1.2 Inlet/exhaust connections

I-Test has three gas ports: the test gas is connected to inlet

, the purge inlet

should be

connected to fresh air, and the gas exhaust outlet

should be connected to a suitable length of pipe

that vents to outside air.

Gas cylinders must be used with demand flow regulators.

To ensure accurate bump testing and calibration the purge inlet must be connected to

fresh air.
