2.4 SYSTEM CONNECTIONS

2.4.1 Probe

The gas-sampling probe plug and hose has to be connected to the analyzer before it can be
turned on and must stay connected during the whole measurement.
If the gas-sampling probe is not connected, then the analyzer cannot perform an accurate
calibration and an error message will be displayed.

Type S (if equipped with soot measurement)

The probe S has two hoses. One for the flue gas measurement and one for the draft
measurement. Both hoses must be connected to their fittings at all time.
It also has a connection line to connect the thermocouple with the analyzer.

a) Thermocouple

- Connect the thermocouple plug (5-pos) with the

'flue gas temp' socket of the analyzer

b) Flue gas

- Connect the hose, which has the condensation trap

inline to the barbed fitting 'gas input'

c) Draft

- Connect the second hose to the barbed fitting

'draft'

Type E

The probe E has one hose for the flue gas measurement and the draft measurement.
It also has a connection line to connect the thermocouple with the analyzer.

a) Thermocouple

- Connect the thermocouple plug (5-pos) with the

'flue gas temp' socket of the analyzer

b) Flue gas

- Connect the hose to the barbed fitting 'gas input'

The hose must be connected to the 'gas input' fitting for the flue gas measurement.
The hose must be connected to the 'draft' fitting only for the draft measurement and it must be
connected back to the 'gas input' fitting after the draft measurement is completed.

Type C (if equipped)

The probe C is a ceramic probe with a Pt-RhPt thermocouple and it is used for high
temperatures. The temperature range is 302



F-2732



F / 150



C-1500



C.

It has the same connections as the probe E.
