9.4.3 Using Analog Power-Save Mode
On your 831C, go to
Tools
System Properties
, then press the top-right
softkey (
//*
) until the
Power
tab displays.
Power-Save mode is indicated by the sleep icon
. When the meter is not
running, this mode can significantly conserve battery power, since it shuts
down the meter’s analog circuitry and signal processing activities.
From the
Power-Save
drop-down menu, select the period the instrument
should stay powered after a measurement has stopped.
The analog circuitry, including power to the preamplifier, shuts down when
the instrument is stopped for the period you chose. Performing a calibration,
a reset, or starting a measurement restores power. The meter can run the
measurement after a short 10 second power-up.

Tools
System Properties
, then press the top-right
softkey (

Backlights On
is the duration the 831C display is back lit after the last key
press. Selecting

slightly increases power consumption.
9.4.5 Enabling or Disabling the Keypad Backlight

Tools
System Properties
, then press the top-right
softkey (

The blue LEDs under the keypad can be enabled or disabled according to your
preference. The Red LED behind the STOP/STORE button, and the green LEDs
under the RUN/PAUSE and ON/OFF buttons are always enabled.
TAKE NOTE
Increasing the back light brightness significantly increases the meter’s power
consumption, which decreases battery life.
Additionally, you can select the LCD screen back light intensity as a
percentage.
When battery life is below 10%, the 831C overrides this setting and
downgrades the LCD Brightness to 50%. If the user-defined setting is below
50% brightness, it remains the same.
