Safety pre-tests
Before performing a measurement, the instrument performs a series of pre-tests to
ensure safety and to prevent any damage. These safety pre-tests check for:
Ì
any external voltage against earth on test socket,
Ì
excessively high leakage current,
Ì
excessively high touch leakage current,
Ì
short circuit or too low resistance between L and N on appliance,
Ì
correctly applied mains voltage to the test socket.
If pre-tests fail, an appropriate warning message will be displayed.
The warnings and measures that have to be taken are described in chapter
