The demo-multimeter has a compartment which
houses both the battery and fuses and which is
accessible at the rear once its cover is opened.
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 mechani-
cal system ensures the battery makes no contact
if it is inserted the wrong way round.
