Name
Description
Analog voltage output
This outputs the measured value from -10 V to +10 V as the voltage value.
When measurement not possible: Approx. 10.8V (default value, can be selected by user)
At alarm: Approx. 10.8V
Analog current output
This outputs the measured value, from 4 mA to 20 mA as the current value.
When measurement not possible: Approx. 21 mA (default value, can be selected by user)
At alarm: Approx. 21 mA
Name
Description
HIGH output
Judgment result HIGH (HIGH threshold value < measured value) is output.
PASS Output
Judgment result PASS (LOW threshold value
measured value
HIGH threshold value) is
output.
LOW output
Judgment result LOW (LOW threshold value > measured value) is output.
Name
Description
ALARM output
This turns ON when there is a system error.
Name
Description
BUSY output
This turns ON during sampling with the hold function enabled.
It allows you to check whether or not the self-trigger is functioning correctly.
It also turns ON during bank switching.
Name
Description

This turns ON when the sensor is ready for measurement.
This output is interlocked with the ENABLE indicator.
Name
Description
ZERO input
This is used to execute and clear a zero reset.
