4.5 Taking a Pressure Reading
With the optional pressure module fitted a flue draught measurement can be made at
any time.
Connect the standard probe to the appropriate pressure sensor inlet and place the
probe in the flue.
The pressure reading will be displayed :-
CO/CO2 R . . 0.0001
P INDEX % . . . 0.01
XAIR % . . . 0.0
Prs mbar 0.00
NOTE: Care must be taken to connect the probe to the correct port as the pressure
will be displayed in reverse i.e. a positive pressure rather than negative
draught.
To perform a combustion test and display draught pressure at the same time a special
probe is required. Contact Kane International or Authorised Distributor for details.
Two pressure ports are provided on the instrument for use with a Pitot tube. Contact
Kane International Ltd. for details of this probe and its availability.
4.6 Regular Checks During Sampling
Care must be taken at all times not to exceed the analyser’s operating specification. In
particular ensure the following :-
• Do not exceed the maximum temperature of the flue probe.
• The analyser’s internal temperature does not exceed normal operating range,
typically 0-40 °C.
• DO NOT PLACE THE ANALYSER ON A HOT SURFACE.
• The water trap is vertical at all times. Water condenses in the probe line and can
quickly fill the water trap when the probe is moved. Take care and watch the water
trap closely.
• The in-line particle filter is clean and does not become blocked.
