switch
to desired
"CAP"
position.
2. Before
measurement,
all capacitance
ranges should
be
set
to zero,
with an open condition
without
a
condenser
connected
to
CAP sockets, rurn
the
"CAP
ZERO ADJ"
so that zero reads
on display.
3. Connect capacitance
test leads
to condesser (For
mea-
surement
of polarized
qondensers,
have
the
polarities
of
the
CAP sockets,
agree with those
of a condenser).

1. This
instrument
is provided
with a 2Al250V
fuse to
protect
the
current measuring
circuits
which measure
up
to 2000mA.
t
To
replace
the fuse, slide the battery cover upward by
pressing it inward.
Replace blown
fuse
with
new
2Al250V
fuse. To
prevent
fire, do
not
use a
fuse
which
has
a
higher rated value
than
soecified.
Calibration
We
do
not recommend that
yorl
attempt
calibration
yourself. It
is a
highly technicai procedure that
requires
an
extremely accurate
power supply. If
your
knowledge is
complete and
you
have such
a
power supply,
fol1ow these
instructions.
1. GENERAL
1-1.
Perform
calibration
at
an
ambient temperature of
74oF to
80oF
and a relative
humidity
of 80% or
less.
Allow instrument
to stabilize
at
this
temperature
for
at least 30 minutes.
