12. Perform a pressure measurement
The draft measurement allows to check if the flue of the boiler correctly clears flue gas caused by the combustion.
12.1. Perform the measurement
➢
Connect the flue gas probe on the analyser.
➢
Turn on the analyser.
➢
Go to the
“Measurement”
menu with the keypad then press
OK
.
The analyser performs the gas autozero: remaining time and a progress bar display on the screen.
➢
Go to
“Pressure”
with the keypad then press
OK.
➢
Go to
“Draught pressure”
with the keypad then press
OK.
Measurement launches and the analyser displays the draft.
12.2. Perform a differential pressure measurement
➢
Connect the flue gas probe on the analyser.
➢
Turn on the analyser
➢
Go to the
“Measurement”
menu with the keypad then press
OK
.
The analyser performs the gas auto-zero: remaining time and a progress bar display on the screen. The pressure
measurement remains possible.
➢
Go to
“Pressure”
with the keypad then press
OK
.
➢
Go to
“Diff. Press.”
with the keypad then press
OK
.
➢
Press
“Auto-zero”
.
Measurement launches and the analyser displays the differential pressure.
12.3. Perform a flue gas velocity measurement
➢
Connect the flue gas probe on the analyser.
➢
Turn on the analyser.
➢
Go to the
“Measurement”
menu with the keypad then press
OK
.
The analyser performs the autozero: remaining time and a progress bar display on the screen.
➢
Go to
“Pressure”
with the keypad then press
OK
.
➢
Go to
“Flue gas velocity”
with the keypad then press
OK
.
The measurement launches and the analyser displays the differential pressure.
12.4. Link the measurement to a customer
When the measurement has been performed, it is possible to link it to a customer registered in the analyser or to a customer
unregistered in the analyser that must be created.
➢
Press the
“Save”
function button.
The analyser displays the list of recorded customers.
➢
Select a customer with up and down arrows then press
OK
or create a customer (see page 23) then select it.
The analyser displays the list of available boilers.
➢
Select the boiler with up and down arrows then press
OK
or create a boiler (see page 24) then select it.
The analyser backs to the measurement screen.
