Calibration with calibration weights (zero and end value / partial load):
The procedure with and without partial load calibration does not differ. Partial load calibration
means that the calibration weight deviates from the scale nominal load.
NOTE
The commands LDW and LWT are performed only at standstill. Otherwise the answer
?CRLF is output and the value is not stored. If no standstill is reached, a very sensi-
tive characteristic has been set possibly by an earlier calibration. The WE2108 should
then be set to a standard characteristic with the following commands:
