3. Starting up and operation
3.1 Preparing for use
Make sure that all components are in good condition e.g.:
no condensate in the gas conditioner
the filter fleece and the filter disks are clean
the gas hoses are in good condition
the probe is free from defects
Connect the gas conditioner with the gas inlet of the MSI EM200plus. Never forget to use
the gas conditioner to protect the instrument, otherwise pump and sensors could be dam-
aged.
Verify that fresh air will be sucked through the gas conditioner before switching on, be-
cause the zero signals of the sensors are checked with fresh air.

3.2.1 Switching on / off the MSI EM200plus

battery symbols
The battery symbols show the batteries capacity. The bar represents the progress of the run
in of the el.-chem. sensors and the progress of the check function. In addition the time, the
software version and a selected operator are shown.
The time of the system check is dependent on the stabilisation time of the O2 sensor. De-
pending on the switch-off length and time the stabilisation time will be at least 30 seconds,
possibly it can last more than 10 minutes. If errors have been detected, error messages will
be generated and displayed.
Switch off
the instrument by using the switch off function in the menu “selection of functions”
or by pushing “F” until the display reads “Switch off” (approx. > 3 sec). Is the O

value less
than 20 % or the CO value higher than 10 ppm during switching off, the pump will run on for
2 minutes. With a longer touch on the “F” button the pump will be switched off at once.
