4-1. Calibration Procedures
Follow the steps below to perform equivalent input calibration and actual load calibration.
Release the calibration protection.
Set the calibration value No.
(Set "0" for use with only one selection.)(This step
may be omitted if there is no change.)
Set the excitation voltage according to the sensor
used.
Set the unit of the values displayed.
Set the zero point of the strain-gage sensor in no-
load condition (with the sensor unloaded).
Equivalent Input Calibration
Enter the rated output value and reading of the
strain-gage sensor.
At this time, also input the decimal point.
Actual Load Calibration
Enter the span (gain) point of the strain-gage
sensor with a load applied to the sensor.
At this time, also input the decimal point.
Enter the minimum value of digital increments.
(This step may be omitted if there is no change.)
The calibrated value can be offset in advance.
(When not using, set "0".)
(This step may be omitted if there is no change.)
Set the load limit to allow digital zero.(This step
may be omitted if there is no change.)
Turn on the calibration protection for preventing
misoperation.
