Measurement accuracy depends on measurement stability, temperature coefficient,
linearity,
repeatability and correction interpolation error.
Checking the measurement accuracy should be taken under the following circumstances:
a
.
Warm
‐
up time should be more than 30 minutes.
b
.
Correctly short the test cables, turn 0 ADJ to ON and perform short calibration by
pressing the touch key or 0 ADJ panel.
The correct short of the test cable is as follows:
