Adjusting Offset and Gain Section 5-7
Offset Adjustment The procedure for adjusting the analog output offset is explained below. As
shown in the following diagram, the set value is adjusted so that the analog
output reaches the standard value (0 V/1 V/4 mA).
The following example uses output number 1 adjustment for illustration. (The
unit number is 0.)
1,2,3... 1. Turn ON bit 00 (the Offset Bit) of CIO word n+1. (Hold the ON status.)
2. Check whether the output devices are connected.
Note The output is current output when using a CJ1W-DA08C.
3. Monitor CIO word n+8 and check the set value while the Offset Bit is ON.
