5.5.2 Special programs
5.5.2.1 Vacuum test program
With this vacuum test program, the performance of the vacuum sys-
tem can be automatically tested. For that purpose, the achieved
(minimum) pressure in mbar is measured and indicated. If the
pressure value is below 80 mbar (hPa), the vacuum performance of
the system is adequate.
5.5.2.2 Heater test program
The quality of the heating muffle may be automatically checked by
means of the heater test (duration: approx. 7 min.). The heater test
should only be conducted with the empty firing chamber, since an
object in the chamber (e.g. firing tray) may influence the test result.
Conduct the heater test immediately after switching on the furnace
and before any actual firing procedures. If the furnace is too hot, an
incorrect heating muffle quality will be indicated. If the heating
element quality falls below 50%, replacing the heating element is
recommended.
5.5.2.3 Keypad test
Each time the keypad is pressed, a short beep sounds. The keypad
test can be ended by pressing ESC.
5.5.2.4 Cleaning program
The cleaning program is used to „clean“ the heating muffle
(duration: approx. 17 min.) After a cleaning program, it is
recommended to calibrate the furnace. In case of problems with
discolouration of the ceramic, we recommend replacing the firing
tray material.
5.5.2.5 Dehumidification program
The condensation of water in the insulation of the firing chamber
and the vacuum pump will result in a lower vacuum and thus to
impaired firing results. For that reason, the furnace head should be
kept closed when the furnace is switched off or is below 100 °C, in
order to prevent the absorption of humidity. Start the dehumidifica-
tion program if required (humidity in the insulation).
5.5.3 Information
Once the Information has been
selected via the Settings / Informa-
tion key (78), the first page of the
Information is displayed. The
current page number is shown in
the upper line.
The displayed page (Information) can be changed using the Cursor
keys.
The ESC key can be used to return to the previous screen.
