DETAILED SETTINGS
Entering Threshold Values
Threshold values are set to determine the range for PASS judgements. Both HIGH and LOW
threshold values are set. There are three judgement outputs: HIGH, PASS, and LOW.
The following table outlines the two methods for setting the threshold values.
Hysteresis (hysteresis width) can also be set for threshold values. Set hysteresis when judgements are
unstable to prevent chattering.
p. 80
When making settings while still connected to an external device, set the Amplifier Unit judgement’s output
hold input to ON so that the output to the external device remains unchanged. The judgement outputs in T
mode will be the same as in RUN mode, i.e., HIGH, PASS, and LOW.
Method
Details
Direct input
Sets threshold values by direct numerical value input.
Direct input is useful when you know the dimensions for an OK judgement or when
you want to fine-tune threshold values after teaching.
Position teaching
Performs actual measurements and uses the measurement results to set threshold
values.
Position teaching is useful when threshold samples, i.e., with the upper and lower
limits, can be obtained beforehand.
