»!!! MV low« alarm is activated until the measured value has
risen above the lower alarm limit.

Gas supply
● Screw the connecting hoses for medical air and oxygen to
the back panel of Evita 2 dura and insert their probes into
the terminal units.
The compressed gases must be dry and free from dust and
oil. Gas pressure must be 3 to 6 bar.
Other equipment, e.g. printers, may only be connected to
the COM ports if Evita 2 dura is connected to the mains
power supply via a mains power cable or if it has been
earthed via the earth connection on the back of the unit.
Electric power may pose a hazard in all other cases.
