Operating Information
5.2 In-process Exhaust Air
Analysis
Danger of burns! After connecting the power
supply, the housing of the BioPAT
®
Xgas heats
up due to warming!
t
Do not touch it any longer or only when
wearing gloves.
t
Compare the process conditions with the bio-
reactor specifications in the “Technical Data“.
Do not connect the device for gases or under
process and ambient conditions it is not
designed for.
5.2.1 Switching on the BioPAT
®
Xgas
After initial start-up and when the power supply is
disconnected, the BioPAT
®
Xgas requires a warm-
ing phase of about 1 h until it can operate within
the limits of the measuring range, see “Technical
Data“. LEDs on the device display the operation
status. Displayed measurements indicate the zero
current conducted during warm-up, not the actu-
ally measured gas concentrations.
t
The BioPAT
®
Xgas is activated when the
bioreactor is switched on or when the power
supply is connected. Wait for the device to
warm up (approx. 1 h). The LED rings around
the buttons light up and indicate the sensor
status. During the warm-up phase, the sensor
supplies a current signal of approx. 2.3 mA
