Setting Thresholds
- T Mode
In this mode, set the measured values for a PASS (OK) judgment. Both HIGH and LOW
threshold values are set. Three judgment results are output; "HIGH", "PASS" and "LOW".
The following describes, as an example, the operation procedure for setting a HIGH threshold.

Set the value.
In the special mode (IC lead pitch or IC lead width judgment mode), the following values are
output:
HIGH:Standard value setting
LOW: Tolerance setting
Measurement Cycle p.61
Move from one digit to another.
Change the current value.
Confirm the selection.
Hysteresis can also be set for threshold values. Set hysteresis when judgments are unstable.
