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.
