Adjusting Offset and Gain Section 2-7
Gain Adjustment 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 conversion value is maximized.
The following example uses input number 1 adjustment for illustration. (The
unit number is 0.)
1,2,3... 1. Turn ON bit 01 (the Gain Bit) of CIO word n+1. (Hold the ON status.)
For CS1W-AD041-V1 and CS1W-AD081-V1, the analog input’s digital
conversion values while the Gain Bit is ON will be monitored in CIO word
n+8. For CS1W-AD161, the values will be monitored in CIO word n+17.
2. Check whether the input devices are connected.
