Using The Particulate Matter Probe - TESTO 380 Instruction Manual

5.1.5.

Using the particulate matter probe

CAUTION
Hot probe shaft due to automatic heat-up!
Risk of burns!
> Do not touch the probe shaft.
ATTENTION
Backflow of condensate from the crude gas tube!
Clogging of the rotation discs and damage to the testo 380.
> Before removing the particulate matter probe from the flue gas
duct, remove the crude gas tube from the particulate matter
probe connection and dispose of the condensate in a suitable
container.
Checking the thermocouple
The thermocouple of the particulate matter probe must not lie
against the probe cage.
> Check before use. Bend the thermocouple back if necessary.
Aligning the particulate matter probe
> Turn the particulate matter probe to align the thermocouple
so that it is freely exposed to the flue gas flow.
> Align the particulate matter probe in the flue gas duct so that
the tip of the particulate matter probe is in the centre of flow
(area of the highest flue gas temperature).
