Totalization with the keys
F Ï ∏
If the GM303 Control Unit is attached or the
LabPac-M is used with SM scales or high-
capacity PM scales, the totalization of
individual weights can be performed without
the LabPac-M terminal.
Preparation
• Attach LabPac-M terminal
• Activate net total application
• Store application with
• Remove LabPac-M terminal
The scale can now be used for totalization.
Note
Clear the stored application with
switches between current component
weight and last net total
adds the actual component weight to the
net total, sets the display to zero
resets all entries except date, time and
stored values
