Accuracy of measurement
Measurement accuracy includes measurement stability, temperature coefficient, linearity,
repeatability and calibration interpolation error.
Examination of the accuracy of the instrument must be carried out under the following conditions:
a
．
Warm-up time: more than 30 minutes.
b
．
Warm-up time: more than 30 minutes.
c
．
Test cable length: 0m, 1M
d
．
Open circuit correctly and short circuit "0".after Preheating
e
．
The DC bias is in the "OFF" position, and the instrument range is at "AUTO" to select the
correct measurement range..
