Set the backlight timer


To conserve battery pack power, set the timer to automatically turn off the backlight after a specified period of inactivity, such as no data collection or key presses. After the timer expires and the backlight is turned off, press a key or the screen to turn on the LCD backlight and reset the timer. The timer is disabled when the power supply is connected to and powers the analyzer.

Unlike standby mode, the blue LED on the front of the analyzer does not display when the backlight is off.
