6. CALIBRATION
There are 3 types of calibration mode.
6-1 Calibration Mode
6-1-1 Mode
■Digital calibration mode
Calibration shall be conducted not by using the actual load but entering rated output and
rated capacity of sensor with key.
■Actual load calibration mode
It is calibration mode to adjust zero and span with the use of actual load.
■Linearization calibration mode
It is calibration mode to conduct non-linear calibration that reduces the measurement error
through calibration of maximum 4 points excluding zero with the use of actual load
6-1-2 How to select calibration mode
1. It turns into the mode selection status when key is pushed while pushing key is
pushed at measurement status.
2. Mode change and setting value change is available when key or key is pushed at
mode selection status.
3. Push key in order to move onto next stage after saving
the setting value at mode selection status.
3. Push key to cancel the setting and return to measurement mode for mode cancellation.
It is displayed as figure
when pushing no.3 key
while pushing no.2 key.
Change the mode with
No.2 or No.3 key.
(
d-CAL→A-CAL→L-CAL)
Push No.1 key for mode
cancellation.

6-4 Linearization Calibration Mode
6-4-1 Calibration Method
A little measurement error may occur in between the max capacity due to trait of measurement
unit even upon the completion of zero and span calibration. Linearization calibration mode is a
type of calibration mode which conducts non-linear calibration that reduces the measurement
error by conducting calibration with max 4 points excluding the zero with the use of actual load.
