    For the test no high vacuum is needed. As a rule, an absolute test pressure of about 10 – 20 mbar is fully sufficient. Upon start of operation, the leakage test system carries out a preliminary leakage test and only in case of a positive result, the SF 6-gas is filled in resp. the final precision test started. Pressure and vacuum are permanently monitored during the process.
