DESCRIPTION
Ideal
for
use
where
measurements
must
not
appreciably
disturb
the circuit
being
tested,
the
Model
Sears 5205
features
high
50,000
ohms/volt
DC and 10,000
ohms/volt
AC
sensitivities,
on
one set of voltage
ranges.
A second group of voltage ranges
with
-
sensitivities
of
25,000
ohms/volt
DC and 5,000
ohms/volt
AC
has
been
designed
into
this instrument.
Because of
the avail-
ability
of
12 DC
voltage
ranges
and
8
AC voltage
ranges, more
accurate
readings
are possible
with
this
instrument
than
with
an
ordinary
VOM.
Also included
are ten DC current
ranges and
five
resistance
ranges
to
assure precise current
and
resistance
indications.
In conjunction
with
a
power
supply,
the
Model
Sears 5205 can be used to measu
re
capacitance
and inductance.
Special
circuitry
has
been
included
to protect
the meter
move-
ment
against accidental
overload.
A
mi
rror
arc has been
pro-
vided
to help eliminate
parallax
errors
from
readings.
A
con-
venient
carrying
handle
built
onto
the
case can also be used to
Position
the meter for easy
reading.
The
Sears 5205 is a quality
product
in both performance
and
appearance.

HOW
TO INSTALL
BATTERIES
Remove the screws
in the rear
cover
of
the
case-
Lift
the
back of
the
case
off
the
front
section.
Note the
orientation
of the bat-
teries
in their
compartments.
When
replacing
the"
AA"cell,
the
positive
(+)
end of the cell should
be at the end so
indicated
on
the case closest to the top.
Be sure that the contact
at
each end
of the compartment
makes a good connection
with
the
metallic
battery
terminal
at
its
positive
end
and
with
the
metallic
portion
of the battery
case at its negative end.
The 9 volt battery
must
be
so
oriented
that its plus terminal
is
at
the connector
marked
"+"
in the case (closest
to
the
side)
and
its minus
terminal
is
at
the connector
marked
"-".
Slide the
battery
straight
down into
its compartment,
being sure that
it is
held
firmly.
