17. 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.
17.1. Perform the measurement
➢
Connect an ionisation current probe on C1 connection of the analyser.
➢
Turn on the analyser.
Home screen is displayed with measurement menu highlighted.
➢
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 keypad 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.
17.2. 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
“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.
17.3. Add the measurement to a group
The group function has to be activated (see page 18).
Once the measurement is linked to a customer and a boiler, it is possible to add it in a group in the instrument, or create a group:
The analyser proposes to add the measurement to a group.
➢
Go to
YES
and press
OK
.
➢
Go to the required group with the arrows and press
OK
, or create a group (see page 25).
The analyser backs to the measurement screen.
17.4. Print the results
It is possible to print the results on the ticket:
➢
Press the
“Print”
function button.
Results are printed on the ticket.
See page 17 for the printing configuration.
