Preparing Delta T determination
Figure 6 shows in detail how the accessories for determining Delta T are
mounted. Proceed as follows:
1
Prepare reaction vessel cover
￭ Mount the air tube on the reaction vessel cover (see "Mount the
reaction vessel cover", page 15).
￭ Clamp the first spacer at a distance of approx. 12 cm from the
lower end onto the air tube.
￭ Clamp the second spacer at a distance of approx. 5 cm from the
lower end onto the air tube.
￭ Insert the temperature sensor from above into the temperature
sensor opening of the reaction vessel cover and fasten it in the
corresponding openings of the spacers.
2
Prepare reaction vessel
￭ Fill the reaction vessel with 5 g silicone oil (e.g. FLUKA 85409).
￭ Place the reaction vessel cover with the temperature sensor on
the reaction vessel.
￭ Push the temperature sensor fully downwards (the sensor must be
on the vessel base).
3
Insert and connect reaction vessel
￭ Insert the reaction vessel with the mounted reaction vessel cover
in channel 2 or 3 of the required heating block.
￭ Screw the one end of the FEP tubing 250 mm onto the thread
adapter M8 / M6 of the reaction vessel cover.
￭ Screw the other end of the FEP tubing onto the corresponding
connector (3-3) of the Rancimat.
4
Set method parameters
Note
Create a unique method for both blocks, so that you can sepa-
rately enter the temperature correction for both blocks.
￭ In the Control window, select the required method for the
heating block for which the temperature correction Delta T is to
be determined (see "Select method", page 81).
