4.1
mA input setting (Ad)
First set the application of mA input to “Current”, “Temperature” and “Pressure”, then 0% value,
100% value of each, according to the application.
This function is available when mA input/output is “-A4” in the suffix code. When mA input/output
is “-A2”, mA input is not settable.
If you do not set mA input (Ad), set the application to “None”.

4.1.1
Application
Select mA input application out of “None”, “Current”, “Temperature” “Pressure”.
4.1.2
Damping time
This is the time taken for a response to a step input change to reach 90% of the final value
(attenuation time).
4.1.3
AI Upper Limit/AI Lower Limit
Set AI upper/lower limit for error detection of upper/lower limit. The lower limit must be lower than
the upper one.
4.1.4
Temperature (4 mA/20 mA)
Set each value for 0% (4 mA) and 100% (20 mA) to use mA input as temperature parameter. The
value has to be different from each other.
4.1.5
Pressure (4 mA/20 mA)
Set each value for 0% (4 mA) and 100% (20 mA) to use mA input as pressure parameter. The
value has to be different from each other.
4.1.6
Pressure Comp. (*)
Exclusively for Optical DO Sensor.
Pressure Comp. has to be set to “Enable” so that you can conduct pressure compensation with
the pressure value by mA input.
Once you change the setting, the pressure value input starts compensating the pressure
and keeps it updated every 2 hours. When you are on “Enable” and turn the power on, the
compensation starts 2 minutes after the power on.
