Problem
Possible Cause
Corrective Action
Efficiency reading incorrect
NET/GROSS efficiency incorrectly
selected.
Ambient temperature probe not
plugged in to T2.
Incorrect fuel selected.
Select correct efficiency.
Plug ambient probe into T2. See
page 14.
Select the proper fuel for the
appliance being tested. See page 12
or 26.
Readings are erratic when working
on oil fired equipment.
Oil filter not installed or installed
incorrectly.
Make sure the optional sulfur filter
(A773) is installed correctly.
One or all of the following
parameters; Ratio, CO air free,
excess air, and efficiency read and
print dashes.
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 if a
pressure measurement is not being
made this parameter will print as not
being used.
Perform the combustion test and
also connect the manometer and
monitor pressure.
Battery will not charge or hold a
charge.
Defective charger or battery.
Replace the charger or battery.
