4-3-1-6. LINEARIZE CALIB.
The linearity of load measurements is improved by increasing
the calibration points.
After equivalent input calibration, input the linearization
calibration.
1
Touch the ON button to enable linearization
calibration.
2
Touch the number of the linearization point (calibra-
tion point) to input on the right side of the screen.
3
Input the calibration values (output and load val-
ues) and touch the OK button.
The "LOAD 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 output
o Output value of lower-numbered calibration point
< output value of higher-numbered calibration point

4
Confirm the input values. 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
(EQUIVALENT 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.
