3. Input the voltage or current so that the conversion value is maximized
(0FA0 or 07D0 at a resolution of 4,000). The following table shows the gain
adjustment voltages and currents to be input according to the input signal
range.

0 to 5 V
4 to 20 mA
4. With the voltage or current having been input so that the conversion value
for the Analog Input Unit is maximized (0FA0 or 07D0), turn bit 04 (the Set
Bit) of CIO word n+1 ON and then OFF again.
