Calibration Information

Meter Buttons Used in the Calibration Steps

For the Calibration Adjustment Procedure, the Meter buttons behave as follows:
• 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.
• Press and hold M to display the required input value.
• 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.
• Press Q to toggle the backlight on and off.
This can be useful to determine why a calibration step is not accepted and to determine the input value without
referring to Table 5.

Calibration Adjustment Procedure

If you turn off the Meter before completion of the adjustment procedure, the
calibration constants do not change.
To adjust the Meter calibration:
1. 110/114/115/116/117:
While pressing K, turn the rotary switch from OFF to Ω function.
113:
While pressing q, turn the rotary switch from OFF to Ω function.
The Meter should display ZCAL.
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 Table 5 and Table 6.
Some adjustment steps require additional wait time after the calibrator settles,
as noted in Table 5 and Table 6.
7. After each input value is applied, press g to accept the value and proceed to the next step (C002).
After you press g, wait until the step number advances before you change
the calibrator source or turn the rotary switch. Some adjustment steps can
take up to several seconds to execute before the next step.
If the rotary switch is not in the correct position for a given step, the meter will
flash the unit annunciators until the rotary switch is put in a valid position. The
keys that show the reading and required input values are not allowed until the
rotary switch is correct.
If the rotary switch is not in the correct position or the measured value is not
within the anticipated range of the input value, the Meter will emit a double
beep and will not continue to the next step when you press g.
After the final step, the display shows End to indicate that the calibration adjustment is complete.
8. Press g to return to meter mode.
