11. Error Message
11-1 Errors that can occur in weight calibration mode
Error Cause Solution
Err 20
The set resolution has exceeded the
allowance limit of 1/30,000.
Lower resolution.
Resolution = maximum allowed weight/value of 1 increment.
Adjust maximum allowed weight in CAL 1 of weight calibration
mode or adjust the value of 1 increment in CAL 3 of weight
calibration mode to adjust to below 1/30,000.
Err 22
The counterweight for span
adjustment has been set to less than
10% of maximum weighing scale
capacity.
Set the counterweight weight as greater than 10% of the maximum
scale capacity (set in CAL 1) in CAL 4 of weight calibration mode.
Err 23
The counterweight for span
adjustment has been set to exceed
100% of the weighing scale
capacity.
Set the counterweight weight to within the maximum weighing
scale capacity (set in CAL 1) in CAL 4 of weight calibration mode.
Err 24
Span is too low.
Setting the present resolution is not possible as there is an issue with
the load cell or the load cell output is too small. Reset the weight
calibration by reducing the resolution.
PCS, PERCENT Sample weight is too small
Err 25 Span is too high.
There is an issue with the load cell or the load cell output is too high.
Redo steps from weight setting CAL 4 zero-set adjustment.
PCS, PERCENT Sample weight is too great.
Err 26 Zero-set is too high.
Check if the load plate of the weighing scale is clear.
After verifying in Test Mode 3, redo the weight calibration.
Err 27
Zero-set is too low.
After checking the force applied to the weighing scale load plate in
Test Mode 3, redo the weight calibration.
Err 28 Weight is unstable.
Check if the load cell connector is properly connected.
