Verifying AC voltage

Check AC voltage accuracy by applying accurate voltages from the AC voltage calibrator to the
Series 3700 analog backplane connector and verify that the displayed readings fall within
specified limits.
CAUTION
To verify AC voltage accuracy:
NOTE
1. Connect the Series 3700 HI and LO INPUT pins to the DC voltage calibrator as shown in the
ACV verification diagram.
2. Select the AC volts function.
3. Set the Series 3700 to the 100mV range; make sure that REL is disabled.
4. Source AC voltages for each of the frequencies and ranges summarized in the ACV
verification data table. For each setting, be sure that the reading is within stated limits.

Do not exceed 300V peak between INPUT HI and INPUT LO, or 8 × 10
input, because instrument damage may occur.
Use shielded, low-thermal connections when testing the 100mV and 1V ranges to
avoid errors caused by noise or thermal effects. Connect the shield to the calibrator's
output LO terminal.
