6 Calibration
The calibration is an operation that matches the load of the load cell to the display of this
unit to display the electrical signal from the weighing section (load cell) as accurate load.
If the calibration is not processed, the correct display and the output cannot be taken.
For instance, this is the calibration that the display of this unit is to become a display of
100.00 kg accurately when the weight of 100 kg is applied on the weighing section.
6.1 Set items required in weighing calibration
-
Load cell excitation (BRIDGE POWER SUPPLY)
This is the voltage (DC) supplying for load cell. The setting value is selectable from
[12V], [6V] or [3V]. [12V] is set as default.
-
Scale interval (DIVISION)
This is the minimum unit of weighing value. The setting value is selectable from [1],
[2], [5], [10], [20] or [50]. The value of "Weighing capacity / Scale interval (Min. scale
division)" is the display resolution.
-
Maximum load (Max) (WEIGHING CAPACITY)
This is the maximum load that can be measured in the weighing section (load cell).
-
Zero calibration (ZERO ADJUSTMENT)
This is the calibration that the weighing value becomes zero point of the scale when
no load is applied (Initial load condition) on the weighing section. There are two
calibration methods of "Weighing value (Initial load condition)" and "Numeric input of
load cell output voltage".
-
SPAN calibration (SPAN ADJUSTMENT)
This is the calibration that the changes of the electrical signal from load cell become
the display of right weighing value when the weight is put on the measuring section.
There are two calibration methods for calibration of "weight" and "numeric input of
output voltage of a load cell".
6.2 Set items if necessary after the calibration
-
Fine calibration at ZERO and SPAN (FINE ADJUSTMENT)
-
Pitch conirmation registration (PITCH COMFIRMATION)
-
Digital linearise (DIGITAL LINEARISE)
-
Position of decimal point (DECIMAL POINT)
-
Display condition of OL (OL DISPLAY CONDITION)
-
Unit (UNIT)
-
Compensation of gravitational acceleration (ADJ. GRAV. ACCELERATION)
