Intelligent Auto Power Off (APO)
The Intelligent Auto Power Off (APO) mode turns the meter off automatically to extend
battery life after approximately 17 minutes of no activities. Activities are specified as: 1)
Rotary switch or push button operations, and 2) Significant measuring readings of
above 10% of range or non-OL Ω readings. In other words, the meter will intelligently
avoid entering the APO mode when it is under normal measurements. To wake up the
meter from APO, press the RECORD button momentarily or turn the rotary switch to
the OFF position and then turn back on again. Always turn the rotary switch to the OFF
position when the meter is not in use.
Disabling Auto Power Off
Press the RANGE button while turning the meter on to disable the Auto Power Off
(APO) feature.
