11-2-1. Obtaining Current Output Signal
Use the + and - terminals of the F320 for connection with an external device
(350
Ω
or less load resistance).
11-2-2. Setting of D/A Zero and Gain
With the D/A converter of the F320, an analog output is obtained by setting the
indicated value to output 4mA (D/A zero set value) and the indicated value to
output 20mA (D/A full scale set value). Respective set values are inputted by the
D/A zero and full scale setting functions.
