The Auxiliary Keypad is found only on Digital Displays that are Fully Programmable
(See Programming Parameter 9. Factory default is all keys enabled.)
ABS - INC
The Digital 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 a
current position on the display referenced from a fixed or known position such as a saw
blade, or stop. The INC measurement setting is designed to take relative distance
measurements from one arbitrary point to another. The systems operate independently
allowing separate position offsets to be programmed. The ABS position of the measuring
system is not lost when using the INC settings.
ABS Mode – The ProScale 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
(i.e. sawblade, stop, origin etc.) 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 position of the readhead. This is typically a
position of zero (0) but may be changed by using the + or - keys to provide an offset.
Moving the readhead in either direction will display the distance moved from the initial
INC starting point (plus any offset). To complete another incremental measurement from
the new position, momentarily press the ABS/INC key. The display will again change to
0 (or the previously programmed offset). To return to the ABS mode, press and hold the
ABS/INC key for approximately 3-4 seconds.
HOLD
The Digital Display provides a feature that allows the displayed position to be “frozen” in
time while the readhead is moved from its measuring position. This allows
measurements to be captured on the display and held for later viewing regardless of the
current readhead position. To activate the HOLD mode, momentarily press the HOLD
key. The HOLD symbol will be shown in the upper left corner of the display. The
currently displayed position and selected key presses will be frozen at this point. To
release the HOLD feature, momentarily press the HOLD key again.
