5-8. Digital Zero (DZ)
The Gross weight is forcibly zeroed by this function. The Net weight changes according to the
following expression: (Net weight) = (Gross weight) - (Tare weight).
If the digital zero operation is performed where Gross weight exceeds the DZ Regulation Value
(Please refer to "5-10.Zero Regulation Value" on P.62.), “ ” flashes to give a warning of the
problem.
In this case DZ Regulation Value is subtracted from Gross weight.
Operation
1) Press → .
2) Gross is zeroed.
- Digital zero by external signal
By short-circuiting A3pin (D/Z ON) and COM on the control connector, Gross weight is
immediately zeroed.
Net weight changes according to the following expression:
(Net weight) = (Gross weight) - (Tare weight).
* In a case where 0 is not indicated when performing digital zero operation or when “ ”
flashes, the following causes are considered.

Cause Measure
Digital zero operation was performed
when the DZ Regulation Value
(default value 200) was exceeded.
- Change the set value of the DZ Regulation
Value and perform digital zero operation
again. (However, since this is a temporary
measure, perform Zero Calibration at an
early time.)
- Remove lightweight residue adhered to the
tank.
- Check that there is no mechanical contact.
