Testing the DC and AC Current Function
1.
Set the UUT rotary switch to amps.
2.
Set the output of the current calibrator to standby and connect it to the 40 mA and COM input terminals
of the UUT.
3.
Set the current calibrator to the output shown in Table 10. Verify that the UUT display/reading is within
the limits shown
