2. Allow the instrument and cables to settle for 30 seconds.
3. On the calibrator, source 10 mV 1.0 kHz.
4. Enable the OPR key.
cal.ac.adjust steps 1 to 16 require the identified source values. If an alternate value is used,
incorrect accuracies will occur and possibly out of tolerance warning messages.
5. Ensure that the OPERATE display is illuminated.
6. Allow the calibrator and cable to properly settle.
AC voltage adjustment step 1: 10 mV at 1 kHz
Send the following command:
cal.adjust.ac(1)
AC voltage adjustment step 2: 100 mV at 1 kHz
1. On the calibrator, source 100 mV 1.0 kHz.
2. Allow the calibrator and cable to properly settle.
3. Send the following command:
cal.adjust.ac(2)
AC voltage adjustment step 3: 100 mV at 50 kHz
1. On the calibrator, source 100 mV 50 kHz and allow the calibrator and cable to properly settle.
2. Send the following command:
cal.adjust.ac(3)
AC voltage adjustment step 4: 1 V at 1.0 kHz
1. On the calibrator, source 1 V 1.0 kHz.
2. Allow the calibrator and cable to properly settle.
3. Send the following commands.
cal.adjust.ac(4)
AC voltage adjustment step 5: 1 V at 50 kHz
1. On the calibrator, source 1 V 50 kHz.
2. Allow the calibrator and cable to properly settle.
3. Send the following commands.
cal.adjust.ac(5)
AC voltage adjustment step 6: 10 V at 1.0 kHz
1. On the calibrator, source 10 V 1 kHz.
2. Allow the calibrator and cable to properly settle.
3. Send the following commands.
cal.adjust.ac(6)
AC voltage adjustment step 7: 10 V at 50 kHz
1. On the calibrator, source 10 V 50 kHz.
2. Allow the calibrator and cable to properly settle.
3. Send the following command:
