better resolution, switch to 1/32 or 1/64 mode. For the best resolution and
accuracy switch to a decimal mode – inches or millimeters.
When the measurement is greater than 99 63/64 inches, a +100
+100+100
+100 and/or
+200
+200+200
+200 will illuminate in the upper right portion of the display to indicate this
amount must be added to the displayed reading. ie: If the measurement is
154 5/8 inches, 54 5/8 and +100
+100+100
+100 will be illuminated on the display. If the
measurement is -307 23/64 inches, - 7 23/64, +100
+100+100
+100 and +200
+200+200
+200 will be
illuminated on the display.
+ AND - KEYS
The + (plus) and – (minus) keys are used to change the currently displayed
position to a different value.
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.
DATUM KEY
The DATUM key forces the readout to display a user programmed value.
See Section 3: Programming, Programming Parameter Pr1.
NOTE: While the DATUM key can be used to simply “zero” the currently
displayed value, it can also be programmed to force the readout to a preset
value. This can be zero, or any other displayable value.
Readout Functions
REVERSE READINGS
Reverse readings means changing the direction of readings produced by
moving the encoder. If the readout decrements (reduces or goes negative)
when it should be incrementing (increasing or going positive), the readout will
need to be re-programmed for your application.
See Section 3: Programming, Programming Parameter Pr2.
