6. GASSING THE SENSOR
On Weather Protection Housings, upward pressure on
the gassing nozzle forces the nozzle against the
hydrophobic barrier. Do not rotate the nozzle when fitting
the pipeline as this may cause damage.
Open the valve of the calibration gas test kit and set
the flow rate to 1.5 ± 0.1 litres per minute.
Apply the test gas for a minimum period of 5 minutes
to electrochemical sensors.
Set up the Control System as instructed in the Control
System manual.
On completion, shut off the test gas and disconnect
the calibration gas test kit.
