Changing The Battery; Changing Fuses - 3B SCIENTIFIC PHYSICS Escola 100 Manual De Instrucciones

12. Battery and fuses
The battery and the two fuses are located under-
neath the back cover of the meter.
One fuse each is provided for the 3 A and 10 A
sockets:
FF10 A/600 V, breaking capacity: at least 10 kA
(3B order number: 5008564)
The polarity is indicated by plus and minus signs
inside the fuse holder compartment. A mechanical
system ensures the battery makes no contact if it
is inserted the wrong way round.

For cleaning, use a soft cloth, slightly mois-
tened with alcohol, or a brush.
Electrostatic charging of the display window can
affect the measurements under certain circum-
stances:

To remove such charge, use a soft cloth
slightly soaked in alcohol or a paint brush.
Dirt or moisture in the measurement sockets can
affect readings.

Shake out any dirt that may be in the meas-
urement sockets.

Soak a new swab with isopropyl alcohol and
work around the inside of each measurement
socket.

The packaging should be disposed of at local
recycling points.

Should you need to dis-
pose of the equipment
itself, never throw it
away in normal domes-
tic waste. If being used
in private households it
can be disposed of at
the local public waste
disposal authority.

Comply with the applicable regulations for the
disposal of electrical equipment.
