15. Perform a measurement of opacity
It is possible to enter in the analyser from 1 to 3 opacity indexes performed thanks to opacity pump available as option.
The opacity index consists of the measurement of solid waste of combustion in the flue with a pump and a filter of measurement. The filter coloration
is compared with a table reference composed by 10 greyed areas numbered from 0 to 9.
15.1. Perform the measurement
Preliminary operation :
To avoid the condensation in the pump, it is necessary to breathe in WITHOUT FILTER fresh air before perform a measurement.
➢
Put the paper filter in the pump.
➢
Pump out flue gas in the middle of the flue.
The necessary gas volume for a measurement of opacity corresponds to about 10 pump aspirations.
➢
Compare the filter clogging to the reference table to determine the opacity index.
➢
Make the same operation several times if necessary, replace the filter each time.
15.2. Enter the indexes in the analyser
When the measurement of opacity has been performed, enter the opacity indexes in the analyser :
➢
Turn on the analyser.
The analyser performs the autozero : remaining time and a progress bar display on the screen. However it is possible to reach the
Bacharach index menu during the autozero.
➢
Press
OK
.
➢
Go to
“Bacharach index”
with the rotative button.
➢
Press
OK
.
➢
Press
OK
on “
Index 1”
line.
➢
Increment the index from 0 to 9 with the rotative button.
➢
Press
OK
.
➢
Repeat the procedure for 2 and 3 indexes.
The analyser indicates the opacity indexes average on
“Average”
line at the bottom of the screen.
15.3. Link the index to a customer
When the average 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 about the opacity.
15.4. Print the index 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
