2.4.2 Ambient air temperature plug
The ambient air temperature plug must be connected to the instrument at all time.
If the ambient air temperature plug is not connected, then the unit shows an error message.
The ambient air temperature plug measures the temperature of the air that is used for the
combustion process.
The measured temperature is needed for various calculations.
Connect the plug (4-pos) with the 'air temp' socket of the analyzer.
2.4.3 Gas fitting
The gas hose of the gas-sampling probe must be connected to the gas fitting.
2.4.4 Draft fitting
The draft hose of the gas-sampling probe must be connected to the draft fitting.
2.4.5 LED
The LED shows the power status of the unit.
RED:
battery powered
GREEN:
AC connected and turned off (charging the battery)
YELLOW: AC connected and turned on
2.4.6 Differential pressure fitting (if equipped)
The analyzer is equipped with a third barbed fitting for a differential pressure measurement.
The differential pressure is the pressure that is measured between the 'draft' fitting and this 3
rd
fitting.
Connect a hose to this fitting and insert it into the medium and start the regular draft
measurement. The draft measurement measures now the differential pressure from the
medium to the flue gas, where the gas-sampling probe is inserted.
