Threshold Setting
Switch to the TEACH mode and set the range in order for the measured value to be
judged as PASS.
Both HIGH and LOW threshold values are set. There are three judgment outputs: HIGH,
PASS and LOW.
There are two ways of setting the threshold value.
• Hysteresis (hysteresis width) can also be set to threshold values. Set hysteresis when judgments are
unstable to prevent chattering.
Setting Judgment Output (HYS) p.6-7
• When setting threshold values while still connected to an external device, set the Sensor Controller’s
LD-OFF input to ON so that the output to the external device remains unchanged. Judgment outputs in
TEACH mode are the same as in RUN mode, i.e., HIGH, PASS, and LOW.
• In Multi-Task mode, you can select the task to be displayed. The function keys correspond to the tasks;
Press the function key for the number of the task to be displayed.
(The currently selected task is displayed as “TKX” on the LCD display.)
Method
Details
TEACHING
(MENU key)
Performs measurement and uses the measurement results to set threshold values.
Position teaching is useful when threshold samples, i.e., with the upper and lower lim-
its, can be obtained beforehand.
DIRECT IN
(L/R/UP/DOWN keys)
The threshold values can be set by directly inputting numerical values. Direct input is
useful when you know the dimensions for an OK judgment or when you want to fine-
tune threshold values after teaching.
