Meaning of the degasser LEDs
Two LEDs at the front of the degasser in the ASM 2.1L inform about the
operation condition of the degasser.
Yellow LED
Shows that the vacuum has not yet reached the work range. Usually,
the yellow LED lights up when the device is switched on and goes out
as soon as the vacuum drops below 130 mbar.
Green LED
Shows that the vacuum is within the work range. Usually this indicator
lights up when the vacuum has been generated and stays on as long as
the degasser is in use.
