Auto Power Off (APO) Feature Disable
The meter automatically powers itself down after about 30 minutes of no use. Press
any button, and the meter will wake up and enter the default function of that setting.
To Disable APO, press and hold the SEL button while turning the dial to any desired
function. When APO is defeated, the “APO” will be removed from the display.
Turning the meter off and back on will restore the APO default.
LoZ (61-757 Only)
Low impedance measurements defeat the influence of ghost or stray voltages on
the displayed value which are often caused by induced voltages coupling from one
parallel conductor to the next as found when measuring one conductor in multiple
conductor circuits.

backlight/flashlight on and off. The white backlight and flashlight will remain lit for

the lights off by pressing and holding the button more than 2 seconds again.
