Err 01
▣ Reason
The weight is too unstable to initialize the scale
☞ Trouble shooting
Lay the scale on a plat place and turn on the power.
Err 02
▣ Reason
Load cell connection failure or error in A/D conversion part.
☞ Trouble shooting
Check the load cell connector to see if the polarity of signal is reversed.
Err 06
▣ Reason
Error in printer connection
☞ Trouble shooting
Check with printer connector
If there is no problem with printer connector, please request
A/S to head office.
Err 08
▣ Reason
The ZERO key or TARE key is adjusted not to be operated under the unstable
condition.
☞ Trouble shooting
Press ZERO or Tare key in stable condition
Err 09
▣ Reason
Current weight deviates from zero range.
☞ Trouble shooting
Press zero key within 10% of the maximum capacity.
Err 13
▣ Reason
Tare weight exceeds the maximum capacity of the scale.
☞ Trouble shooting
Set the tare to be smaller than maximum capacity.
Otherwise the maximum capacity is reset to be larger than the tare to be
set in the calibration menu, and reset the calibration using weight.
