5.5 Controlling the Compressed-Air
Cooling
The cooling device is automatically turned on and
off by CCU 100 whenever it is needed.
There are two modes available:
1. cOFF: An operation of the DHS 1100 without a
dome is possible below 200 °C requiring that the
compressed-air cooling is switched off. Exceed-
ing 200 °C the CCU 100 automatically switches
on the compressed-air cooling.
2. cON: Compressed-air cooling is switched on
under 200 °C when above dSP +1 °C and cool-
ing to a lower set point temperature. This mode
allows faster cooling between 200 °C and room
temperature compared to the cOFF cooling
mode.
5.6 Manual Control of CCU 100
Manual operation of DHS 1100 is done with the
keys on the front panel of CCU 100. Proceed as fol-
lows to heat or cool the sample to the desired tem-
perature:
1. Make sure that the heater is switched on.
2. Set the desired heating/cooling rate on the
parameter page of CCU 100. (See
).
3. Push the scroll button one time (SP LED green)
and set the desired target temperature by using
the UP/DOWN buttons.
4. Wait until the displayed sample plate tempera-
ture has reached the target value.
TIP:
If you have chosen a large heating/cooling
rate, wait 1 minute before you start the X-ray scan to
make sure the sample surface has reached a con-
stant temperature.
5.7 Remote Control of CCU 100
Usually CCU 100 is integrated in the software that
controls the X-ray diffractometer. For more informa-
tion about controlling DHS 1100, read the instruc-
tion manual of the diffractometer control software.
Alternatively it is also possible to remote control the
instrument with the delivered Nambicon software
(Non-AMBIent-CONtrol) by Anton Paar GmbH. For
further information see the corresponding manual of
the Nambicon software.
The NAMBICON software is included in the delivery
of the instrument. Please follow the instructions in
the manual of the software for corresponding instal-
lation and use.
