Safety NoteS
Before using this meter, read all safety information carefully. In this manual the word “WARNING” is used to indicate
conditions or actions that may pose physical hazards to the user. The word “CAUTION” is used to indicate conditions or
actions that may damage this instrument.
WARNING!
This analyzer extracts combustion gases that may be toxic in relatively low concentrations. These gases are exhausted
from the back of the instrument. This instrument must only be used in well-ventilated locations.It must only be used by
trained and competent persons after due consideration of all the potential hazards.

To correctly calculate net temperature and combustion efficiency it is important to have the correct inlet tempera-
ture set. Two methods are available to properly establish the inlet temperature

NOTE: Take care when inserting the temperature
probes as the pins are polarized. Insert with the smaller pin

WARNING!
Turning the pump off while the probe is in the flue
will leave toxic gases inside the analyzer. Once data
has been read, it is advisable to purge the
unit with fresh air as soon as possible. To do this,
with the probe removed from the flue, turn ON the
pump. Always allow the readings to return to zero
