8 Operation
The HTK 1200N allows for measurements under
various atmospheric conditions (air, vacuum, inert
gas) in the temperature range from room tempera-
ture to 1200 °C.
8.1 Before Turning on Power
8.2 Operation under Air Atmosphere
8.2.1 Operation at Room Temperature
Operation is performed in the same way as with the
standard sample holder. No special precautions
have to be taken.
8.2.2 Operation as Heating Chamber
Operation is performed in the same way as with the
standard sample holder.
The CCU 1000 Combined Control Unit by Anton
Paar GmbH is available for the HTK 1200N. For de-
tailed ordering information, see
. The
temperature control unit is used to control the sam-
ple temperature by means of the chamber’s heating
system as well as the thermocouple.
Keep the following sequence, when starting the op-
eration of the HTK 1200N at high temperatures:
1. Mount the sample and insert the sample holder
flange into the chamber, as described in
and
2. Switch on the cooling water circuit.
3. Switch on the temperature controller and set the
required sample temperature.
NOTICE
Risk of damage
Make sure that the HTK 1200N is installed
according to the instructions in
.
Take care that the cooling water hoses con-
nected to the inlet/outlet nozzles are protected
against unintentional disconnection.
- for detailed information on
the requirements for cooling water quality.
Check the flow controller of the CCU 1000 peri-
odically for proper functioning.
Only turn on the mains supply of the CCU 1000
Combined Control Unit, when the instrument is
fully installed.
Always operate the HTK 1200N with the cooling
water circuit on. This is absolutely necessary to
avoid effects of the working temperature on the
goniometer.
Do not exceed the maximum permissible pres-
sure of 4 bar to prevent bursting of the hoses.
Make sure that the alignment slit is demounted
from the sample holder before operating the
chamber.
CAUTION
Hot surface
During operation and even after turning off the
instrument, temperatures at the sample holder
can reach up to 1200 °C. Make sure that the
sample holder is at room temperature before
handling it.
NOTICE
Risk of damage
Check the chemical resistance of the materials
in the HTK 1200N BEFORE the experiment.
