Backlit Display Time (bLIt)
Back light of the meters can be turned off
automatically with a timer. Once set, back light will
remain on for the period of the timer setting upon
enabling the back light by pressing and holding
for two seconds. If it is set to “OFF”, the
back light will remain ON indefinitely.
Selectable parameters:
OFF, 1 – 99 seconds
Note: To conserve and extend battery life, select a
shorter timer setting.
Bright Level Off State (bOFF)
This option allows users to set the brightness level for
the “off state” of the back light. The “off state” refers
to the state after backlight is enabled and backlight
timer (bLit) ends. For example, this option is used
when users want backlight to be enabled for a period
of time (set by bLit) and then dim the brightness
indefinitely afterwards. When set to “OFF”, back light
will be off in the off state. If a level is set, the backlight
will be on with the selected brightness level after
backlight is enabled and backlight timer ends.
