11-2. Current Output (DAI Option)

This converter is used to obtain an analog output which is linked with the
indicated value of the F320.
The range of the analog output is from 4 to 20mA.
An analog output from 4mA to 20mA can be obtained with respect to any digital
values set by the D/A zero setting and the D/A full scale setting functions.
The output circuit and the main circuit are isolated.

Zero adjustment trimmer
Trimmer to adjust so that the current output becomes
zero when the indication is as registered by the D/A
zero setting function.
The zero adjustment range is approx. 3.6 to 4.4mA
(at the time of zero output).
