Grounding
The Portable BLACKBOX contains two independent ground systems, one for measurements &
one for safety. Internally the ground systems are isolated in order to avoid ground loops.
Externally they may be safely connected to the same or different ground systems.
 Point 1 - Measurement Ground: The reference point for measured electrical
system,
 Point 2 - Safety Ground: The reference for the line cord ground. Enclosure for
connectors related metal parts:
NOTE NOTE NOTE
 Maximum permitted voltage between Measurement & Safety Grounds is 2kV DC or
1.5kV AC.
 The Ground input is the reference for all channels therefore it is essential to
connect it properly.
 Proceed to the next step - Plug and Play Voltage & Current Probes
