6 Calibration
The operation of matching the device display with the weight on the load cell is called
calibration.
It facilitates accurate display of the electrical signal from the load cell as a weight.
For example, calibration adjusts the display of the instrument to 100.00 precisely when a
weight of 100 kg is placed on the load cell.
6.1 Calibration setting items
- Scale interval ([D-01], [02], [05], [10], [20], [50])
The minimum unit of the weight value to be set is [1], [2], [5], [10], [20] or [50].
Maximum load/Scale interval (Minimum scale division) is the display resolution.
- Maximum load ([DISP])
This is the maximum weight to be able that can be weighed by the load cell.
- Calibration weight used in SPAN calibration ([LOAD])
SPAN calibration can be executed with an arbitrary weight. The same setting as the
maximum load is used if there is a maximum load value.
Use a calibration weight that has mass of at least 2/3 of the maximum load in order to
minimize calibration error.
- Zero point calibration ([ZERO])
This procedure calibrates the zero point for weight with nothing on the load cell
(status of initial load). Calibration methods comprise "Method by weighing operation
(status of initial load)" and "Method by numeric input of load cell output voltage.”
- SPAN calibration ([SPAN])
This procedure calibrates the change in the electric signal from the load cell when a
weight is placed on the load cell to the correct weighing value. Calibration methods
comprise "Method by weighing operation (status of initial load)" and "Method by
numeric input of load cell output voltage.”
6.2 Parameters to be set where necessary after calibration
- Decimal point display position (C function: [CF-01])
A decimal point is included on the weight display of this unit.
- Unit (C function: [CF-05])
The unit is included on the weight display of this unit.
- Digital linearization ([LNR])
This function compensates up to three points, excluding the zero and SPAN points, to
reduce the weighing error (refer to Chapter 6.5 ).
- Automatic range switch (C function: [CF-40] to [CF-44])
This is the setting for the second range or the third range [Multi scale interval scale].
The limit value and the scale interval within the each range are set (refer to
Chapter 8.14 ).
- Gravity acceleration compensation (C function: [CF-25], [CF-25])
