When should I use the optional A773 oil filter?
Always use an A773 sulfur filter when working on oil
fuel applications. It will eliminate erratic readings due to
sulfur being present. Do not use an A773 filter when
measuring NOX
Tech Tip:
tion efficiency when working with modern gas fired
equipment is through gas manifold pressure adjustment.
Confirm manifold pressures are within manufacturers
specifications prior to performing a combustion test.
Once manifold pressures are within limits a combustion
test can be performed to provide information regarding
any adjustments that may be needed.
Should I set my analyzer to net or gross efficiency?
Gross efficiency is the correct choice for applications in
the United States.
Can I use any of the TPI analyzers to test for the
presence of combustible gas in the flue?
Yes, the 712 has the ability to test for combustible
gases in the flue.
Can I log and send test data to a computer?
Yes, the 712 and 714 have the ability to communicate to
a computer by using the optional A767 infrared adapter.
Can I test for CO in ambient air?
Yes, the 707, 708, 709, 712, and 714 can all test for
carbon monoxide in ambient air.
Do any of the TPI analyzers have a built in manometer?
Yes, the 709, 712, and 714 have built in
differential manometers.
Pressure applied to the (-) port is subtracted from the
pressure applied to the (+) port. Examples of pressures
being measured:
(+) port = 10"H2O, (-) port = Not Connected, Displayed
reading =10"H2O
(+) port = 10"H2O, (-) port = 5"H2O, Displayed reading =
5"H2O
(+) port = Not Connected, (-) port = 10"H2O, Displayed
reading = -10"H2O
