8.8 Setting of calibration curve data
(1) Specify a group for calibration curve number to be used.
The groups are from 1 to 10 and each one corresponds to the following calibration curve
numbers respectively.
Group 1: Calibration curve number 1 to 10 Group 6: Calibration curve number 51 to 60
Group 2: Calibration curve number 11 to 20 Group 7: Calibration curve number 61 to 70
Group 3: Calibration curve number 21 to 30 Group 8: Calibration curve number 71 to 80
Group 4: Calibration curve number 31 to 40 Group 9: Calibration curve number 81 to 90
Group 5: Calibration curve number 41 to 50 Group 10: Calibration curve number 91 to 99
(2) Example: Select the group 1.
Set the following calibration curve at the sample low limit temperature T1 to the
calibration curve No. 1.
Y = a3X
3
+ a2X
2
+ a1x + a0
Only the calibration curve by polynomial expression can be used. (The calibration curve
by broken line approximation cannot be used.)
Further, set the sample temperature T1. For its setting, refer to [8.7 Setting of sample
temperature].
(3) Set the calibration curves at the sample temperature Ti ( i= 2 to 10) to the calibration
curve numbers 2 to 10.
However, Ti should fulfill the following expression.
T1 (Sample low limit temperature)
T2
……….
T9
T10 (Sample high limit
temperature)
(4) Enter 999.9 at the Ti, which is not used. Be careful that, if this value is not entered, a
calibration curve not used is computed as a data.
* The default of the sample temperature Ti is 999.9.
(5) For the correction expression coefficients b1 and b0 and the constants (low limit range,
high limit range, low limit alarm, high limit alarm and preset value), use the values for
the first calibration curve number in a group.
Group 1: Calibration curve number 1 Group 6: Calibration curve number 51
Group 2: Calibration curve number 11 Group 7: Calibration curve number 61
Group 3: Calibration curve number 21 Group 8: Calibration curve number 71
Group 4: Calibration curve number 31 Group 9: Calibration curve number 81
Group 5: Calibration curve number 41 Group 10: Calibration curve number 91
