6.5 AC Voltage Test
The following procedure may be used to verify the accuracy of the ACV function:
1. If you have not done so, install the SMU2060/64 DMM and place the covers back on to the computer. Ensure
that the computer has been on for at least one-half hour, with the covers on, before conducting this test.
2. Apply the following AC voltages to the V,  + & - terminals. Check to see that the displayed reading on the
DMM is within the indicated readings range.
