8.1.5 End of the Analysis
-
At the end of the combustion analysis, carefully remove the sample probe and remote air temperature probe, if
used, from their relative ducts, taking care not to get burnt.
-
Switch off the instrument.
Then, proceed to turn off the instrument.
The instrument execute a cleaning cycle, according to what’s set in the menu
“Configuration→Analysis→Autozero→Purging”, during which the pump sucks clean air until reducing the
concentration of CO. The instrument automatically turns off within max. 10 minutes.
Note: It is always advisable to purge the instrument with clean air for at least 5 - 10 minutes before turning it
off.
Gas sampling probe cleaning
-
When you finish using the sample probe clean it thoroughly as described below before returning it to its case:
- Disconnect the sample probe from the instrument and from the water trap (Fig. a-b) then blow a jet of clean air
into the hose of the probe (refer to Fig. b) to remove any residual condensate that may have formed within.
Fig. a
WHEN THE GAS SAMPLING PROBE IS TAKEN OUT OF THE STACK, THE FORMATION OF
SOME CONDENSATION IN THE PROBE TUBE AND IN THE ANTI-
MAY OCCUR.
IT IS ADVISED TO ACCURATELY CLEAN EVERY PART BEFORE PUTTING AWAY THE
PROBE AND THE ANTI-CONDENSATION TRAP IN THE CASE.
IN ORDER NOT TO DAMAGE THE CASE MAKE SURE THAT THE METALLIC PROBE PIPE IS
AT AN INFERIOR TEMPERATURE THAN 60°C.
