General Information; Changing The Fuse - 3B SCIENTIFIC PHYSICS 1003315 Manual De Instrucciones

2. Description
The transformer with rectifier provides small
voltages, switchable in four voltage steps, with
outputs in the form of AC voltages or full-wave
rectified DC voltages.
The maximum load for each output is 3 A. Both
outputs are protected against short-circuiting.
The 1003315 transformer is for operation with a
mains voltage of 115 V (±10%), and the
1003316 unit is for operation with a mains volt-
age of 230 V (±10%).

4. Operation

4.1 General information


The AC and DC outputs cannot be used at
the same time

Before connecting the plug to the power
supply, set the voltage selector switch to
zero.
4.2 Obtaining an AC voltage

Connect the load to the AC output sockets
(1).

Set the voltage selector switch (3) to give the
required voltage; if necessary connect a
voltmeter in parallel with the load.

Connect the unit to the mains supply.

It is not permissible to
cascade multiple de-
vices and short them
out. This causes overlo-
ading of the polyswitch.

(2).

Set the voltage selector switch (3) to give the
required voltage; if necessary connect a
voltmeter in parallel with the load.

Connect the unit to the mains supply.

4.4 Changing the fuse


Unplug the mains plug.

Unscrew the fuse holder on the rear side of
the housing with a screwdriver.

Replace the fuse and reinsert the holder in its
socket.
5. Care and maintenance

Before cleaning the equipment, disconnect it
from its power supply.

Use a soft, damp cloth to clean it.
6. Disposal

The packaging should
be disposed of at local
recycling points.

Should you need to
dispose of the equip-
ment itself, never throw
it away in normal do-
mestic waste.
regulations for the dis-
posal of electrical
equipment will apply.
