1-8 Performance Verification
Model 2700 verification
Perform these tests to verify accuracy using the Model 2700 front panel terminals.
Verifying DC voltage
Check DC voltage accuracy by applying accurate voltages from the DC voltage calibrator to
the Model 2700 INPUT jacks and verifying that the displayed readings fall within specified
limits.
CAUTION
Do not exceed 1000V peak between front terminals INPUT HI and
INPUT LO because instrument damage may occur.
Follow these steps to verify DC voltage accuracy:
1. Connect the Model 2700 HI and LO INPUT jacks to the DC voltage calibrator as
shown in Figure 1-1. Make sure the INPUTS switch is set to the FRONT position.
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 calibra-
tor’s output LO terminal.

2. Select the DC volts function by pressing the
DCV
key, and set the Model 2700 to the
100mV range.
3. Set the calibrator output to 0.00000mV DC, and allow the reading to settle.
4. Enable the Model 2700 REL mode. Leave REL enabled for the remainder of the DC
volts verification tests.
