W ARN I N G S !
For safety reasons, the Leakator 10 must only be operated
and serviced byqualified personnel.Read and understand
the contents of this instruction manual before operating
or servicing.
To prevent ignition of a hazardous atmosphere, do not
perform any maintenance work, such as replacing the in-

The sensor becomes less sensitive
after being exposed to an excessive amount of
gas. Therefore, after testing the instrument as
described above, leave it on for several minutes
to restabilize the sensor.

5.1 R e p laci ng th e Se n s o r
Note that If the resistor leads are cut
too short, the instrument may not function.
Notice that
the sensor’s six pins and the socket are symmetrical and not
keyed, thus permitting the sensor to be plugged in two ways.
The socket, however, is wired so that it doesn’t matter which
way the sensor is installed.
