During the needle
adjustment,
this
message
could appear without the
snifffer probe
necessarily
being clogged: this is why the needle length
is so important.
For more details, please
consult
the
user’s
manual delivered with your
leak detector.
Advice:
Block
the sniffer probe end from time to time with a finger to check
that the helium signal goes down. If not, the sniffer probe may be
clogged.
