INCREMENTAL MEASUREMENTS
The readout has two measurement modes, or indexes. One is referred to as
ABS or Absolute, and the other as INC, or Incremental. The absolute
measurement mode allows the operator to read the current position of the
encoder referenced from a fixed or known position-usually zero.
The incremental mode allows the operator to make relative distance
measurements from one arbitrary point to another. The absolute position of
the DigiScale is not lost when using the incremental mode.
Absolute: The readout automatically enters ABS mode when power is first
applied. This is indicated by the ABS
ABSABS
ABS symbol in the upper left corner of the
display. While in the ABS mode, all encoder positions are related to the
current ABS, or absolute system reference point.
Incremental: To enter the INC mode, press and hold the UNITS key for
approximately 3 seconds. The INC
INCINC
INC symbol will appear in the upper left corner
of the display. When the INC mode is entered the readout will display zero
(0) or the last offset if one was entered, and may be changed by using the +
or - keys to provide a different offset. Moving the encoder 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 UNITS key. The readout will again change to
0 (or the previously programmed offset). To return to the ABS mode, press
and hold the UNITS key for approximately 3 seconds.
NOTES: when the readout is in incremental measuring mode the UNITS key
no longer functions to change the measurement units displayed.
The absolute position of the DigiScale is not lost when using the incremental
mode. When the readout is switched back to the absolute mode the readout
reflects the current encoder position relative to your original calibrated
absolute setting.
