Compare the darkening of the filter with the smoke index table. The smoke index found does not exceed the ones
defined by the current normative.
We suggested to use a retaining cone during gas sampling.

7.4.1 Smoke Index data input
Before inputting the data, you have to execute the smoke index measurements. You can input up to 3 values; the
analyser will do the average calculations.
ƒ
The smoke measurement requires the instrument in normal operating conditions indicating one of the measured or
calculated parameters. Press [

7.5 Combustion Air Temperature
(option)
It is important to measure the true combustion air temperature to have a correct boiler
efficiency calculations. The 3000-4000 series
have an auxiliary Rtd input to measure
simultaneously the air temperature. A Pt100 with a 6 meters long cable can be connected on
the right side of the analyzer.
Insert the Rtd inside the air combustion aspiration tube near the boiler.
Follow the standard procedure to make measurements. The instrument
will show the
temperature on the display and the efficiency will be calculated using this value. If no
external Rtd is connected, the analyzer will measure the instrument temperature (ambient)
using the internal sensor.
7.6 Flow/Return Temperature measurement
Connect the thermocouple type K on the bottom of the instrument (the same connector used for gas temperature). If the
temperature measurement is made using the contact method on the external side of the flow and return water pipe. In
this case, we suggest to use an arch type thermocouple.
