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

–10 to 10 V
1 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 IR word n+1 ON and then OFF again.

While the Gain Bit is ON, the gain value will be saved to the Unit's EEPROM
when the Set Bit turns ON.
5. To finish the gain adjustment, turn OFF bit 01 (the Gain Bit) of IR word n+1.
