4.1 mA input settings (Ad)
First select the application of mA input from “Current”, “Temperature”, “pH” or “Conductivity””,
then set 0% value, 100% value of each, according to the application.
This function is available when mA input/output is “-N4” in the suffix code. When mA input/output
is “-N2”, mA input is not settable.
If you do not set mA input (Ad), set the application to “None”.

4.1.1 Type
Select mA input application out of “None”, “Current”, “Temperature”, “pH”, “Conductivity”.
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). The unit is second.
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 pH (4 mA/20 mA)
Set each value for 0% (4 mA) and 100% (20 mA) to use mA input as pH parameter. The value
has to be different from each other.
4.1.6 Conductivity (4 mA/20 mA)
Set each value for 0% (4 mA) and 100% (20 mA) to use mA input as conductivity parameter. The
value has to be different from each other.
