Make certain that the desired operating mode (isoperibolic, adiabatic, or dynamic) is

set (see Section 8.8 “Configuring the system”). Open the 6DPSOH dialog window to

enter parameters. If a sample rack is active, parameter input is opened automati-

cally by setting or removing a crucible (see also C 5020 Operating Instructions).

Enter the weight of the combustion sample in the :HLJKHG LQ TXDQWLW\ box. If an

electronic scale is connected to the calorimeter system, the weight can be accepted

automatically. Depending on the type of scale, the 6DPSOH dialog window can be

opened either through the sample key of the calorimeter or through the 3ULQWWUDQVIHU

NH\ of the scale. The space bar can be used to accept the scale value again.

You can move the cursor to the following entry boxes with the 7DE key. The mean-

ings of the other entry boxes are as follows:

4([WUDQ Correction for the thermal energy from the cotton thread used as

an ignition aid. A preset value of 50 J/0 J (without/with combustible

crucible) appears here. If you use a different ignition aid instead of

the IKA



cotton thread, change this value as appropriate.

4([WUDQ Correction for the thermal energy from an additional combustion

aid. The preset value is 0.

If the weight of the combustion aid is transferred in :LWKFRPEXV

WLRQDLG mode from electronic scale, the resulting extraneous en-

ergy calculated from the weight appears in the 4([WUDQ box.

Even without a scale, the gross calorific value of the combustion

aid can be taken into consideration automatically. In this case, you

should enter the weighed in quantity of the combustion aid in the

4([WUDQ box and then press the p arrow. 4([WUDQ is calculated

according to the formula

4([WUDQ = Weighed in quantity of combustion aid x

calorific value of combustion aid

and is entered in the 4([WUDQ box. If a value > 10 J is entered, it

is assumed that the value already represents all extraneous en-

ergy4([WUDQ In this case, there is no further conversion based

on the formula given above.
