How the Protec P3000 Works
2.3.3 Built-in PRO-Check reference leak
A built-in PRO-Check reference leak is available for all Protec P3000. The PRO-
Check reference leak can be used for verifying the correct functioning of the Protec
P3000 including the correct calibration and can also be used for re-calibrating the
Protec P3000 if necessary.
The PRO-Check reference leak is inserted in the front of the housing. Insertion of the
sniffer tip into the cone-shaped test leak opening is automatically detected via a light
barrier.
