Potentiometer
A potentiometer to readjust (fine-adjust) ZERO (4mA) and
GAIN (20mA) is placed on the rear panel.
(The adjustable range is a few percentage.)
(4mA and 20mA are factory-adjusted.)
10-4-3. Method of Adjusting the D/A Zero and Gain
The D/A converter of the F701-C obtains analog output by setting the weight value to output 4mA
of current and the weight value to output 20mA of current, respectively. Input each setting value
and select D/A Output Mode in setting mode 4.
