8.5 Setting sample temperature
The following key operation is common to this detector unit or the operator interface/display unit.
(1) Press SEL key for 2 seconds to enter into the calibration curve
setting mode.
(2) Press SEL key several times to enter into the sample
temperature setting mode (tS).
(3) Set the sample temperature.
(
Setting range: -999.9 to 999.9
)
8.6 Setting 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: Assuming that the group 1 has been selected,
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.
Further, set the sample temperature T1. For its setting, refer to [8.5 Setting 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 into the Ti 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), the values for the first calibration
curve number in a group are used.
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
