Before using the test fixture, the technician should first be familiar with the operation of
Detcon FP series combustible gas sensors. Review the applicable sensor instruction
manual(s) for detailed operating instructions.
The test fixture is designed to verify performance of the Detcon FP series transmitters

assembly.

Plugging more than one transmitter in the test fixture at the same time (P1 and P2) will
cause erroneous readings.
