7.6 Connecting the Gas Sample Pipe
To take a gas sample first connect the plastic sample pipe fitted with the filter to the 'Gas In' port at the top of the
instrument.
To do this, push the metal latch down then insert the connector at the end of the sample pipe. The port will lock the
pipe in place and prevent it from being pulled out accidentally; it can be removed by pushing the metal latch down
and pulling out the sample pipe.
Connect the open end of the gas flow tube to the gas tap or sample point on the pipework to be checked.
Open the gas tap and press the Right Soft Key to begin sampling.
