8.2.4 Taking out the Sample Holder

8.2.4.1 Standard Sample Holder

In order to take the sample out of TTK 600, proceed
as follows:

1. Swich off the heater of CCU 100

2. Open the lid.

3. Disconnect the Pt100 connector.

4. Unscrew the fixing screw of the sample holder

with the supplied Torx screw driver.

5. Take the sample holder carefully out of the fixing

block by gentle pulling on the sheat resistance
temperature sensor (right side) while lifting the
cable of the temperature sensor over the heat-
ing block (left side)

6. Place the sample holder on the corresponding

mount as shown in the following picture.

8.2.4.2 Transmission Sample Holder

CAUTION

Hot surface

During operation and even after switching off the
heater there can be dangerously hot or cold sur-
faces inside the sample chamber. Always check
on the display of CCU 100 that the sample
holder temperature is below 50 °C before you
open the sample chamber and touch any parts
inside.
If CCU 100 shows an error message, use a suit-
able temperature sensor to measure the actual
temperature of the parts inside the sample
chamber. Always switch off the heater before
you take out the sample holder.
