When all plumbing and electrical connections are made, slowly open the supply
valve to the inlet tube. Rotate the dial marked M to adjust the flow rate through the
analyzer. The flow rate MUST be stable, and between 10-15 L/hr. Fluctuations in
the flow rate will cause fluctuations in the reading on the display.
Confirm that the site voltage corresponds to that stated on the instrument
identification plate. Turn on power to the transmitter. The transmitter performs a
self-test and displays an initial value.
