Here you can specify whether you will enter the 6DPSOH name yourself in the
6DPSOH QDPH configuration box and in the 6DPSOH dialog box, or whether
the system will automatically assign the 6DPSOH QDPH . If you do not select
this option, the system assigns experiment numbers in the 6DPSOH QDPH
box.
> @ 2 ULQVLQJ
With this option, the decomposition vessel is briefly filled with oxygen, after
which the oxygen is released each time, before the actual filling with oxygen.
The purpose of this is to remove atmospheric nitrogen.
> @ FRPEXVWLEOH FUXFLEOH
This option reduces the value for extraneous energy by 50 Joules since no
cotton thread is used.
> @ 'HFRPSRVLWLRQ
If the sample is to be subjected to a subsequent decomposition after it has
undergone combustion, the decomposition vessel must be depressurized
outside of the calorimeter. To do this, a special depressurization station
C 5030 is connected (there is no automatic depressurization of the decom-
position vessel).
0RGH configuration box
In this box, you can select an option for the temperature control of the water
jacket in the outer vessel. The following options are available:
,VRSHULEROLF The temperature of the water jacket is regulated to a
constant temperature.
$GLDEDWLF The temperature of the water jacket is regulated ad-
justed to match the temperature of the inner vessel.
'\QDPLF The combustion experiments are performed according
to a quick procedure.
$GMXVWPHQW Internal parameters of temperature control are deter-
mined for this option. The device has been adjusted
during the functional test in the factory. It possesses a
temperature compensation so that under normal labo-
ratory circumstances no adjustment is required when it
is first placed in service. For more detailed information,
see Section 14.3 “Adjustment”.
5HIHUHQFH JURVV FDORULILF YDOXH >-J@ configuration box
In most cases, certified benzoic acid is used. The indicated gross calorific
value should be entered. If you are working with another reference combus-
tion substance, you must enter the gross calorific value of this combustion
substance here yourself.
([SHULPHQW LQLW configuration box
You can use the experiment initialization to specify how the SDUDPHWHUV 8VHU
DQG 6DPSOH SURSHUWLHV should be set in the 6DPSOH dialog box, as well as all
parameters in the ([SHULPHQWV dialog box. These setting options are dis-
cussed again in Section 11, “Determining gross calorific values”. The follow-
ing options are available:
