Calibration Information
2. With a small probe, break the Calibration Seal and press the Calibration Button for 1 second. The
Meter will beep and change to the calibration mode. The display reads C-01, designating the first
calibration step. The Meter remains in calibration mode until the Rotary Function Switch is turned off.
3. Proceed through the calibration steps by entering the input value listed in the table for each step.
When calibrating or measuring AC current, avoid the potential for errors from coupled noise, by either:
1. Shorting the VeG to the COM input
or
2. Having NO connection to the VeG input.
After pressing the YELLOW button, wait until the step number advances before changing the calibrator
source or turning the Rotary Function Knob.
4. After each input value is applied, press the YELLOW button to accept the value and proceed to the
next step (C-02 and so forth).
5. When the last step in a function is reached, turn the Rotary Function Knob to the next required
function. The Meter will not allow a step to be completed if the Rotary Function Knob is turned to the
wrong function.
If the calibration adjustment procedure is not completed correctly, the Meter will not operate
correctly. When calibration adjustment is not performed correctly, the Meter displays the messages
"CAL" and "Err"and the Meter must be recalibrated.
The Meter is damaged and requires service if:
"CAL" and "Err" messages continue to appear after a proper recalibration.
"EEPr" and "Err"messages are alternating on the display.
"EEPr" message appears on the display.
