tinuity check. If conti-
nuity LED turns “On,”
the fuse is good. If the
continuity LED does
not turn “On,” the fuse
is defective. (61-086
only)
With power on: Place
tester across the “source” side of one
fuse and the load side of an adjoining
fuse. If no voltage is indicated, the fuse
next to the load side prod is blown. If
voltage is indicated, the fuse next to the
load side prod is OK. Repeat the same
test with the prods on the opposite side
of the same two fuses to check the other
fuse.
On a three phase circuit, repeat the
same test as above. An indication of no
voltage or lower than normal line volt-
age indicates the blown fuse.
• Finding Grounded Side of Line
(neutral)
Hold one test prod to the ground and
touch the other test prod to each of the
line terminals until one is found that
does not give a voltage indication. The
continuity LED should be “On.” This is
the grounded side of the line.
