62 . TGA 8000 Installation and Hardware Guide
Adjusting the Furnace
When your TGA 8000 with standard furnace and
no autosampler
is installed by a service
engineer, he performs a series of adjustments in order to optimize its performance. If you
need to remove the furnace and/or furnace tube, perhaps to clean it, you will have to perform
these steps to ensure proper operation of the instrument. These include:
•
Adjusting the Height of the Furnace
•
Adjusting the Balance Mechanism
•
Adjusting the Height of the Furnace
The height of the furnace is pre-set at the factory therefore no adjustment should be
required. However, if a thermocouple is replaced then the below procedure must be
followed:
1.
The sample pan should still be on the hangdown wire. If not, place a pan on the end
of the hangdown wire.
2.
Click Raise Furnace button on the Pyris Control Panel.
3.
Check the position of the stirrup with respect to the tip of the thermocouple.
4.
Adjust the height of the furnace using the furnace adjust height knob located below
the furnace adjustment ring. Turn the knob counterclockwise to raise the furnace
and clockwise the lower the furnace.
5.
Raise the furnace using the knurl knob adjustment until the pan touches the tip of
the thermocouple, this is done by observing the weight status in the status panel.
When you see a weight change…
•
Turn the furnace knob adjustment 3 full turns CCW (this will lower the
furnace ~3mm - each turn is 1 mm).
•
Then turn the knob 2 full turns CW. The result will be the thermocouple will
be about 1 mm below the sample pan.
CAUTION:
Make sure that the sample pan hangs in the center of the furnace. It is
important that the sample pan does not touch the side wall of the furnace or the tip
of the thermocouple.
ATTENTION:
Assurez-vous que la casserole d'échantillonnage est suspendue au
centre du four. Il est important que le récipient d'échantillon ne touche pas la paroi
latérale du four ou la pointe du thermocouple.
