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.
