Qualifier Meter
1-11
Backlight
As a standard feature, the LCD is provided with a backlight to enable the instrument’s use in
low lighting conditions. Backlights require extra power and will significantly reduce
available battery life.
The Qualifier meter features automatic backlight deactivation and reactivation at strategic
points during normal use. Pressing the
LIGHT key illuminates the backlight. After 10
seconds, the backlight automatically deactivates. After deactivation and prior to power-
down, the backlight will reactivate with each function keypress as well as with the
LIGHT
key, automatically deactivating 10 seconds after each keypress. When the backlight is on,
pressing the
LIGHT key turns the backlight off.
