Back Light and Battery Status

Application for Back Light

The liquid crystal display (LCD) on the Model 8718B Meter

provides high contrast in bright outdoor lite. However, LCD’s do

not generate any light and can be difficult to read in low light

conditions. The LCD on the 8718B contains a high brightness

back light that can be turned on whenever it is needed.
The only disadvantage to using the back light is that it consumes

much more energy than the meter circuits and significantly

reduces operating time between battery charges.

Controlling the Back Light

To turn the back light on or off...

1. Access the menu system by pressing the function key

that corresponds to the legend below MENU on the

bottom line of the display.

2. Press 4 to select BAT/LITE from the First Menu Screen.

A new screen will appear that indicates both battery

status and back light status.

3. Press F3 (ON) or F4 (OFF) to turn the back light on or

off as required.

4. Press the ESC key to return to the First Menu Screen.

Press it again to return to the measurements screen.
