General Functions
5.1.1.
Zero Adjustment
Zero adjustment is a function to set the gross weight to zero.
It is performed by pressing the
(ZERO)
key.
The zero adjustment range is set in
( Zero range ) and is expressed in percent of the
weighing capacity with the calibration zero point as the center.
Zero adjustment is disabled, even within the zero adjustment range, when the A/D converter
overflow occurs.
A ZERO error is output if zero adjustment is not performed.
The zero value is stored in the non-volatile memory and is maintained, even if the power is
disconnected.
Clearing the zero value is performed using the
key assigned to clear the zero value.
Functions Related To Zero Adjustment
( Zero range ) : A value between 0% and 100% can be specified.
( Tare and zero adjustment when unstable )
:
The selection to enable or disable
tare and zero adjustment when unstable.
( Zero setting when power is turned on )
:
The selection whether or not to perform
zero setting when power is turned on.
5.1.2.
Zero Tracking
The zero tracking is a function to track the gross weight drift around the zero point to maintain zero.
The zero tracking time is set in
( Zero tracking time ) and the zero tracking width is
set in
( Zero tracking width ). When the gross weight drift is within the specified
ranges, zero tracking is performed automatically.
A ZERO error is not output even if zero tracking is not performed.
Functions Related To Zero Tracking
( Zero tracking time )
:
The value between 0.0 and 5.0 seconds can be specified.
( Zero tracking width )
:
The value between 0.0 and 9.9 d can be specified.
(d = minimum division)
5.1.3.
The Tare Function
Tare is a function to store the gross weight as the tare value and set the net weight to zero.
It is performed by pressing the
(TARE)
key.
The tare weight is stored in the non-volatile memory and is maintained, even if the power is
disconnected.
Clearing the tare weight is performed using the
key assigned to clear the tare weight.
Functions Related To The Tare Function
( Tare and zero adjustment when unstable )
:
The selection to enable or disable
tare and zero adjustment when unstable.
( Tare when the gross weight is negative )
:
The selection to enable or disable
tare when the gross weight is negative.
