Triplett 1101a - Manual (Page 19)

8:
BACKLIGHT AND HOLD
8.1 Backlight:
The 1101-A incorporates a light green LED backlight into the LCD
assembly. Since the backlight uses more power than anything else in
the meter, an anti-tease function on the button prevents accidental
turn-on, and a 20 second time-out prevents extended battery drain.
To turn on backlight, press and hold the Backlight / Hold button for
about 3 seconds, until the backlight comes on. Release the button. The
backlight will stay on for about 20 seconds and then turn itself off.
8.2 Hold:
A Hold feature is incorporated into the 1101-A. It is a momentary
Hold feature that only holds a reading as long as the associated button
is kept depressed. Since the button that performs Hold is also the
Backlight button, if the Hold feature is engaged for longer than 3
seconds, the Backlight will turn on.
To activate the Hold feature, press and hold the Backlight / Hold
button. The Hold annunciator will appear in the LCD display for as
long as the button is held depressed.
