PE-FE connection
In the case of ungrounded (or unearthed) test objects, PE-FE must
be connected to the short-circuit bridge.
In the case of grounded (or earthed) test objects, the short-circuit
bridge must be removed, otherwise double-ground compensation
currents might arise and lead to measurement errors.
