4.6 Regular Checks During Sampling
Care must be taken at all times not to exceed the analysers operating specifications, in
particular ensure the following :-
• Do not exceed the maximum temperature of the flue probe.
• The analyser internal temperature does not exceed normal operating range, typically 0-
40
°C.
• DO NOT PLACE THE INSTRUMENT ON A HOT SURFACE.
• The water trap is vertical at all times. Water condenses in the probe line and can quickly
fill the water trap when the probe is moved. Take care and watch the water trap closely.
• The in-line particle filter is clean and does not become blocked.
4.7 Normal Shutdown Sequence
DO THIS EVERY TIME YOU USE THE ANALYSER
Remove the probe from the flue - TAKE CARE ! THE PROBE WILL BE HOT - and
allow it to cool naturally. Do not immerse the probe in water as this will be drawn into the
analyser and damage the pump and sensors.
Once the probe is removed from the flue press and the analyser will count down from 30
to switch off.
OFF 30
MENU TO ESCAPE
If you have not finished but press by mistake, you can press to return to normal
operation and not switch OFF.
