AC Voltage Test (Option -09 Only)
The following procedure may be used to verify the accuracy of the VAC function:
1.
Ensure the 8842A is on and warmed up for at least 1 hour.
2.
Select the VAC function and the slow (S) reading rate.
3.
Connect the AC Calibrator to provide a voltage input to the HI and LO INPUT
terminals.

4.
(Low- and Mid-Frequency Test.) For each step in Table 6-3, select the indicated
range, set the AC Calibrator for the specified input, and verify that the displayed
reading is within the limits shown for each reading rate.
