DANGER
Potentially lethal shock hazard!
It is essential to switch the unit off and to wait at least one more 1 minute
before beginning the check!
A high resistance measuring voltage source at line frequency and a
measuring circuit compliant with the requirements of IEC 60601 are
required. Complete test units, e.g. the "Bender tester", fulfill these
requirements.
