Turning On/Off the Backlight
The LCD can be back-lit. Pressing the
key turns on the backlight,
while pressing the key once again turns it off. This feature makes it
easier for you to view the LCD when operating the calibrator in dark
places or when carrying out source or measurement. Note that battery
life shortens when the calibrator is operated on batteries.
NOTE
The backlight automatically turns off approximately one minute later. To turn
on the backlight again, press the
key once again.
