Concepts
'LVDVVHPEO\ Disassembly refers to the removal of cover, chassis and other parts in order
to access and replace parts in the M3046A Monitor and the M3015A
Measurement Server Extension. Disassembly does not refer to a complete
breakdown of the entire Instrument since the M3000A Measurement Server
and the M3016A Measurement Server Extension cannot be disassembled.
+LJK9ROWDJH This concept refers to voltages dangerous to life. High voltages can be found
in the Instrument when it is connected to the mains Power Supply and in the
capacitors on the Power Supply board even when the Instrument is not
connected to the mains Power Supply.
