2.5.5 Measurement Accuracy Test
Procedure
1. Turn the power ON then OFF.
2. Turn the power ON again, then allow the instrument to warm up for at least 10
minutes.
3. 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
4. Confirm that the measured results are within the judgment criteria range in the
chart below.
