Linear Output

■
The default linear output settings are listed in the following table. These settings are set at the factory and also after initializing
the settings.
Default linear output setting
Voltage output ±4 VDC
(See Note)
Current output 4 to 20 mA
(See Note)
Note: Use the monitor focus function when setting the output voltage to

Discrimination Outputs
There are three discrimination outputs: HIGH, PASS, and LOW.
The following table and illustration show the timing of each output.
Threshold Values
The threshold values form the boundaries between the HIGH,
PASS, and LOW outputs for the measured value.
There are two threshold values: The HIGH threshold and the
LOW threshold. The threshold values contain hysteresis.
Measured value
Larger than or equal to HIGH threshold
Smaller than or equal to HIGH threshold − Hysteresis
Smaller than or equal to LOW threshold
Larger than or equal to LOW threshold − Hysteresis

Hysteresis
The hysteresis (hysteresis width) is the difference between the
operating and releasing values. If the hysteresis is too small, chat-
tering may occur. If it is too large, releasing may be difficult.
