G4 Multi Channel Weighing Instrument
Operation
Zero indication and zero adjustment
A basic zero setting of the gross weight for unloaded scale is performed at installation
as a part of the calibration. When a ‘good zero’ is displayed, the letter ‘Z’ is shown
under the measurement value.
Minor correction of the zero value may be needed and can rapidly be performed.
Zero adjustment
If, for unloaded scale, the letter ‘Z’ is not shown, but the gross weight is close to zero, a
rapid zero adjustment can be performed.
The gross weight must be stable (letter ‘M’ not shown)
and the zeroing function must be enabled.
Press key ↑ .
Additional functions for the scale will appear
to the right on the bottom line.
Use key + or – to scroll to the Additional function
'Zero'.
Press key ↵ to perform zero adjustment.
Gross weight, adjusted to zero, is displayed.

Zero adjustment can only be performed if the accumulated deviation from the basic
zero setting in the last calibration is within -1 % to +3 % of the ‘Capacity’.
In other cases a new basic zero setting must be executed.
Gross weight and net weight
The gross weight is the total weight loaded on the scale after zero setting.
When gross weight is displayed the letter 'G' is shown under the measurement value.
The net weight is the difference between the gross weight and a tare value.
When net weight is displayed the letter 'N' is shown under the measurement value.
Net weight can not be displayed if the tare value is zero.
Switch-over between display of gross weight and net weight can be performed if
parameter 'Gross/Net key' is set to 'On'. This makes the additional function 'B/N'
available for the scale.
