5.5.5.2 Heater test
The quality of the heating muffle
may be automatically checked by
means of the heater test (dura-
tion: approximately 7 minutes).
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.
5.5.5.3 Cleaning program
The cleaning program is used to "clean" the heating muffle
(duration: approx. 17 minutes). 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
table or the firing tray material.
5.5.5.4 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, in order to prevent
the absorption of humidity. Start the dehumidification program if
required (humidity in the insulation).
5.5.5.5 Keypad test
Each time the keypad is pressed, a short beep sounds. The keypad
test can be ended by pressing ESC.
5.5.5.6 Display test (page 2/2)
Two different "chequer-board patterns" are alternately shown on the
entire display. This allows the visual check of each individual pixel.
The display test can be ended by pressing ESC.
