6.3.2 Procedure for setting
1) Press SEL key for 2 seconds to enter into the calibration
curve setting mode “CH”.
2) Press key. A numeric blinks for entering a calibration
curve number.
3) Change the numeric by key, key or key.
Press key to increase the numeric.
Press key to decrease the numeric.
Press key to shift the blinking digit.
4) Press ENT key. The numeric stops blinking and the
calibration curve number is stored.
5) Press SEL key to enter into the setting mode “A0” for
polynomial coefficient
a
0
.
6) Enter into a numeric setting mode by pressing key.
Change the numeric by key or key and store it by
pressing ENT key. For entering a decimal point, press
CH/
・
key at the blinking digit.
7) Press SEL key to enter into the next data setting mode.
8) Repeat the above procedure from 2) to 7) to set all data.
9) After the above setting procedure is completed, return to the measurement mode by pressing
SEL key for two seconds. The automatic return is made if no key is pressed for one minute.
6.3.3
Correcting calibration curves
If the actual constituents does not correspond with the constituents on the calibration curve being
preset due to the difference of one-line and off-line measurements, or other causes, correct it with
the correction coefficients b
0
, b
1
and b
2
in [6.3 Setting calibration curve data]. These coefficients
are provided for the quadratic expression correction against the measured value “y”. Assuming that
the measured value after correction be “Y”, we obtain,
Y = b
2
y
2
+ b
1
y + b
o
Usually, the shift correction is done with b
0
only. (b
1
= 1, b
2
= 0)

Calibration curve number setting
The settings shown in the next paragraph can also be executed via the operator
interface/display unit (sold separately).
[Example 1: Moisture measuring]
When the measured moisture content before correction is 15 (%H
2
O) and the
actual moisture content is 13 (%H
2
O), “-2%H
2
O should be set.
