Zero Operation
In GROSS mode, remove all weight from the scale and wait until the scale has settled.
A scale in motion will show the symbol “
~
“ in the lower right hand corner of the screen
to indicate the scale has not settled. A scale that will not settle may have the Motion
Tolerance parameter established during SETUP adjusted too small for the environment.
Press the ZERO button, a message “ZERO OK” will briefly be displayed and the scale will
show
000.00
, indicating the ZERO command was successful.
If “ZERO FAILED” is displayed, the Zero command was unsuccessful. Check the
Zero Tolerance parameter established in Set Up to determine if the zero amount has
exceeded the maximum cumulative value that can be zero’d off the scale.
NOTE The amount of weight zeroed off each time is cumulative. The zero command will fail
if the current gross weight plus any previously zeroed amount exceeds the zero
tolerance established in the SET UP parameters.
