– Turning the display backlight OFF conserves battery power (if the instrument
has the Battery option).
– If the instrument is operating from battery power (Battery option required), the
display backlight is automatically turned off after a period of inactivity. When
activity is subsequently detected (a measurable signal is applied, a front-panel
key is pressed, or a setting is changed by a command sent over the GPIB or the
RS-232 interface), the display backlight is restored to its previous state (i.e., if
the backlight was set to
OFF
, it remains off; if the backlight was set to
ON
, it is
turned on).
