CLEARING THE DISPLAY/CANCELLING
AN ACTION
When pressed briefly, the triple-function button:
1. Works like the “Clear Entry” button on a calculator to
clear the last value entered in a calculation sequence
2. Works like the “Undo” command on a computer menu
to cancel the last action selected
3. Works like a “Reset” button to “zero-out” individual
measurement/calculation values stored in memory
(see pp. 24 and 25) in chronological order, oldest first
CHANGING THE MEASUREMENT UNIT
The LDM60’s default distance measurement unit is feet +
fractional inches, expressed as X’Y’’. The default area
measurement unit is square feet, expressed as ft
2 . The default
volume measurement unit is cubic feet, expressed as ft 3 .
To temporarily change the distance measurement unit,
press and hold the
button as many times as necessary until
the desired unit appears at lower right. The options, in order, are:
meters (m), feet (ft, expressed as a whole number plus a decimal
fraction), inches (in) and ft + in (expressed as X'Y", where X is a
whole number and Y is a whole number plus a common fraction).
When the meter is powered off and on again, the distance
measurement unit automatically resets to the default: feet +
fractional inches.
TURNING THE BACKLIGHT ON AND OFF
To turn the display backlight on, press the
button briefly.
The backlight will remain on for 1 minute and then automatically
turn off (without sounding a beep) to conserve battery charge.
To turn the backlight off, press the
button briefly again. The
default state is backlight off.
