• Evaluation procedure ASTM D1989, D240, D5865, D4809, D5468, E711

For calibration, a dialog reduced to the acid-correction fields and a shortened

results form are displayed. The comments in Section 9.2 under Point } apply

here too.

• Evaluation procedure DIN/IKA

In the DIN/IKA evaluation procedure, the acid correction to ASTM D240 or

ASTM D1989 can also be used for calibration. The results form is shortened ac-

cordingly. The other calculation modes are not available for calibrations.

The calibration experiments are listed in the dialog box. The meaning of the col-

umns in the list of experiments is as follows:

1R The running number of calibration experiments

&YDOXH The heat capacity of the calorimeter system determined with the

experiment in question

([SHULPHQW The 6DPSOHQDPH of the relevant experiment

Use 7DE to place the cursor on 6HO and confirm with 2. or press the  key. You

have thus selected the experiment for calibration. The experiment is marked on the

display with “

√

”.

Use 7DE and 8SDUURZ to place the cursor on the next experiment and press 6HO.

This will select the next experiment for calibration. The average value of the se-

lected experiments, the average relative error by percent, and the deviation range

(max/min) absolutely and by percentage are displayed in the corresponding fields.

$YHUDJH Calculated mean value

05)>@ Average relative error (German abbreviation)

0D[0LQ Deviation range

'LII The range of deviation as a percentage in reference to the average

value

Repeat Step 6 for all values that are to be selected. $YHUDJH will then display the

average C value of these experiments.
