5.  in the display shows the CAL mode is set and the Meter is at the first calibration
adjustment step.
WCaution
To prevent damage to the Meter, make sure the calibrator is in
standby before you change its parameters, or change the
function on the Meter.
6. Set the calibrator to the parameters shown in the Input Value column of Table 6 for
the calibration step shown in the display.
Note
You can push  to show the necessary input signal level and G to
show the necessary input signal frequency for the calibration step.
8. Turn on the output signal on the calibrator.
9. Push D to complete the step and move to the subsequent step.
If the step shown in the display moves to the subsequent step, the adjustment was
successful. If the Meter gives two beeps and does not move to the subsequent step,
then the adjustment was not successful. Make sure the calibrator is set correctly and
push D again. If the calibrator output is correct, then it is necessary to repair the
Meter.
Note
If the calibration adjustment is not completed correctly, the Meter will not
operate correctly.
10. Put the calibrator in standby.
11. Do steps 6 through 10 for each calibration step in Table 6.
12. After you complete the last adjustment step,  shows in the display. Push D to
complete the calibration adjustment procedure and store the calibration constants in
the Meter.
