4-3-2-5. LINEARIZE CALIB.
The linearity of load measurements is improved by increasing
the calibration points.
Do this after actual load calibration.
1
Touch the ON button to enable linearization
calibration.
2
Touch the number of linearization point (calibra-
tion point) to input on the right side of the screen.
3
After inputting the load applied to the sensor in the
"OUTPUT VAL." field, apply the load, and touch the
enter button.
The "OUTPUT VAL. " cannot be set to a value that would
be 5% or more relative to the straight-line (reference
line) that connects the no load and rated load outputs.
ATTENTION
The following conditions must always be met.
o 0 < output value < rated capacity
o Output value of lower-numbered calibration point
< output value of higher-numbered calibration point

4
Confirm the input value. Then, touch ESC to return
to the previous screen.
5
Repeat steps 2–4 to input necessary calibration
values, and touch the OK button.
NOTE
o The calibration waveform shown on the LINEARIZE (ACTUAL
LOAD CALIB.) screen is an illustration, not the actual calibration
curve.
o After linearization calibration value input, touch the OFF
button to disable linearization calibration. Since input cal-
ibration values are saved, touching the ON button will
enable linearization calibration.
o To disable a specific calibration point, touch its number so
that its background color disappears
In the illustration below, calibration point 2 is disabled.
o The possible range of linearization is shown by the dashed
lines in the illustration below.
