Applications:
• Locating Blown
Fuses
With power off: Place
tester across the sus-
pected fuse to perform
continuity check. If
continuity LED turns
"On," the fuse is good. If the continu-
ity 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.
