Current Test
Use the following procedure to verify proper operation of both the AC and DC mA measurement functions:
1.
Select DC mA, 200µA range.
2.
Connect the calibrator HI amps output to the V-
Ω terminal and the calibrator LO amps output to the
COM terminal.
3.
For each step in Table 6, select the listed range, program the calibrator for the corresponding UUT
input, and verify that the UUT display value lies within the indicated limits.
4.
Set the FUNCTION switch to the AC mA position and select the 20 mA range.
5.
Program the calibrator for a UUT input of 19.000 mA rms at a frequency of 100 Hz.
6.
Verify that the UUT display value lies between 18.890 and 19.110.

1.
Select k
Ω, 200Ω range.
2.
Connect the calibrator HI ohms output to the V-
Ω terminal and the calibrator LO ohms output to the
COM terminal.
