Offset and Gain Adjustment
Gain Adjustment
1, 2, 3...
The procedure for adjusting the analog input gain is explained below. As shown
in the following diagram, the gain is adjusted by sampling inputs so that the con-
version value is maximized.
0FA0
Input signal range:
0 to 10 V
The following example uses input number 1 adjustment for illustration. (The unit
number is 0.)
1. Turn ON bit 01 (the Gain Bit) of IR word n+1. (Hold the ON status.)

The analog input's digital conversion values while the Gain Bit is ON will be
monitored in IR word n+8.
2. Check whether the input devices are connected.

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.
