PICCOLO STANDALONE OPERATION
LOCK/UNLOCK BUTTONS
The normal operation of the buttons on the Piccolo unit can be disabled (locked). Then, the user would be
unable to stop or close the unit unless it is unlocked first. This feature allows avoiding accidental actions
during a measurement. The lock/unlock process has no effect on the measurements.
The procedure is the same for locking and unlocking the unit:
1. Press and hold the all three buttons for 3 seconds
2. The meter will display the message “loc” or “unloc” to indicate if the unit has been locked or unlocked.
If the user press one of the buttons once the unit is locked, the “loc” message will be displayed again.
