16. 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.
16.1. Perform the measurement
Preliminary operation:
To avoid the condensation in the pump, it is necessary to breathe in WITHOUT FILTER fresh air before performing
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.
16.2. 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 auto-zero: remaining time and a progress bar display on the screen. However it is possible to
reach the Bacharach index menu during the auto-zero.
➢
Press
OK
.
➢
Go to
“Bacharach index”
with the keypad.
➢
Press
OK
.
➢
Press
OK
on
“Index 1”
line.
➢
Increment the index from 0 to 9 with the keypad.
➢
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.
16.3. 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.
16.4. 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.
16.5. 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.
