Problem Possible Cause Corrective Action
Efficiency reading incorrect NET efficiency selected.
Ambient temperature probe
not plugged in to T2.
Incorrect fuel selected.
Select GROSS efficiency.
See section 5.3.
Plug ambient probe into T2.
See section 5.2.
Select the proper fuel for the
equipment being tested. See
section 4.1.
Readings are erratic when
working on oil fired equip-
ment. Oil filter not installed or
installed incorrectly. Make sure the optional oil fil-
ter (A773) is installed. See
Appendix D.
One or all of the following
parameters; NOx, Ratio, CO
air free, excess air, and effi-
ciency read and print dash-
es. Measured values are such
that the calculated values of
these parameters are out of
range. Redo combustion test. Since
these are calculated values,
the measure values must be
within certain levels for these
to display. If the measured
oxygen level is above 19.9%
these parameters won’t
read.
These parameters might not
display or be applicable in
some tests.
Pressure prints as “N/A” on
my combustion analysis print
out. During combustion analysis
the pressure function is dis-
abled. The manometer fea-
ture is a separate function
and must be printed sepa-
rately. Perform the combustion test
and then perform a pressure
test. Save each test in a dif-
ferent location and print
each test.
Battery will not charge or
hold a charge. Defective charger or battery. Replace the charger or bat-
tery.
Send to TPI for service.
Beeping noise heard during
charging. Defect in charging circuit or
shorted battery. Disconnect from the charger
and contact TPI at 800-368-
5719.
Analyzer won’t turn off Oxygen and/or carbon
monoxide levels outside lim-
its. Allow the analyzer to purge
longer.

Lo
bat
Low battery. Battery needs to be charged. Charge or replace battery.
oFL
Overflow indication. The tem-
perature or pressure being
measured is outside the
maximum measurement
capability. Temperature or pressure
being measured is too high
or low. Remove temperature or
pressure source.
