AC SUPPLY AND POWER SWITCH
When the R&S SMJ is connected to the AC supply, it automatically sets itself to the
correct range for the applied voltage (range: see type label). There is no need to set
the voltage manually or change fuses.
The instrument comes with or without a power switch, depending on the design of the
otherwise technically equivalent power supply unit.
The power switch can be set to two positions:
●
0
The instrument is disconnected from the mains.
●
I
The instrument is power-supplied. It is either ready for operation (STANDBY) or in
operating mode, depending on the position of the ON/STANDBY switch on the
instrument front.
