Meter Keys Used In The Calibration Steps; Calibration Adjustment - Fluke 1587 Calibration Manual

Meter Keys Used in the Calibration Steps

The Meter keys behave as follows when performing the Calibration Adjustment
Procedure. This may be of help determining why a calibration step is not accepted
and for determining the input value without referring to Table 6.
Press and hold to show the measured value. The measurement value is not
H
calibrated so it may not match the input value. This is normal.
Press and hold to display the required input amplitude.
t
Press and hold to display the frequency of the required input.
h
Store the calibration value and advance to the next step. This key is also
G
used to exit the calibration mode after the calibration-adjustment sequence
is complete.

Calibration Adjustment

Use the following steps to make calibration adjustments to the UUT. Complete the
adjustment procedure before turning the UUT off; otherwise, the new calibration
constants will not be saved.
1. While holding down H, turn the rotary switch from OFF to B. The UUT
displays Z CAL.
2. Press h once to see the calibration counter, e.g., n0001.
3. Press h again to start the password entry. The UUT displays ?. ? . ? . ? .
4. Press four keys to enter the password.
5. Press h to go to the first calibration step. The UUT displays C-01 if the
password is correct. If the password is not correct, the UUT emits a double beep,
displays ?. ? . ? . ? and the password must be entered again. Repeat step 4.
6. Using Table 6, apply the input value listed for each calibration adjustment step.
For each step, position the rotary switch and apply the input to the terminals as
indicated in the table.
7. After each input value is applied, press G to accept the value and proceed to the
next step (C-02 and so forth).
After pressing G, wait until the step number advances before changing
the calibrator source or turning the rotary switch. If the rotary switch is
not in the correct position, or if the measured value is not within the
anticipated range of the input value, the UUT emits a double beep and
will not continue to the next step. Some adjustment steps take longer to
execute than others (10 to 15 seconds). For these steps, the UUT will
beep when the step is complete. Not all steps have this feature.
8. After the final step, the display shows End to indicate that the calibration
adjustment is complete. Press G to go to meter mode.
Set the calibrator to Standby prior to changing the function switch
position and/or after completing adjustment of each function. If the
calibration adjustment procedure is not completed correctly, the UUT
will not operate correctly.
