2. Install the Model 7700 in Slot 1 of the Model 2700, then turn on the power, and allow
the unit to warm up for two hours before proceeding. Be sure the front panel INPUTS
switch is set to the REAR position.
3. Select the DC volts function by pressing the DCV key, and set the Model 2700 to the
100mV range. Close Channel 1 by pressing the CLOSE key and then keying in 101.
4. Set the calibrator output to 0.00000mV DC, and allow the reading to settle.
5. Enable the Model 2700 REL mode. Leave REL enabled for the remainder of the DC
volts verification tests.
6. Source positive and negative and full-scale voltages for each of the ranges listed in
Table 1-9. For each voltage setting, be sure that the reading is within stated limits.
7. Press the OPEN key to open Channel 1.
