9 Setting Test Parameters
9.1 Select
Mode
To simplify the test parameters modification procedure, test parameters can be preset. The user
can select a set of base settings by selecting a single mode number. The tester provides modes
1 to 13 on STANDBY 1 screen and 14 to 26 on STANDBY 2 screen (refer to Section 9.2: How to
Set Test Parameters on Page 29). Each mode allows the following parameters to be set:
(1) Initial Heating 1 : Initial heating temperature setting 1 (0 to 999.9
°
C)
(2) Initial Heating 2 : Initial heating temperature setting 2 (0 to 999.9
°
C)
(3) Final Heating Starting Point : Percentage of distillate for final heating (80 to 95%)
Set to 91.5% for group 1 and 2 samples and 93.5% for group 3
and 4 samples.
(4) Final Heating : Final heating voltage [(AUTO)
±
98% or (MANU) 0 to 98 V] Usually set to
(AUTO)+00%.
(5) Temperature Range : 300 (0 to 300
°
C to cover ASTM 7C thermometer)
400 (0 to 400
°
C to cover ASTM 8C thermometer)
P200 (0 to 200
°
C for BTX and solvents)
P400 (0 to 400
°
C for solvents)
(6) Residue : Expected residue (0 to 9.9%)
(7) Distillation Rate Setting: Control distillation rate (2.0 to 9.0 ml/min)
Usually set 4.5 ml/min.
(8) Condenser Bath Setting : Condenser bath control temperature (0 to 69.9
°
C)
(9) Receiver Compartment Temperature : Receiver compartment control temperature (0 to
69.9
°
C)
The above test parameters are displayed on the STANDBY screen.
In addition, the following test parameters are provided as options (refer to Section 9.2: How to
Set Test Parameters on Page 29):
(10)
Loss Calculation Method :
Choice of a method for calculating a loss
(graphical [GRAPH] or arithmetical [ARITH])
(11)
Distillation Temperature Accuracy :
Distillation temperature rounding (0.1 or 0.5
°
C)
(12)
Distillation Volume Accuracy :
Distillation volume rounding (0.1% or 0.5%)
(13)
Manual Heater Control :
Manual heater control (ON or OFF)
(14)
Both EP and DP Measurement :
Measurement of end point and dry point (ON or OFF)
(15)
Hesitation Point Correction :
Linear correction of hesitation points (ON or OFF)
(16)
Data Printout :
Test result printing (ON or OFF)
Set OFF not to print test results by the printer of this device.
(17)
Distillation Temperature Cutoff :
Test end at a set distillation temperature (0.1 to 399.9
°
C)
(18)
Distillation Volume Cutoff :
Test end at a set distillation volume (0.1 to 99.9%)
(19)
IT&Rate Auto Setting :
Automatic setting of the initial temperature for a sample of
unknown boiling point and distillation rate at 5% to 10% (OFF, INIT or RATE). When
testing a sample of an unknown boiling point, select “INIT”. After the first running, AD-6
calculates appropriate IT1 and IT2 temperature, and then records them to the mode.
This tester sets the initial temperature and enters the temperature automatically into IT1
and IT2 after the test. After the test, return the setting to OFF automatically.
After settlement of IT1 and IT2, change this setting to “RATE” and then run the same
sample again. After the running, AD-6 calculates appropriate heater output so that
distillation rate around 5 to 10% will be fit for the test condition. The distillation rate around
