AC Volts Calibration (AUX Output)
To calibrate the auxiliary ac voltage function, use the same procedure as shown
for the normal ac voltage output, but use the AUX HI and LO terminals instead on
the UUT. Table 39 shows the calibration steps for AUX ac volts.
Table 39. Calibration Steps for AUX AC Volts
Steps
Output (AUX)
Amplitude Frequency
1 300.00 mV 55 Hz
2 300.00 mV 1 kHz
3 3.0000 V 55 Hz
4 3.0000 V 1 kHz
5 5.0000 V 55 Hz
6 5.000 V 1 kHz
Resistance Calibration
The equipment shown in Table 40 is necessary for calibration of the resistance
function.
Table 40. Test Equipment Required for Resistance Calibration
Quantity Manufacturer Model Equipment
1 Fluke 8508A DMM
To calibrate the resistance function:
1. Use the Fluke 8508A DMM for each measurement.
2. Make sure the UUT is in Standby.
3. Follow the prompt on the Control Display to connect the DMM to the UUT for
4-wire ohms measurement as shown in Figure 15.
4. Push the GO ON softkey and wait for the internal calibration steps to
complete.
5. When the internal calibration steps are done, measure and type in the values
into the UUT for calibration steps 1 through 12 in Table 41 as prompted.
6. Connect the UUT to the DMM in a 2-wire ohms configuration as shown in
Figure 16.
7. Measure and type in the values into the UUT for calibration steps 13 through
18 in Table 41 as prompted.
8. Make sure the UUT is in Standby and disconnect the test equipment.
