selected, and parameters for load value and transducer signal will be displayed only
for the selected number of points.
It is possible to change the number of points during the calibration.
Value Cal. P1,
This parameter defines the load for the lowest calibration point. Normally the scale
should be unloaded and the parameter value set to 0 (zero). This weight value and
the corresponding transducer signal value are automatically stored in the instrument.
The instrument will display actual gross weight when the user attempts to store the
value (pressing enter button when ‘Value Cal. Px’ is selected). Pressing enter button a
second time stops the weight display and the ‘Value Cal. Px’ can be entered.
Value Cal. P2, Value Cal. P3 etc.
The scale should be loaded with known weights. These parameters show the load
according to the previous calibration and the parameter values should be changed to
the value of the known weights. As a parameter value is stored, the instrument will also
store the corresponding transducer signal value for that calibration point.
T. Signal P1, T. Signal P2 etc.
These parameters contain the automatically stored transducer signal values for
the calibration points. The values cannot be edited.
Set Zero
Set zero is useful only when the scale installation is finished. By the digit keys this
value can be set to zero, for unloaded scale, or to the weight of the known load, for a
scale that is loaded.
The instrument will display actual gross weight when the user attempts to set zero
(pressing enter button when ‘Set Zero’ is selected). Pressing enter button a second
time stops the weight display and the ‘Set Zero’ value can be entered.
Zero Offset
For an installed scale this parameter shows the zero offset after zeroing, a value that
should not be edited, but recorded in the Set-up list.
Calibration indication
When a new deadweight calibration is started an asterisk character will be shown at the
end of ‘Value Cal. P1’, ‘Value Cal. P2’ etc. This indicates that this value is not entered.
The asterisk will disappear when the user has entered a value. If the user leaves the
calibration menu, i.e. calibration is interrupted, the remaining asterisks will be removed. It
will still be possible to continue the calibration later on but without any calibration
indications (asterisks).
Note that as long as there are asterisks visible it will not be possible to edit the ‘Set Zero’
or ‘Zero Offset’ parameters. First must the deadweight calibration be finished (no asterisks
visible) then should the zero be set.
