Configuration 13
To calibrate the instrument, the Theoretical calibration, Section 2.1.1 on page 13, must be completed first.
After Theoretical calibration is set, the scale can be set with actual weights (see Section 2.1.5 on page 15).
2.1.1 Theoretical Calibration
This function allows load cell rated values to be set.
To perform the theoretical calibration set FS-tEO, SEnS lb and dI UI S (refer to Figure 2-2) in sequence:
1. Press and hold
, then press
to enter set-up menu, CALIb will be displayed.
2. Press ,
FS-tEO is displayed. Press
again.
3. Press
or
until total load cell capacity (system full scale) is displayed, press
.
4. Press
or
until SEnS lb is displayed, press
.
5. Press
or
until desired load cell mV/V is displayed, press
.
6. Press
or
until dI UI S is displayed, press
.
NASS
Enter #
0 *
to
max full scale
Maximum Capacity (Live Load/Product) that can be displayed. When the weight exceeds this
value by 9 divisions, the display will go to dashes, indicating overload.
Setting this value to 0 will disable the over capacity function.
ZErO
0
Used to capture the deadload of the scale system. With the scale empty, the displayed value can
be zeroed off. This menu may also be accessed directly from the weighing mode to compensate for
zero changes or variations.
Press
to display the accumulated deadload weight that has been zeroed off.
I NP 0

0
to
999999
0 *
Estimated dead load value of the scale when a scale contains product that cannot be removed.
The value entered is the dead load. This value will be replaced if the zero function is performed later.
UEIGHt

Weight (Span) Calibration - after the Theoretical Calibration has been completed and zero is set,
the calibration can be adjusted with actual test weights by changing the displayed value in this
parameter.
If changes are made to the theoretical Full Scale (FS-tEO ), the Sensitivity (SEnSIb )
or Divisions (dI UI S ) parameters, the Weight (Span) Calibration is cancelled and
the Theoretical Calibration is initiated and applied.
If the theoretical full scale (FS-tEO ) and the capacity full scale (NASS ) are equal in Weight
(Span) Calibration (WEIGHt ), then the calibration currently in use is theoretical; if they are
different, the calibration in use is the Weight (Span) Calibration based on calibration weights.
If changes are made to the theoretical full scale (FS-tEO ), the capacity full scale (NASS ) or
divisions (dI UI S ) parameters, all the system’s parameters containing a weight value will be
set to default values (setpoints, hysteresis, etc.).
