(9) Auto Power Off (APO)
If the meter idles for more than 10 minutes, the meter automatically turns the power off. When this
happens, the state (non-logic measurement) of the meter is saved, the meter can be turned back on by
pressing any switch or changing the rotary switch. If the meter is Re-Powered by pressing a switch, the
LCD display the saved state, press the Hold switch to disable the hold state. The meter will alarm 15
seconds before automatically turning power off, any key press or rotary change will reset Auto-Power-Off.
(10) Disable Auto Power Off
In order to disable auto power off function, power up the meter while pressing down any switch other than
the “Hold” and “NCV” switch.
