The Display at a Glance
To view the full display (with all segments illuminated),
press and hold button while turning the rotary
switch from OFF to any non- OFF position. After you are
done viewing the full display, press any button to resume
normal functionality based on the rotary switch position.
This is followed by a wake- up feature.
The meter will then enter power save mode once auto power
off (APF) is enabled. To wake the meter up:
1 Turn the rotary switch (knob) to OFF position, and then
turn it back on again.
2 Press any button for rotary switch position that is not at
square wave output position. This is only available for the
U1252B.
3 For the U1252B only, to set the rotary switch at square
wave out position, press only the Dual, Range and Hold
buttons or turn the rotary switch to another position.
The LCD signs are described on pages 10, 11 and 12.
