7.4. Calibration Errors
When an error occurs during calibration, the error number is displayed.
If calibration is finished without releasing the error, the setting values will be restored to
the state before calibration.
Calibration errors and remedies
Error No.
Description
Remedy
C err1
The display resolution (weighing
capacity / minimum division) exceeds
the specified value.
Make the minimum division
greater or make the
weighing capacity smaller.
The specified value
depends on the instrument
or specifications.
C err2
Voltage at zero calibration exceeds in
the positive direction.
C err3
Voltage at zero calibration exceeds in
the negative direction.
Check the load cell rating
and connection.
When nothing is wrong with
the rating and connection,
adjust the load cell output
as described in the next
section.
When the load cell or A/D
converter may be the cause
of error, confirm it by using
the check mode.
C err4
The value of the calibration weight
exceeds the weighing capacity.
C err5
The value of the calibration weight is
less than the minimum division.
Use an appropriate
calibration weight and
calibrate again.
C err6
The load cell sensitivity is not sufficient.
Use a load cell with higher
sensitivity or make the
minimum division greater.
C err8
The load cell output voltage is too high
when the load of the weighing capacity
is placed.
Use a load cell with a
greater rating or make the
weighing capacity smaller.
C err7
Voltage at span calibration is less than
voltage at the zero point.
Check the load cell
connection.
