Setting Thresholds
3-2-3 Forced-zero Setting
To set the thresholds, a measured value based on a reference
workpiece is first set as zero. A tolerance is then added to and
subtracted from the reference value (zero) to set the results as
HIGH and LOW thresholds. Forced-zero settings are possible
only if the unit is set to mm.
The HIGH and LOW thresholds are kept on hold when the refer-
ence workpiece is changed, which enables easy changeovers.
Thresholds are displayed between –9.999 and F.S. (see note),
but the linear output voltage will not change.

1 "F.S." stands for full scale. In the case of the Z4LB-S10V2,
for example, the F.S. value is 10 mm.
