Starting from
PHQX
, for a calibration, press the
button once to go to
PHQX
.
Then press function key
I
, to enter the sub-menu
FDOLE
. For a calorific value deter-
mination, press function key
I
in
PHQX
to go to sub-menu
SUHSDU
. In both sub-
menus, the enquiry
VDPSOH FRGH
appears.
d
The
VDPSOH FRGH
identifies a test. Use of this code word will later provide access to
the test data. A specified sample code will appear in the upper left zone of the LCD-
display for all further entries. The calorimeter generates a sample code automati-
cally when it is switched on, which consists of the date and the number of the cur-
rent test (00 to 99). The number increases by 1 for every new test. If you do not wish
to use these automatic sample codes, use the alpha-numeric keys to enter your own
code word for the test. Up to 9 consecutive alpha-numeric characters can be en-
tered. Confirm by pressing the
↵
button. The enquiry
XVHU
appears in the LCD-
display.
e
Use the alpha-numeric keys to enter the name or initials of the operator. Here too,
up to 9 consecutive alpha-numeric characters can be entered. Confirm by pressing
the
↵
button. The enquiry
TH[WU
appears in the LCD-display.
f
TH[WU
is the sum of
DOO
sources of external energy. The preset entry here is
50 Joule. This is the calorific value of the cotton thread C 710.4, which you can pur-
chase from IKA
. Use the key panel to set this value correctly for the current test.
When using combustible crucibles or other combustion aids, their weight in grams
can be entered manually using the key panel, or read automatically from a con-
nected balance. Manual entry is made using the alpha-numeric keys after selecting
the menu level
PDQXDO
with function key
I
. The calorimeter accepts only values
greater than zero. For automatic input from the balance, use function key
I
to call
up the menu level
EDODQFH
. The mass of the sample as determined by the balance
will be read in automatically.
It is now necessary to enter the calorific value of the combustion aid. The last value
entered always appears here as a default value. If necessary, erase this value by
pressing the
GHO
button repeatedly. Once these two entries are completed, the calo-
rimeter automatically calculates the external energy supplied by the combustion aid.
