The settings for Analog Input modules are as follows:

An arbitrary input value can be treated as the Zero Scale (i.e. a 4-20mA input is capable of generating
a 0 to X output).
a 0 to X output).
Using the Optional Analog Outputs
The four optional Analog Output ports can output energy pulses to an RTU or
perform equipment control operations. Both types of Analog Output (either 0-
20mA or 0-1mA) can deliver a continuous DC signal. Analog Output modules
control these hardware ports.

You use ION Designer to create and configure these ION modules. Create an
Analog Output module for each output port you are going to use, and link their
Source input to a value you want to reflect through the analog outputs. Alter the
setup registers as required:

Setting Zero Scale for 4 to 20mA Outputs
If you want your 9300 meter’s 0 to 20 mA analog output ports to operate as 4 to 20
mA outputs (i.e. delivers a 4 mA current with a zero Source input value to the
Analog Output module), use the following formula:
mA outputs (i.e. delivers a 4 mA current with a zero Source input value to the
Analog Output module), use the following formula:
Zero Scale = - 0.25 * Full Scale
For example, with a Full Scale value of 100, your Zero Scale setting would be -25.
