printed.
- With the multitasking mode, the weighing&control process will
not be interrupted by parameter setting and the other operations.
Keypad Operation
If there is not any keypad operation in one minute and it’s not in
the processes of ‘F2 Calibration’ & ‘F6 Factory Adj.’, the
controller will return to ‘Main Display Interface’ automatically.
