Display Features - Satec Expertmeter EM720 Operation Manual

Chapter 3 Using Front Display Display Operations
If the phase voltage is either missing or below the voltage
interruption threshold, the phase indicator is replaced with
a dash.

Display Features

The EM720 display has a number of programmable
features that can be disabled, enabled and adjusted via
the meter Display Setup (see Display Setup in Chapter 5).
Backlight
A short press on any button while the display backlight is
off switches the backlight on.
The backlight stays on as long as you selected in the
display setup and then dims to conserve power. The
backlight time is factory set to 1 minute and can be
programmed from 1 to 10 minutes. You can temporarily
set the backlight to continuous operation if you need to
work in dark for more time.
The backlight is not operational if voltages are missing on
meter terminals while the meter is powered from the
battery.
Auto-Return
If the Auto-Return feature is enabled and no button is
pressed for the defined Auto-Return interval
(programmable from 1 to 30 minutes for data displays;
fixed at 5 minutes for setup menus), the display
automatically returns to the start page of the present
billing period's display from any other data display or a
setup menu.
If the Auto-Scroll feature is also enabled, the display
immediately enters the auto scroll sequence.
Auto-Scroll
If the Auto-Scroll feature is enabled, the data display
automatically scrolls through all pages of all data displays
that are included into the programmable auto-scroll
sequence. The scroll interval is adjustable in the range of
2 to 30 seconds. The scroll sequence may include all or
only selected displays.
The display automatically enters auto scrolling if no button
is pressed for the Auto-Return interval if the Auto-Return
feature is enabled in your meter, or in 1 minute if this
feature is disabled. In the latter event, the scroll sequence
is restored from the point where it was interrupted.
To stop auto scrolling, press briefly any button if the
backlight is on; else press briefly any button twice since
the first press only sets the backlight on and does not
affect auto scrolling.
Auto-Scroll is not operational in TEST mode.
