5.5.6.1 Tests (test programs)
– Vacuum test program
With the vacuum test program, the performance of the vacuum system of the furnace 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.
– Heater test
The quality of the heating muffle can be automatically checked by means of the heater test (duration: approximately
7 minutes). The heating muffle test should only be conducted with the firing chamber empty, since any additional item
in the firing chamber (e.g. firing tray) influences the result. Conduct the heater test immediately after switching the
furnace on and before any actual firing procedures are conducted. If the furnace is too hot, an incorrect heating muffle
quality will be indicated. If the quality of the heating element drops below 50%, changing the heating element is
strongly recommended.
– Keypad / touch test
Each time the keypad or the touch buttons are pressed, a short acoustic signal sounds to confirm its function.
– Display test
Two different chequerboard patterns are alternately shown in the entire display. Every individual pixel can be visually
checked.
–
OSD test
The OSD test checks the LEDs of the Optical Status Display. During the test, the OSD lights up in different colours.
– Press drive test
This test automatically checks the functioning of the press drive.
5.5.6.2 Error table
