Meter Buttons Used in the Calibration Steps
When performing the Calibration Adjustment Procedure, the Meter buttons behave as follows. This may be of help
in determining why a calibration step is not accepted and for determining the input value without referring to
Table 4.
1. Press and hold K to show the measured value. The measured value is not calibrated so it may not
match the input value. This is normal.
2. Press and hold M to display the required input value.
3. Press g to store the calibration value and advance to the next step. This button is also used to exit
calibration mode after the calibration adjustment sequence is complete.
4. Press Q to toggle the backlight on and off.
Calibration Adjustment Procedure
To adjust the Meter’s calibration, use the following steps:
Note
If the Meter is turned off before completion of the adjustment procedure, the calibration
constants are not changed.
1. While holding down K, turn the rotary switch from OFF to Ω function. The Meter should display
“CAL”.
2. Press g once to see the calibration counter.
3. Press g again to start the password entry. The Meter displays “????”.
4. Press the 4 button password.
5. Press g 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.
6. Apply the input value listed for each calibration adjustment step. For each step, select the rotary switch
position and apply the input to the terminals as indicated in the Table 4.
