4 SETUP AND PROCEDURES BEFORE OPERATION
POINT
(1) If the offset/gain setting mode is set using intelligent function module switch 4,
other settings by switch 4 (settings for resolution mode and temperature drift
compensation) will be ignored.
(2) Setting of the offset/gain setting mode differs from function version A to
function version B. (Refer to Appendix 1.3)
Perform the offset/gain settings after checking the RUN LED flashes in
offset/gain setting mode. If the RUN LED does not flash, check to see if the
switch 4 setting is correct.
(3) Since the digital output value will differ considerably, depending on the
resolution mode setting, thoroughly check the settings for the intelligent
function module switches before performing the digital output processing.
Example) Digital output value when the setting range is -10 to 10 V and a 10 V
analog value is added.
