Comb.
analysis
The user, with this menu, can set the different reference parameters of the instrument to
perform the combustion analysis.
Draft
The DRAFT menu gives access to the stack draft measurement.
NOTE: The measurement may not be accurate due to condensation inside the gas
probe. Should you notice an inaccurate or unstable reading on the instrument, it is
advisable to disconnect the gas probe from the instrument itself, and purge pipes by
blowing with a compressor. In order to be sure there is no humidity, it is suggested to
perform the measurement by means of the transparent rubber pipe supplied on issue.
CO air
This type of analysis lets the user measure the CO value present in the environment, with the
scope of checking the personal safety conditions of a specific working environment. The
instrument leaves our factory with the following pre-set threshold values:
COmax
: 35 ppm Recommended exposure limit (REL) stipulated by the National Institute for
Occupational Safety and Health (NIOSH), equivalent to 40 mg/m
3
and calculated
as an 8-hour Time-Weighted Average (TWA).
It is compulsory to perform the autozero in the clean air, so that the
ambient CO measurement is correct. It is advisable to turn on the
instrument and wait for the autozero completion outside the area where
the test is being performed.
Pressure
Through the use of the external flexible pipe made in RAUCLAIR (supplied) is possible to
measure a pressure value within the range stated in the technical features (connect the pipe
to P+ input).
