Our recommendation is to measure the actual inner diameter on the bottom of
the mold and apply the following formula, to obtain the total mass of sample and
flux:
Total mass [g] =
(Mold diameter [mm])²
150
Thus, for a 32-mm inner diameter mold (recommended diameter), we obtain
32² / 150 = 6.827 g, which we can round up to 7 g.
This being said, there are also molds on the market that are very shallow (despite
the thickness of the metal they are made of). Those molds will require less flux to
fill correctly, but using the right amount of releasing agent and properly leveling
the mold are more critical.
Installing the
crucible
When the system prompts you to do so, place the crucible (or other suitable
weighing container) on the crucible holder under the flux chute, and close the
door.
Dispensing the
flux
Fixed-weight mode
This mode will dispense the flux based on the weight selected by the user
(“absolute” mode).
1.
Using the Left/Right arrows, set the needed weight. (In our example, we are
using 8 g of flux)
Select mass:
008.0000 g ~
2.
Then, press Enter. The following screen will appear:
Add the
container
3.
Add the crucible or the container which will be used for the weighing.
4.
Press Enter ; the weighing of the flux will start.
NOTE:
In the case of a non-stable environment, a difficulty to tare could occur.
In that case, cancel the process and restart it.
