Overheating of the HTFr
Using the wrong switch setting for cooling down
−
If the switch on the HTFr is set to position 0 before the furnace has cooled
down sufficiently, this may result in overheating and the triggering of a
safe state. The cooling cannot take place on setting 0 because the HTFr
is without power on setting 0, and the fan is therefore also turned off. The
HTFr must be set to level 1 to cool down.
•
Set the HTFr to position 1 to cool down.
•
Only set the HTFr to position 1 once the machine has cooled down
sufficiently.
The machine is operated using the ELEMENTS software. The program is delivered on a USB
stick and is already installed on the PC if this has been ordered.
The following conditions must be met
before
operating the machine to analyse samples:
•
The machine has been commissioned, see
”.
See the program manual for details of the ELEMENTS software.
Proceed as follows to perform analyses:
1. Ensure that the PC has been switched on and the ELEMENTS software started (see
”).
2.
Open the “Analyses and results” window.
Create a new analysis and select a suitable application.
(see Elements Software
“Application”)
3. Prepare a crucible or dish with sample material.
Only use crucibles (Part number 90148 or 90149) and dishes (e.g. Part number 90160)
from Eltra GmbH.
4. Use the automatic transfer of the sample weight from the balance to the PC or enter the
sample weight manually. Give a name for the sample in the “ID” box.
5. If you wish to analyse the sample using the induction furnace of the analyzer, place the
crucible into the crucible holder using crucible tongs (see Pos. (
9
) in “
Ensure that the main switch of the analyzer is set to Position 2.
6. If you wish to analyse the sample using the resistance furnace of the HTFr, place the dish in
front of the furnace entrance using crucible tongs (see Pos. (
6
) in “
Ensure that the main switch of the HTFr is set to Position 2 and that the furnace has
reached the set point temperature (“
7. To start the analysis, ensure that the desired analysis has been marked then press F5 or
click on the green arrow in the ELEMENTS software.
When analyzing the sample with the HTFr, slowly push the boat into the oven as soon as
the green signal light on the HTFr resistance oven illuminates.
The analysis will be performed.
Analysis with the HTFr resistance furnace:
As soon as the base lines are stable, you will be prompted by the ELEMENTS software and by
the illumination of the green LED on the HTFr (see Pos. (
3
) in
“) to slide the boat into the
furnace.
Only use the supplied boat slider (Part number 36216-2001) for this and slide the boat until the
handle of the boat slider hits the balcony of the furnace.
