This section will explain the meter’s accuracy, measurement tolerance and how
to test the meter’s performance. It includes:
Accuracy
Factors that decide accuracy
The meters’ accuracy is affected by the tolerances from measurement stability,
temperature variation, circuit linearity and the measurement repeatability.
The meter’s accuracy verification needs to be done under the following
circumstances:
Warming up time: ≥ 30 minutes.
Perform Open/Short calibration correctly after warming up.
Set the meter to auto-ranging mode.
