16. Perform a measurement of ionisation current
The measurement of ionisation current allows to check the presence of the flame. In standard operation, the ionisation probe produces a currant of a
few µA or a few dozen of µA. In case of lack of flame, this current is not present anymore (measurement : 0 µA), the safety equipments of the boiler
cut off the power supply.
16.1. Perform the measurement
➢
Connect a ionisation current probe on C1 connection of the analyser.
➢
Turn on the analyser.
Home screen is displayed with measurement menu at the forefront.
➢
Press
OK
.
The analyser performs the autozero : remaining time and a progress bar display on the screen. However it is possible to reach the
ionisation current menu during the autozero.
➢
Go to
“Ionisation current”
with the rotative button then press
OK
.
➢
Connect the ends of the probe on the boiler.
The measured ionisation current is displayed on the analyser. This value must be equal to several dozen of µA.
16.2. 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 function key
to save.
The analyser displays the list of registered customers.
➢
Select a customer with the rotative button then press
OK
or create a new customer (see page 20) then select it.
The analyser displays the
list of available boilers.
➢
Select the boiler with the rotative button then press
OK
or create a boiler (see page 21) then select it.
The analyser backs to the screen of ionisation current measurement.
16.3. Print the measurement on the ticket
At the end of the measurement, it is possible to print it on the ticket.
➢
Press the function key to print it.
The value is printed on the ticket
