Step 6: Temperature Calibration
1. Connect the thermocouple calibrator to the Model
6517A EXT TEMP jack, as shown in Figure 2-6.
2. At the end of the coulombs calibration phase, the instru-
ment will prompt you for the first temperature calibra-
tion point:
CONNECT 0V/0°C
ENTER to continue; EXIT to abort

Charge calculated from: Q = CV, where C is capacitance standard
value, and V is the calibrator voltage. When using the Model 5156
Electrometer Calibration Standard, the Model 6517A automatically
calculates the charge from the actual capacitance value and the applied
calibrator voltage.

3. Set the thermocouple calibrator output to 0°C (0mV),
then press the Model 6517A ENTER key. During this
step, the instrument will display the following:
Performing 0 V Temp Calibration
4. Next, the instrument will prompt you for the 100°C
(4.095mV) calibration point:
CONNECT 4.095mV/100°C
5. Set the thermocouple calibrator output to 100°C, then
press the Model 6517A ENTER key. During this step,
the instrument will display the following message:
Performing 4.095mV Temp Calibration
Step 7: Voltage Source Calibration
WARNING
Hazardous voltages will be present
when performing the following steps.
Avoid touching terminals while per-
forming these procedures.
1. After temperature calibration has been completed, the
instrument will prompt you to connect the voltmeter to
the voltage source output jacks:
V-SOURCE CALIBRATION
Connect Vsource to voltmeter
2. Select the DCV function and the auto-range mode on the
DMM.
