13g
Total physical load:
21g
A:
20g scale
cannot support the complete load.
Even though:
the component itself weighs only 8g.
50g × 0.001g Pocket Scales
A:
50g × 0.001g
configuration offers:
milligram readability
with:
more practical capacity.
It can be useful for:
-
SMD components
-
Resistors
-
Capacitors
-
Diodes
-
LEDs
-
Transistors
-
ICs
-
Small connectors
-
Screws
-
Washers
-
Small component groups
For many fine electronics applications:
50g provides substantially more flexibility than:
20g.
50g Capacity Example
Suppose:
IC = 12g
Tray = 8g
Total:
20g
A:
50g scale
provides:
30g of nominal remaining capacity.
That is far more comfortable than:
a 20g scale operating at its limit.
100g × 0.001g Pocket Scales
A:
100g × 0.001g
configuration can provide an attractive middle ground.
You retain:
milligram readability
while gaining:
more capacity for containers, larger components and small batches.
This can be particularly useful for:
-
Larger IC packages
-
Connectors
-
Component groups
-
Small hardware batches
-
Heavier trays
-
Small modules
AWS includes 20g, 30g, 50g and 100g options among the 0.001g models compared in its Best Milligram Scales guide.
500g × 0.01g Pocket Scales
For general electronics work:
500g × 0.01g
is one of the most versatile pocket-scale specifications.
It provides enough capacity for many:
-
Connectors
-
Sensors
-
Relays
-
Switches
-
Small motors
-
Heat sinks
-
PCB assemblies
-
Hardware batches
while retaining:
hundredth-of-a-gram readability.
Why 500g Capacity Is Useful
Consider a mixed electronics workflow:
Resistor = 0.48g
IC = 4.25g
Connector = 16.38g
Sensor module = 24.72g
Relay = 38.46g
Heat sink = 92.35g
PCB assembly = 284.62g
A:
500g scale
can support all of these examples.
A:
50g scale
cannot.
Why 0.01g Is Often Enough
For an object weighing:
284.62g,
an additional decimal place usually provides much less practical value than:
sufficient capacity.
Likewise, a connector weighing:
18.47g
can already be documented with:
hundredth-of-a-gram displayed increments.
Do not automatically assume:
0.001g is better.
Resolution Is Not the Same as Accuracy
This is critical.
A scale displaying:
0.001g
does not automatically guarantee:
±0.001g accuracy.
Resolution/readability tells you:
the smallest displayed increment.
Measurement performance can also depend on:
-
Repeatability
-
Calibration
-
Linearity
-
Minimum usable load
-
Temperature
-
Airflow
-
Vibration
-
Load position
-
Electrical conditions
Do Not Choose by Decimal Places Alone
Compare:
50g × 0.001g
with:
500g × 0.01g.
The first scale has:
more displayed digits.
But if your object weighs:
175g,
those digits are irrelevant because:
the scale cannot support the object.
Always determine:
capacity first enough to support the load, then sufficient readability for the measurement.
Calculate Your Maximum Complete Load
Before buying a pocket scale, calculate:
component + tray + container + holder = total physical load.
Example:
PCB = 375g
Tray = 48g
Total:
423g
A:
500g scale
can nominally support the load.
A:
100g scale
cannot.
Tare Does Not Restore Capacity
Suppose:
Scale capacity = 50g
Tray = 15g.
Place the tray on the scale.
Display:
15.000g.
Press:
TARE.
Display:
0.000g.
You have not created:
another 50g of capacity.
The tray is still applying:
15g
of physical load.
Approximate remaining physical capacity:
35g.
Why Tare Matters for Electronics
Tare is still extremely useful.
Tiny electronic components can:
-
Roll
-
Slide
-
Fall
-
Become difficult to retrieve
A tray helps contain:
small parts.
Use tare to remove:
the tray's displayed mass.
Leave Capacity Headroom
Do not choose a pocket scale where your normal load constantly sits:
near maximum capacity.
Suppose:
Board = 440g
Tray = 42g
Total =
482g.
A:
500g scale
technically provides enough nominal capacity.
But there is:
very little headroom.
If this represents your normal workload:
consider a higher-capacity scale.
Best Pocket Scale Capacity for SMD Components
For extremely lightweight SMD components:
20–100g
may be sufficient.
The more important specification may be:
0.001g readability.
However, consider:
tray weight
before choosing:
20g or 30g capacity.
Best Pocket Scale for Resistors
For individual lightweight resistors:
0.001g readability
may be useful.
Possible capacity:
20–100g.
For resistor batches:
higher capacity becomes more important.
Best Pocket Scale for Capacitors
Capacitors vary enormously.
For tiny individual capacitors:
20–100g × 0.001g
may be appropriate.
For larger capacitors or batches:
500g × 0.01g
may provide more useful flexibility.
Best Pocket Scale for Diodes
Tiny individual diodes can be:
well suited to milligram scales.
Consider:
50–100g × 0.001g
when you also need:
room for a tray.
Best Pocket Scale for LEDs
For tiny LEDs:
0.001g may be useful.
For:
larger LED modules,
0.01g may provide sufficient resolution with:
greater capacity.
Best Pocket Scale for Transistors
Small individual transistors may fit comfortably within:
50–100g capacity.
Choose:
0.001g
only when the additional displayed detail is:
actually useful.
Best Pocket Scale for ICs
Integrated circuits range from:
tiny surface-mount packages
to much larger devices.
For tiny ICs:
50–100g × 0.001g
may be useful.
For larger ICs and groups:
500g × 0.01g
provides more flexibility.
Best Pocket Scale for Sensors
Many complete sensor modules do not require:
milligram readability.
A:
500g × 0.01g
scale provides substantial capacity while retaining:
fine displayed increments.
Best Pocket Scale for Connectors
Connectors can be:
significantly heavier than passive components.
For individual connectors and connector batches:
500g × 0.01g
is often more practical than:
a low-capacity milligram scale.
Best Pocket Scale for Relays
Relays generally do not require:
0.001g resolution.
Prioritize:
capacity, platform size and repeatability.
Best Pocket Scale for Small Heat Sinks
Heat sinks can quickly consume:
pocket-scale capacity.
A:
500g × 0.01g
scale may work well for:
small heat sinks.
For larger cooling hardware:
use a higher-capacity scale.
Best Pocket Scale for Circuit Boards
For small PCB assemblies:
500g × 0.01g
is a practical starting point.
But check:
both weight and dimensions.
A board can be:
under 500g
while still being:
too large for the platform.
Platform Size Matters
Capacity answers:
Can the scale support the weight?
Platform size answers:
Can the object physically sit on the scale correctly?
Both matter.
Do Not Let the PCB Rest on the Workbench
Suppose:
half the PCB rests on the scale
and another section touches:
the table.
The scale is not supporting:
the complete physical load.
That can compromise:
the measurement.
Use an appropriate weighing arrangement where:
the entire load is supported.
A Practical AWS Pocket Scale for Electronics Components
For general electronics applications, the AWS SC501g Precision Digital Pocket Scale provides:
500g capacity × 0.01g readability.
Useful features include:
-
3.9 × 3.7-inch stainless-steel platform
-
Backlit LCD
-
Tare
-
Two expansion trays
-
Multiple weighing units
-
Compact design
-
Battery operation
This combination is particularly useful for:
-
Sensors
-
Connectors
-
Relays
-
Switches
-
ICs
-
Small heat sinks
-
Small PCB assemblies
-
Component batches
-
Electronics hardware
Why the SC501g Works as a General-Purpose Electronics Scale
Its biggest advantage is:
working range.
A 50g milligram scale may provide:
finer displayed increments.
But a 500g pocket scale can accommodate:
far more types of electronics components.
For a technician or hobbyist who wants:
one versatile compact scale,
500g × 0.01g is often a more practical specification.
When a Milligram Scale Is Better
Choose:
0.001g readability
when your actual work requires:
fine comparison of extremely lightweight components.
Examples:
-
SMD parts
-
Tiny resistors
-
Small capacitors
-
Tiny diodes
-
Small ICs
-
Miniature screws
For these applications:
20–100g capacity
may be sufficient.
When a Pocket Scale Is the Wrong Tool
Do not force a pocket scale into an application it was not designed to handle.
Choose a larger scale when:
-
Your PCB exceeds capacity.
-
Your board is too large for the platform.
-
Your electronics assembly exceeds 500g.
-
You weigh large battery packs.
-
You weigh large motors.
-
You weigh heavy heat sinks.
-
Your component batches exceed capacity.
-
Your normal load sits close to maximum capacity.
Pocket Scale vs. Bench Scale for Electronics
A pocket scale prioritizes:
-
Portability
-
Compact dimensions
-
Fine readability
-
Convenient storage
A larger bench scale generally provides:
-
Greater capacity
-
Larger platform
-
Better support for larger PCB assemblies
-
Better support for bulk inventory
Neither format is automatically:
better.
Choose according to:
the physical objects being weighed.
Should You Choose 0.001g or 0.01g?
Ask:
What is the smallest weight difference that matters to my application?
If you need to compare:
very lightweight individual components,
0.001g may be appropriate.
If you primarily weigh:
connectors, modules, PCBs and batches,
0.01g is often more practical.
0.001g vs. 0.01g Comparison
| Feature | 0.001g Scale | 0.01g Scale |
|---|---|---|
| Display increment | 1 mg | 10 mg |
| Typical strength | Tiny components | General electronics |
| Typical capacity | Lower | Higher |
| SMD components | Excellent use case | May lack desired detail |
| ICs | Excellent for small ICs | Good for larger ICs |
| Connectors | Limited by capacity | Strong use case |
| PCB assemblies | Usually impractical | Stronger option |
| Batches | Limited | More practical |
| Environmental sensitivity | Greater concern | Less demanding |
| Portability | Often excellent | Excellent |
Why Environment Matters More at 0.001g
As displayed increments become finer:
environmental influences become increasingly important.
Potential contributors include:
-
Airflow
-
Vibration
-
Temperature changes
-
Static
-
Off-center loading
-
Electrical noise
-
Indicator drift
For milligram work:
your weighing environment matters almost as much as:
the scale specification.
Avoid Direct Airflow
Do not place a milligram scale directly beside:
-
Cooling fan
-
HVAC vent
-
Open window
-
Bench fan
Air movement can contribute to:
unstable measurements.
Reduce Vibration
Electronics benches can contain:
-
Power tools
-
Cooling systems
-
Speakers
-
Motors
-
Test equipment
Use:
a rigid, stable weighing surface.
Consider Draft Protection
For extremely lightweight components:
draft protection can help create:
a more stable weighing environment.
This is particularly useful for:
0.001g measurements.
Consider Static
Electronics components may require:
ESD precautions.
Very lightweight weighing can also be affected by:
electrostatic effects.
Follow the appropriate:
ESD handling procedures
for your components.
Do not assume a standard pocket scale is automatically:
ESD-safe.
Calibration Matters
A scale's capacity and resolution do not eliminate the need for:
proper calibration.
Follow:
the calibration procedure for the exact scale model.
Use:
the specified reference mass.
Do not improvise with:
-
Coins
-
Batteries
-
Resistors
-
Connectors
-
Screws
-
Other electronics parts
as calibration standards.
NIST's guidance on balance and scale calibration and uncertainties emphasizes proper calibration procedures, appropriate reference standards and understanding potential measurement uncertainty.
Calibration Requirements Vary by Scale
A:
20g milligram scale
may use a different calibration mass than:
a 500g pocket scale.
For example, the SC501g specifies:
500g calibration weight, not included.
Check the model specifications before purchasing so you know:
what calibration equipment is required.
Capacity and Resolution Do Not Determine Everything
When comparing pocket scales, also consider:
-
Repeatability
-
Minimum usable load
-
Platform dimensions
-
Tare
-
Expansion trays
-
Piece counting
-
Display visibility
-
Battery operation
-
Protective cover
-
Calibration procedure
-
Operating environment
Repeatability Matters
A scale with:
0.001g resolution
is less useful if the same component repeatedly produces:
widely different readings.
For fine electronics work:
repeatability matters.
Simple Repeatability Test
Weigh the same component several times.
Example:
1.247g
1.247g
1.248g
1.247g
1.247g
Compare:
the results.
For demanding measurement work, use procedures appropriate to:
your actual quality requirements.
Minimum Usable Load Matters
A scale displaying:
0.001g
does not automatically mean:
0.001g is an appropriate working load.
Where available:
review manufacturer specifications for:
-
Minimum load
-
Accuracy
-
Repeatability
especially when weighing:
extremely lightweight components.
Piece Counting for Electronics Components
Some scales can estimate:
piece quantity
from weight.
This can be useful for:
-
Screws
-
Washers
-
Resistors
-
Connectors
-
Similar small components
But the pieces should have:
reasonably consistent individual weights.
Capacity Matters for Piece Counting
Suppose:
one screw = 0.35g
500 screws ≈ 175g.
A:
50g scale
cannot handle:
the entire batch.
A:
500g scale
can provide:
far more useful capacity.
This illustrates why inventory applications often benefit from:
higher capacity.
One Pocket Scale or Two?
For many users:
one scale is enough.
If your workflow is primarily:
connectors, modules, small PCBs and component batches,
choose:
500g × 0.01g.
If your workflow is almost entirely:
tiny individual components,
consider:
50–100g × 0.001g.
When Two Scales Make Sense
Suppose your electronics work includes:
SMD component = 0.024g
Small IC = 1.85g
Sensor = 14.60g
Connector = 28.45g
Heat sink = 96.80g
PCB assembly = 345.25g
A practical setup is:
Fine Component Scale
50–100g × 0.001g
Use for:
-
SMD components
-
Resistors
-
Capacitors
-
Diodes
-
Tiny ICs
-
Small screws
General Electronics Pocket Scale
500g × 0.01g
Use for:
-
Sensors
-
Connectors
-
Relays
-
Heat sinks
-
PCB assemblies
-
Component batches
This gives you:
fine readability where it matters
without sacrificing:
capacity for larger components.
Capacity Selection Guide
Choose 20g When:
-
Everything you weigh is extremely lightweight.
-
You require 0.001g readability.
-
Your tray is extremely light.
-
You never approach 20g total load.
Choose 50g When:
-
You primarily weigh small components.
-
You require 0.001g.
-
You want more tray headroom than a 20g scale provides.
Choose 100g When:
-
You require 0.001g.
-
You weigh larger components or groups.
-
50g feels restrictive.
Choose 500g When:
-
You want one general-purpose electronics pocket scale.
-
You weigh connectors.
-
You weigh modules.
-
You weigh small heat sinks.
-
You weigh PCB assemblies.
-
You weigh component batches.
-
0.01g readability is sufficient.
Choose More Than 500g When:
-
Your boards are heavy.
-
You weigh battery packs.
-
You weigh larger motors.
-
You weigh large heat sinks.
-
You weigh bulk component inventory.
-
Your normal complete load exceeds 500g.
Pocket Scale Selection Examples
Example 1: SMD Repair Technician
Typical items:
0.02–5g.
Priority:
fine measurement.
Consider:
50g × 0.001g.
Example 2: General Electronics Hobbyist
Typical items:
1–350g.
Priority:
versatility.
Consider:
500g × 0.01g.
Example 3: Component Seller
Typical items:
individual parts plus batches.
Priority:
fine measurement + inventory.
Consider:
0.001g scale + higher-capacity scale.
Example 4: PCB Prototype Developer
Typical boards:
50–450g.
Priority:
prototype weight comparison.
Consider:
500g × 0.01g
provided the platform accommodates the board.
Example 5: Large Electronics Assemblies
Typical load:
500g–3kg.
Priority:
capacity.
A pocket scale is probably:
not the correct primary tool.
Use:
a higher-capacity bench scale.
Can Weight Identify an Electronics Component?
No.
Weight cannot independently determine:
-
Part number
-
Resistance
-
Capacitance
-
Voltage rating
-
Manufacturer
-
Function
-
Authenticity
Use:
markings, datasheets and appropriate testing.
Can Weight Determine Whether a Component Works?
No.
A component can have:
the expected mass
and still be:
electrically defective.
A scale complements:
electronics testing.
It does not replace it.
Can Weight Detect Counterfeit Electronics?
Not by itself.
Weight can provide:
one comparison characteristic.
Authentication may require:
additional inspection, documentation and specialized testing.
Commercial Weighing Considerations
If a scale is used only for:
internal electronics inventory, comparison or prototype work,
requirements differ from:
regulated commercial weighing.
NIST's 2026 Handbook 44 covers specifications, tolerances and other technical requirements used for many commercial weighing and measuring devices.
Do not assume:
a consumer pocket scale is automatically legal for trade.
Common Mistakes When Choosing an Electronics Pocket Scale
Buying the Scale With the Most Decimal Places
More decimal places do not automatically mean:
better for your application.
Ignoring Capacity
A scale that cannot support the object is:
the wrong scale.
Forgetting the Tray
Tray mass contributes to:
total physical load.
Assuming Tare Restores Capacity
It does not.
Choosing 20g When You Really Need 50g
Leave:
usable headroom.
Choosing 50g When You Weigh PCBs
Consider:
500g or more.
Buying 500g When Your Assemblies Weigh 800g
Choose:
higher capacity.
Ignoring Platform Size
Weight capacity does not guarantee:
physical fit.
Confusing Resolution With Accuracy
They are:
not interchangeable.
Ignoring Repeatability
Consistent measurements matter.
Ignoring Calibration
Follow:
the correct model procedure.
Ignoring Airflow
Milligram measurements can be affected by:
drafts.
Ignoring Vibration
Use:
a stable surface.
Assuming a Standard Scale Is ESD-Safe
Verify:
your actual ESD requirements.

Is 0.001g better than 0.01g?
Not automatically.
0.001g provides:
finer displayed increments.
0.01g scales often provide:
greater capacity.
What does 500g × 0.01g mean?
It means:
500g maximum nominal capacity
and:
0.01g displayed increments.
What does 50g × 0.001g mean?
It means:
50g maximum nominal capacity
and:
0.001g displayed increments.
Is 0.001g the same as accuracy?
No.
It describes:
resolution/readability.
Is 500g enough for circuit boards?
For many small PCBs:
yes.
But weigh or estimate:
your actual board.
Also check:
platform size.
What scale should I use for SMD components?
Consider:
50–100g × 0.001g
when milligram-level displayed increments are useful.
What scale should I use for resistors?
For individual lightweight resistors:
0.001g may be useful.
For batches:
higher capacity may matter more.
What scale should I use for ICs?
For tiny ICs:
0.001g may be useful.
For larger ICs and batches:
0.01g can be more practical.
What scale should I use for PCBs?
For small assembled PCBs:
500g × 0.01g
is a practical starting point.
Does a tray count toward capacity?
Yes.
The tray remains:
physical load.
Does tare give me more capacity?
No.
Tare changes:
the displayed zero.
Can I use a pocket scale for component counting?
Some scales provide:
piece-counting functionality.
The components should have:
consistent individual weights.
Why does my 0.001g scale fluctuate?
Possible contributors include:
-
Airflow
-
Vibration
-
Static
-
Temperature changes
-
Unstable surfaces
-
Off-center loading
Can a pocket scale identify components?
No.
Weight alone cannot determine:
electrical specifications or identity.
Should I buy one or two scales?
If your electronics work ranges from:
tiny SMD components
to:
300–500g PCB assemblies,
two scales can provide better coverage.
Final Verdict: What Capacity and Resolution Do You Need?
The best pocket scale for electronics components depends on two questions:
How light is the smallest component you need to measure meaningfully?
and:
How heavy is the largest complete load you need to support?
For extremely lightweight:
-
SMD components
-
Resistors
-
Capacitors
-
Diodes
-
Tiny ICs
-
Screws
-
Small hardware
consider:
50–100g × 0.001g
when milligram-level resolution is genuinely useful.
For broader electronics work involving:
-
Sensors
-
Connectors
-
Relays
-
Switches
-
Heat sinks
-
PCB assemblies
-
Component batches
consider:
500g × 0.01g.
For many users, 500g × 0.01g provides the strongest balance between:
fine readability and practical capacity.
The AWS SC501g is a strong general-purpose example, providing:
-
500g capacity
-
0.01g readability
-
3.9 × 3.7-inch platform
-
Stainless-steel weighing surface
-
Tare
-
Two expansion trays
-
Backlit LCD
-
Battery operation
For users working at both extremes, a practical two-scale setup is:
50–100g × 0.001g for tiny electronics components
plus:
500g × 0.01g for larger components and PCB assemblies.
If your normal load exceeds:
500g,
move beyond the pocket-scale format and choose:
a higher-capacity scale.
Whatever capacity you select, remember:
resolution is not automatically accuracy.
The tray counts toward:
total physical capacity.
Tare does not:
restore capacity.
Platform size matters in addition to:
weight capacity.
And at 0.001g readability, factors such as:
airflow, vibration, static, temperature and load placement
become increasingly important.
Choose the scale based on:
your real electronics workflow—not simply the highest number of decimal places.
