When a calibration error is displayed, take measures according to the error message, and do zero
calibration again.

* Each CC-Link error code consists of:
Error code
...The initial tare is above the Zero adjustment range.
Remove any excess load from load cell or scale. If cErr2 is still
displayed, connect a resistor between +EX and -SIG load cell
connections. This should shift the Zero point. Do Zero Calibra-
tion again.
For the relationship between the resistance connected and input
signals, see the next page.
...The initial tare is minus.
Check that load cell is mounted in the correct direction; check
that load is being applied to the load cell in the correct direction;
check that the +SIG and -SIG lines are properly connected.
If cErr3 is still displayed, connect a resistor between -EX and -
SIG load cell connections. This should shift the Zero point. Do
Zero Calibration again.
For the relationship between the resistance connected and input
signals, see the next page.
...The weight value is not stable.
Adjust the parameters for motion detection, check that the
STAB status is "ON", and then do zero calibration again.
