5.4.6.1 Tests (test programs)
– Vacuum pump test program
With the vacuum pump test program, the vacuum performance and tightness of the furnace vacuum system 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.
– Heating muffle test
The quality of the heating muffle may be automatically checked by means of the heater test (duration: approximately
7 minutes). The heater test should only be conducted with the firing chamber empty, 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 are conducted. 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.
– Keypad / touch test
Each time the keypad or the touch buttons are pressed, a short acoustic signal sounds to confirm their function.
– Display test
Two different chequerboard patterns are alternately shown in the entire display. Every individual pixel can be visually
checked.
– OSD test
This test is used to check the LEDs of the Optical Status Display. For that purpose, the OSD alternately flashes in
different colours.
– IRT test
Fully automated test infrared camera function.
