10. Error Message
10-1. Error message in the Calibration Mode
Err No Origin Solution
Err 20
The resolution is set to be
exceeded the limit 1/10,000
Low the resolution.
The resolution = one division/the allowed maximum weight.
Modify the allowed maximum weight in CAL1 or modify the
division in CAL3 so that the resolution should be below
1/10,000.
Err 21
The resolution is set to be
exceeded the limit 1/10,000
Low the resolution.
The resolution = one division/the allowed maximum weight.
Modify the allowed maximum weight in CAL1 or modify the
division in CAL3 so that the resolution should be below
1/10,000.
Err 22
The weight for the Span
Calibration is set to be less than 10%
of the maximum capacity of the
scale.
Set the weight for the the Span Calibration in CAL4 is set to be
more than 10% of the maximum capacity of the scale(set in
CAL1).
Err 23
The weight for the Span Calibration
is set to be exceeded 100% of the
maximum capacity of the scale.
Set the weight for the Span Calibration in CAL4 to be within the
maximum capacity of the scale(set in CAL1).
Err 24 The Span value is too low.
The setting of current resolution is not possible due to the error in the
load cell or the low output of it.
Proceed the Calibration again with the less resolution.
Err 25 The Span value is too high.
There is a error in the load cell and the output in the load cell is too
high.
Proceed the Calibration in CAL again.
Err 26 The Zero value is too high.
Check whether the platform is empty.
If the SW on the AD PCB is ON, the zero value is decreased.
Proceed the Calibration again after checking in the Test Mode 3.
Err 27 The Zero value is too low.
Check whether the platform is pressed by certain force.
If the SW on the AD PCB is OFF, the zero value is increased.
Proceed the Calibration again after checking in the Test Mode 3.
Err 28 The Weight is unstable.
Check whether the load cell is properly connected.
