Line-Power Fuse
The
Meter
has a line-power fuse
in
series with the
power
supply. Table 1 indicates the
proper fuse for each
of
the four line-voltage selections. The line-power fuse
is
accessed
through the
rear
panel.
I. Unplug the
power
cord.
2.
Insert a small screwdriver blade into the narrow recess to the left
of
the fuse
holder and pry it to the right until the holder
pops
out. See
Figure
2.
3. Remove the fuse and replace
it
with a fuse
of
an
appropriate rating for the
selected line-power voltage. See Table I.
4. Replace the selector block back into the fuse holder.

Warning
To avoid electric shock or fire, do not use makeshift fuses or
short-circuit the fuse holder.
