The Microx Online will provide reliable and fault free service when given
regular maintenance and calibrations.
5.1 Routine Inspection and Maintenance
It is advisable to periodically inspect the installation:
Clean gas detector head using a clean DAMP cloth.
Inspect the sensor and ensure it is sound and the sensor-housing
aperture is not obstructed (where applicable).
The maximum time interval between routine inspections should be assessed
by the calibrating personnel and will depend upon the environment in which
the equipment is installed.
5.2 Sensor Replacement
This procedure requires powering off the Instrument.
Open the instrument door.
Disconnect the oxygen Sensor connection cable from the terminals on the
internal board .
Next, unscrew the hexagon compression fitting nut which secures the Oxygen
Sensor.
Withdraw the Sensor. Replacement is a reversal of the above procedure.
Perform a calibration as described in the relevant sections of this manual.
