10-2-1. Obtaining Current Output Signal
Use + and - terminals of F340A connecting to them an external equipment (with load
resistance of 350
Ω
or less).
10-2-2. Setting of D/A Zero and Gain
With the D/A converter of the F340A, 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.
