Setting the Supply Voltage
Possible damage to the instrument from incorrect AC supply voltage
An incorrect AC supply voltage setting can lead to damages to the instrument when the
instrument is connected to the AC supply.
For this reason, check whether the correct AC supply voltage is set before switching on
the instrument for the first time.
The AC supply voltage can be changed as follows:
1. Disconnect the power cable.
2. Open the flap covering the voltage selector using a small screwdriver (or similar).
3. Remove the cylinder labeled with the nominal voltages and reinsert it so that the
value visible through the hole in the cover flap when refitted corresponds to the
desired nominal voltage. If the desired voltage is not printed on the cylinder, select
the nearest suitable value according to the table above.
4. Close the flap.
The R&S audio analyzer UPV is operated with the same AC fuses for all specified
rated AC supply voltages. The precise designation of the fuses is indicated on the rear
of the instrument.
2.3.3.2
Switching on the Instrument
1. Connect the audio analyzer to the AC supply by means of the supplied power
cable.
The R&S UPV is in compliance with safety class EN61010-1, it should only be con-
nected to a socket with grounding contact.
