Offset/Gain Setting
If the user range is necessary, set up the offset/gain setting by following the instructions as illustrated below.
Note that using the factory default range does not require the offset/gain setting.
1.
Turn off the module power supply.
2.
Set x10 of the station number setting switch to O/G.
3.
Turn on the module power supply and check that
the LEDs are in the following state:
RUN LED: Off
O/G LED: On
4.
Select the setting target using SET/SEL button.
5.
For the selected channel, adjust the analog output
value by using the "+" and "-" switches.
Pressing the "+" switch increases the analog output
value. Pressing the "-" switch decreases the analog
output value.
6.
Keep pressing
button until the RUN LED lights
up.
Once the RUN LED lights up, release
button.
While the RUN LED lights up, the offset value or gain
value is being written to the non-volatile memory.
Upon completion of the write, the RUN LED goes out.
Check that the RUN LED goes out, and go to the next
step.
