Analog Output Units
Section 5-2
The possible range of offset adjustments depends on the output range. Refer
to the following table.
Note An output range of 4 to 20 mA is possible only with the GT1-DA04.
If the output corresponding to 0% is outside the range of possible adjustments
shown in the above table, check the connection to the output device.
Gain Adjustment
Gain adjustment is used to adjust the rate of fluctuation of output conversion
values so that when the value corresponding to 100% in the output range is
written, it is converted accurately to output 100%. Gain adjustment is used
when the greater the output voltage and output current, the greater the differ-
ence from the actual value due to the features of the Unit or the method of
connection being used.
The possible range of gain adjustments depends on the output range. Refer to
the following table.
Note An output range of 4 to 20 mA is possible with only the GT1-DA04.
