Display Error description
This indicates a state in which Zero calibration cannot be performed
because an electric signal exceeding the input voltage range is input
on the positive side. Check the cable for breaks or wrong wiring.
This indicates a state in which Zero calibration cannot be performed
because an electric signal exceeding the input voltage range is input

Sensor rated capacity value is preset to “0”.
Select a proper non-zero value.
The output of the strain gauge type sensor is too small to perform
calibration. Check to see if load is applied properly, or the strain
gauge type sensor has such a capability that can make appropriate
output, and then perform Span calibration again.
Strain gauge type sensor output is outside the F331’s allowable
sensor input range. Check if the sensor is properly loaded, and the
its rated output falls within the F331’s sensor input range. Perform
Span calibration again. Then, perform Span calibration again.
Display Message description
Invalid ZERO key operations.
Zero calibration in progress.
Actual load calibration in progress.
