Measurement Accuracy
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 and reset the instrument by pressing the REL button on the
front panel.
The correct shorting of the test cable is done as follows:
