Series 3700 System Switch/Multimeter Reference Manual Section 14: Verification
3700S-901-01 Rev. C / July 2008 14-7
To verify DC voltage accuracy:
NOTE 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.
1. Connect the Series 3700 HI and LO INPUT pins to the DC voltage calibrator
as shown in the "DC voltage verification" below.
2. Select the DC volts function.
3. Set the Series 3700 to the 100mV range.
4. If REL is needed, set the calibrator output to 0.00000mV DC and allow the
reading to settle.
5. Enable the Series 3700 REL mode.
6. Source positive and negative full-scale and half-scale voltages for each of
the ranges listed in the table below. For each voltage setting, be sure that
the reading is within stated limits.

Use the following values to verify the performance of the Series 3700. Actual
values depend on the published specifications (see Example reading limit
calculation (on page 14-4)).
