The following apply to evaluating successful calibrations:
05)> @
The average relative error < 0.2 % (according to ISO 1928)
'LII
The deviation range as a percentage < 0.4 % (according to
DIN 51900)
Other criteria may also apply depending on the standard you are using. The values
given above, however, will be sufficient to fulfill customary requirements of accuracy
for a calorimeter.
k
Use
7DE
to place the cursor on the
>±!@
button and confirm with
2.
or press
. The
average value of the selected calibration experiments will thus be assigned to the
calorimeter system as the system heat capacity or C value. If you place the cursor
on
> ±@
press
2.
, you can enter the system heat capacity manually in the
& YDOXH
field.
l
Place the cursor on the experiments that were not used to calculate the average
value and delete them with
'HO
cc
Exit the dialog box with
2.
The system calibration is thus complete and you can
now continue with the determination of gross calorific values.
