of these resistances are
also
used
for the Milliampere circuit, we have
tried to
l,rrrllr;l
them
as
much
as
possible,
i.e. for
voltages higher than 140 Volts, by fitting
a fuse
,rr
..crics
with the range
comm0n to the 0hmmeter.
lf
the
0hmmeter does not work cor-
rr,r lly,
the
first thing to do is
check that the fuse has not blown.
llr"
lilse-link may be
checked for continuity using another
chm-meter, or
examined visually,

magnifying-glass.
lf
the
fuse has failed, it shculd be replaced
with one of the
spares

on
the
