Not every tabletop scale has the same level of precision.
Readability Is Not the Same as Accuracy
A scale may display weight in 1g, 2g, 5g or 10g increments depending on the model.
That display resolution does not automatically mean the scale is accurate to exactly that amount in every situation.
What Can Affect Accuracy?
Factors include:
Calibration
Load-cell condition
Platform stability
Overloading
Mechanical interference
Uneven surfaces
Temperature
Vibration
Power problems
Incorrect setup
Signs of Accuracy Problems
Watch for:
Different readings for the same item
Scale not returning to zero
Weight changing while the load is still
Incorrect known-weight results
Unusual error messages
Calibration
Calibration can be used to verify and adjust weighing performance.
Some Uganda service providers offer tabletop scale calibration and maintenance services.
When Should You Call a Technician?
If the scale remains inaccurate after checking the platform, zero and operating conditions, it may need professional inspection.
A technician can check the load cell, electronics, wiring and calibration.
