Calibration Adjustment Procedure

Downloaded from Elcodis.com electronic components distributor
The Meter keys behave as follows when performing the calibration adjustment procedure.
T stores the calibration value and advance to the next step.
H ignores the calibration value and advance to the next step. This key is also used to exit
calibration function after the calibration adjustment sequence is complete.
Use the following steps to make calibration adjustments to the Meter. If the Meter is
turned off before completion of the adjustment procedure, the calibration constants are
not changed.
1. Remove batteries from UUT battery compartment. Connect a + 5.0 V lab supply
to the + and - battery terminals.
2. While holding down L, turn the rotary function switch from OFF to VAC.
The Meter displays CAL.
3. Press the blue button once to see the calibration counter.
4. Press blue button again to start the password entry. ---- appears on the display.
5. Press four keys to enter the password.
6. Press the blue button to go to the first calibration step. The Meter displays C-01 if
the password is correct. If the password is not correct, the Meter emits a double
beep, displays ---- and the password must be entered again. Repeat step 4.
7. Using Table 9, apply the input value listed for each calibration adjustment step.
For each step, position the rotary function switch and apply the input to the
terminals as indicated in Table 9.
8. After each input value is applied, press T to accept the value and proceed
to the next step (C-02and so forth).
After pressing T, wait until the step number advances before
changing the calibrator source or turning the Meter rotary function switch.
If the Meter rotary function switch is not in the correct position, or if the
measured value is not within the anticipated range of the input value, the
Meter 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 Meter will beep when the step is complete. Not all steps
have this feature.
9. After the final step, the display shows End to indicate that the calibration
adjustment is complete. Press H 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 Meter will not operate
correctly.
