4 Calibration, Verification, and Service
RMS Current Measurement Accuracy
This test verifies the measurement accuracy of the rms current readback.
Step Action
1
Turn off the UUT and connect the appropriate load resistor, current
shunt and DMM as shown above.
2
Turn on the UUT. Program the output to RANGE 155 V,VOLT 80, FREQ
60.
3
Record DMM reading and calculate rms current
4
Program output to RANGE 155 V,VOLT 80, FREQ 500.
5
Record DMM reading and calculate rms current.
6
Turn on the UUT. Program the output to RANGE 310 V,VOLT 160, FREQ
60.
7
Record DMM reading and calculate rms current
8
Turn on the UUT. Program the output to RANGE 310 V,VOLT 160, FREQ
500.
9
Record DMM reading and calculate rms current.
