Linear Voltage Test
Use the following procedure to verify the proper operation of both the AC and DC V functions:
1.
Select DC V, 200mV range.
2.
Connect the calibrator HI volts output to the V-
Ω terminal and the calibrator LO volts output to the
COM terminal.
3.
For each step of Table 5, set the ACV/DCV switch to the indicated position, select the listed range,
program the calibrator for the corresponding input to the UUT, and verify that the UUT display value
lies within the indicated limits.
