The thermoreactor CR 3200 is a dry temperature control device for
laboratory use. It facilitates and secures the digestion using reaction
cells.
The thermoreactor has 8 fixed temperature programs.
1: 148 °C for 120 minutes
2: 120 °C for 30 minutes
3: 120 °C for 60 minutes
4: 120 °C for 120 minutes
5: 100 °C for 60 minutes
6: 148 °C for 20 minutes
7: 150 °C for 120 minutes
8: 100 °C for 30 minutes
8 more temperature programs can be set up freely. The reaction
temperature can be adjusted from room temperature to 170 °C, the
heating time from 0 to 180 min.
The thermoreactor takes 24 reaction cells with an outer diameter of
16 mm.

4.2Operating modes
The thermoreactor has three operating modes:
Standby
The display shows the model and version number of the
thermoreactor.
Using the g and e keys simultaneously takes you to the SETUP
menu. There you can:
– Edit the 8 temperature programs and the temperature test
program (setting the temperature and reaction time for the
programs 9 to 16 and T, see section 5.5.1)

time is started (START TIMER:MAN. or AUTO, see section
5.5.3)
Program selection
After switching on with e the display shows the current
temperature value for the thermoblock. The second display line
shows the temperature programs and the temperature test program
to be selected if a reaction time of at least one minute has been set
(see section 5.5.1). The control lamps above he display light up
green.

5.1Inserting the reaction cells
The reaction cells can either be inserted at room temperature or when
the thermoreactor has been preheated.
Caution
When dealing with chemicals always follow the safety data sheets
and the regulations for prevention of accidents.
Caution
Observe the analysis specifications of the test sets used.
Warning
The thermoblock can become very hot (170 °C).
There is danger of burning when the thermoblock is heated up.
Note
When cold reaction cells are inserted in the preheated thermoblock it
can cool down by approx. 3 °C.
1Insert the filled reaction cells in the cell shafts.
2Close the protection cover.
5.2Starting a temperature program

3Start the displayed temperature program with g.
The control lamps for the thermoblock flash red.
The nominal reaction time (in hours and minutes) appears on
the display.
Note
The reaction temperature is reached when the temperature in the
thermoblock is in a range of ± 1 °C around the adjusted temperature
for two minutes constantly. The control lamps of the thermoblock will
then light up red.
Sequence with
automatic timer
Sequence with manual
timer
If the start of the timer for the reaction time has been set to automatic
in the SETUP menu (START TIMER:AUTO see section 5.5.3), the
reaction time automatically starts after the reaction temperature has
been achieved. The reaction temperature is kept constant during the
reaction time.
After the reaction time has expired the control lamps flash red.
The temperature program is finished.
The thermoreactor is in the program selection mode.
As soon as the thermoblock has cooled down to under 50°C, the
control lamps switch themselves off.
If the start of the timer for the reaction time has been set to manual in
the SETUP menu (START TIMER:MAN. see section 5.5.3), an S is
displayed in front of the nominal reaction time. With this setting the
thermoreactor controls the temperature until the timer for the reaction
time is started by pressing g.
4Start the timer for the reaction time with g. The S in front of
the reaction time disappears.
20
The reaction temperature is kept constant during the reaction time.
The control lamps of the thermoblock will then light up red.
After the reaction time has expired the control lamps flash red.
Additionally, an acoustic signal sounds.
5Using g confirm the end of the reaction time for each
thermoblock.

CR 3200Operation
The thermoreactor is in the program selection mode.
As soon as the thermoblock has cooled down to under 50°C, the
control lamps switch themselves off.
5.3Stopping a temperature program
You can terminate a running program at any time.
1Using 46, terminate the running temperature program.
The control lamp for the thermoblock flashes red/green.
The safety query STOP? is displayed.
2Using g confirm the safety query STOP?.
The temperature program is finished.
The control lamps of the thermoblock will then light up green.
or:
Using 4 6, leave STOP?.
The query STOP? disappears from the display. The
temperature program is continued.
Note
While STOP? is displayed the temperature program goes on running.
As soon as a section of the temperature program is finished (e.g. after
the end of the heating period or after the end of the reaction time), the
STOP? display is overwritten.
5.4Temperature test program
With the temperature test program, you can check the temperature in
the thermoblock with the aid of an external temperature probe that is
available as an accessory (see chapter 9 A
While the temperature test program is active, the display shows the
current temperature of the thermoblock and at the same time the
measured temperature value of the external temperature probe.
The thermoreactor functions correctly if the temperature of the external
temperature probe does not deviate from the nominal temperature
value by more than 2 °C.
If the deviations from the nominal value are greater, further measures
can be necessary (see chapter 7 W
HATTODOIF...).
CCESSORIES/OPTIONS).

OperationCR 3200
Note
The external temperature probe has the same accuracy as the internal
temperature sensor.
5.4.1Starting the temperature test program
Note
All other temperature programs are blocked while the temperature test
program runs.
1Connect the external temperature probe to the socket at the
thermoreactor (see chapter 3 C
OMMISSIONING).
2Insert the external temperature probe in a cell shaft.
3Switch the thermoreactor on with e.
4Using 8 2, select the temperature test program T.
5Using g start the temperature test program T.
The first display line shows the nominal measuring time and the
temperature of the thermoblock. The second display line shows the
temperature of the external temperature probe. After the nominal
temperature has been reached, the measuring time is counted down in
the second display line.
During the temperature regulation phase, the thermoreactor saves the
measured temperature values of the external temperature probe in a
test report every 60 seconds.
As soon as the temperature test is finished, "PRINT" appears on the
display.
22
You can now output the measuring data of the temperature test to a PC
or printer.
You have the following options now:

Connect the thermoreactor with a printer and download the test
report to the printer (see section 5.4.2).
Leave the temperature test program with g.
The test report in the thermoreactor is erased in any case at the end.
5.4.2Downloading the test report to an external printer/PC
To transmit the temperature test report to a printer or PC, a printer
cable or PC cable is required (see chapter 9 A
CCESSORIES/OPTIONS).
You can record the test report with the aid of a so-called terminal
program on the PC side.
Generally, a terminal program serves to establish a connection to a
meter at a data interface and to communicate with the meter via a
console on the display. A terminal program usually offers the possibility
to save the contents of the console in a text file or print it. If the terminal
program is connected to the thermoreactor, it can receive the
temperature test report and display it on the console.
Sample report
Downloading the test
report
Terminal programs are available by different manufacturers for
different operating systems. The "HyperTerminal" terminal program is
included in Windows (versions 95 to XP). It is in the program menu
under Accessories.
More detailed information can be taken from the user information of the
terminal program.
Precondition:
The temperature test is finished and PRINT is displayed (see page 5-
22).
