Fire hazard when disposing the crucibles/ Risk of burns while touching or
moving the crucible container
Hot parts (crucibles, the container itself) can fall down
− Ignition of tables, floors, or any other surface the hot part falls on
− Ignition of clothes and any other material
• Always wear suitable clothing and gloves when handling the container
• Always make sure that the disposal vessel is clear of any combustible
material and that the vessel itself can withstand the temperatures
introduced by the hot crucibles
• If possible, allow the crucible container and its contents to cool to room
temperature before emptying it, or take appropriate precautions to
dispose of hot crucibles properly.
1. Place an empty crucible on the balance.
2. Tare the balance using the “Tare” button, located on the balance, or
“F6-Tare” button in the “Analysis control” window of the software (F6
on the PC-keyboard).
3. Put about 250 mg coal sample into the crucible.
4. Press the “F4-Balance” button in the ”Analysis control” window of the
software (or F4 on the PC-keyboard) to transfer the weight value from
the balance to the PC. The transfer function is performed regardless
how often the button is pressed. This enables a correction of any
falsely entered weight.
5. Enter the sample ID into the corresponding input field of the “Analysis
control” window of the software. This step is optional. If no sample ID
is required, the entry may be omitted.
6. Press the “F7-Add” button in the “Loader” window. The sample weight
and sample ID are transferred to the loader stack and memorized
there.
7. Take the crucible from the balance and put it on the loader, on the first
tray before the pick-up position.
8. Mark the “F8-Run/Stop” checkbox to start the analysis.
The analysis procedure begins. From now on, no operator intervention is required. The furnace
is opened automatically, the crucible of the previous analysis is picked up from the pedestal and
disposed, and the crucible is taken from the loader and put on the pedestal for analysis. The
furnace closes. At the end of analysis, the results are displayed on the PC-screen and saved in
the database of the software.
A series of analyses can be run with the CS-580A (Helios) analyzer. To do this, repeat steps 1
to 7 for every sample in the series, while each crucible is placed as next after the last one
placed on the loader. This can be done at any time, with or without running analyses.
When putting the samples on the loader, the order of positioning the crucibles on the trays must
be respected, i.e. the crucibles must be placed on the loader exactly in the same order in which
they are weighed and memorized in the loader stack. It is allowed to leave one or more empty
trays on the loader, for example in order to separate groups of crucibles carrying the same
sample material or a calibration standard etc.
