2.5.5 Measurement Accuracy Test

Procedure

Turn the power ON then OFF.

Turn the power ON again, then allow the instrument to warm up for at least 10

minutes.

Adjust so that the wires connected to the A, B, and b terminals have the same

resistance value.

Set channel 2 as the measurement channel, and the measurement interval and

duration as follows:

Measurement Interval Duration

100 ms 5 seconds or more

500 ms 10 seconds or more

Confirm that the measured results are within the judgment criteria range in the

chart below.
