Why is there no inlet pressure in my Witschi ProofMaster Laboratory Equipment?

The inlet pressure may be too low. In this case, check the compressor's output pressure. Also, the maximum vacuum that can be generated depends on the current air pressure (location, altitude above sea level). The output pressure must be at least 1 bar higher than the chosen test pressure.
