+, 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” using the LOCK MODE to prevent accidental offset or zero entries.
Changing Resolution
The Readout can be configured to read .001in / .01mm (high resolution) or .01in /
.1mm. (normal resolution), fractions remain the same in both settings.
To change resolution you will need to remove the Readout cover. Inside, on the circuit
board, you will see a series of jumpers. To display high resolution place JP2 in the A
position. To display normal resolution place JP2 in the B position.
Incremental Measurements
To make Incremental measurements, press and hold MODE key for approximately 3
seconds. This switches the Readout to INCremental mode (as shown on the LCD).
You can now press the ZERO, + or – keys if desired. Any measurement taken will be
an incremental measurement and you will not lose your original ABSolute position. The
Readout can be repeatedly re-zeroed (for repeated incremental measurements) by
pressing the ZERO key. To recall + and -offsets entered while in INC mode, simply
press the MODE key. (Measurement Mode changes are not allowed while in INC
mode). To return to the ABS measuring mode, press the MODE key for 3 seconds.
Lock Mode
The user can “lock-out” the position offset adjustment functions
(+, -, 0
keys) to prevent
accidental changes of the current displayed position. To activate the lock mode, press
and hold the
ON/OFF
key and then momentarily press the
MODE
key. The
measurement units (
in
or
mm
) on the LCD display will blink when the Readout is in lock
mode, and the
+, -
and
0
keys will not change the displayed position.
