+, 0, and – Keys
The
+
(plus),
0
(zero) and
–
(minus) keys are used to change the currently
displayed position to a different value. The
0
key forces the unit to display 0.
Momentarily depressing the
+
key increments the current position by one unit
of measurement. Momentarily depressing the
–
key decrements the current
position by one unit. Pressing and holding the
+
or
–
keys will cause the
displayed position to change continuously. Holding down the key will cause
the amount of change to speed up. This allows for quick adjustments over a
range of large values. These keys can be “locked out” to prevent accidental
offset or zero entries.

ABS - INC
The Display has two measurement “indexes”. One is referred to as
ABS
and
the other is
INC
. The
ABS
measurement setting is designed to allow the
user to set an “absolute“ zero point on the Display referenced from a fixed or
known position. The
INC
measurement setting is designed to take relative or
“incremental” distance measurements from one arbitrary point to another.
The settings operate independently allowing separate position offsets to be
programmed for ABS and INC. The
ABS
position of the measuring system is
not lost when using the
INC
settings.
ABS
Mode – The Display automatically enters ABS mode when power is first
applied. This is indicated by the ABS symbol in the upper left corner of the
Display. While in the ABS mode, all position measurements are related to
the current system reference point. To enter the INC mode, momentarily
press the
ABS/INC
button.
INC
Mode – While in the INC mode, the INC symbol is shown in the upper
left corner of the Display. When the INC mode is initially entered, the
displayed position will change to reflect a new reference point at the current
