Restoring The Default Password - Fluke 110 Calibration Information Manual

Restoring the Default Password

If the calibration password is forgotten, the default password (1234) can be manually restored:
To prevent electric shock or personal injury, remove the test leads and any input signal before
removing the Meter's back case.
1. Remove the Meter back case. Leave the PCA in the top case.
2. Apply 9.0 V across the battery contacts (XBT1) + and (XBT2) – on the back of the PCA. See Figure 6.
3. Turn the rotary switch from OFF to any ON position.
4. Short across the S7 CAL keypad on the back of the PCA. See Figure 6. The Meter should beep. The default
password is now restored.
5. Remove the 9.0 V supply and replace the Meter back case.
