2. Disconnect all test leads from the INPUT and AMPS
jacks, then press ENTER. During this calibration phase,
the instrument will display the following:
Performing Open Ckt Calibration
Step 8: AC self-calibration
1. After open circuit calibration, the instrument will dis-
play the following message:
AC CALIBRATION PHASE
2. Make sure all test leads are still disconnected from the
Model 2002 INPUT and SENSE jacks.
3. Press ENTER to perform AC calibration, which will
take about six minutes to complete. During AC calibra-
tion, the instrument will display the following:
Calibrating AC: Please wait
4. When AC calibration is finished, the instrument will dis-
play the following:
AC CAL COMPLETE
Step 9: Low-level calibration steps
1. Press ENTER. The instrument will display the follow-
ing to indicate the start of the low-level calibration
phase:
LOW-LEVEL CAL PHASE
NOTE
Use the exact calibration values shown
when performing the following steps.
2. Connect the calibrator to the INPUT terminals, as
shown in Figure 2-4.
3. Press ENTER. The instrument will display the
following:
Connect 20V @ 1kHz
4. Set the calibrator to output 20V AC at a frequency of
1kHz, then press ENTER. The instrument will display
the following:
Low-Level Cal - Step 1 of 13
5. Next, the instrument will prompt for a new calibration
signal:
Connect 20V @ 30kHz
6. Program the calibrator for an output voltage of 20V AC
at 30kHz, then press ENTER. The instrument will dis-
play the following while calibrating this step:
Low-Level Cal - Step 2 of 13
7. The Model 2002 will then display:
Connect 200V @ 1kHz
8. Set the calibrator output to 200V AC at a frequency of
1kHz, then press ENTER. The Model 2002 will display
the following message:
Low-Level Cal - Step 3 of 13
9. When finished with this step, the Model 2002 will
display:
Connect 200V @ 30kHz
