HOW TO CPEN THE CASE
Removal of the four screws in the back of
the case (with а 1/Д" screwdriver) provides easy
access to the complete interior for adjustment
or replacement of parts. Lifting the front panel
straight forward out of the case brings meter,
batteries and printed circuit out as a unit.
BATTERY REFLACEMENT
Five batteries supply power for resistance
measurements - one large (Size D) flashlight cell
and four smaller (Size AA) penlight cells.
When it is no longer possible to bring the
pointer to zero ohms (see ZERO OHMS ADJUST, p.22)
on the R x 1 апа R x 100 ranges, replace the large
cell. If this occurs on the R x 10,000 range, |
replace the four small cells.
OBSERVE POLARITY
All cells are held in place with specially
designed spring battery contacts, whose polarity
is either marked or plainly evident. Be sure that
replacement cells are inserted correctly.
FUSE REPLACEMENT
Remove the front panel and extract the burned-
out fuse from the fuse clips located below the
range switch. Replace only with a 1 amp. 250 1,
fuse, type 3AG (1-1/A" x 1/4") or equal.
If your multimeter was produced prior to
August 1961, it is equipped with an electrically
identical pigtail fuse with soldered connections.
To allow the use of а clip-in fuse, a fuse
block conversion kit including fuse and install-
ation instructions is available at nominal cost.
