If the probe is installed in a pressurized chamber, always make sure that
the pressure of the chamber is equalized with the ambient pressure prior
to removing the probe. When the probe is pulled out for maintenance,
cap the hole with a capped nut. This way, the process can be running
although the probe is not in place. For ISO threaded connections, a plug
(Vaisala order code 218773) is available.
