2.6.5 Measurement Accuracy Test
Procedure
1. Turn the power ON again, then allow the instrument to warm up for at least 10 minutes.
2. Input DC voltage and resistance to channel 2 of the MX110-V4R-M06, then
confirm that the specifications are met at each range.
• Settings on Module under Test: Set the range and measurement interval
according to the table.
Measurement Interval Duration
100 ms 5 seconds or more
500 ms 10 seconds or more
• Test the module’s input voltage while measuring the DC voltage generator’s
output on a digital multimeter.
• If calibration was performed, power cycle the instrument before the test.
Confirm that the measured results are within the judgement criteria range in the
chart below.
