OPERATION
WARNING: HIGH
VOLTAGES
ARE
EXTREMELY
DANGEROUS. NEVER MEASURE DC
VOLTAGES
IN
EXCESS
OF
40,000 VOLTS.
This
probe
is
designed
to
permit
high voltage
measurements
to
be
made
as safely as possible. However, ALWAYS MAKE
SURE
THAT
THE
GROUND
CLIP
IS
CONNECTED TO
THE CHASSIS
OF
THE UNIT UNDER TEST AND
THAT
THE SWITCH ON THE PROBE
IS
IN
THE
OFF
POSITION
WHEN YOU ARE NOT MAKING AN
ACTUAL
MEASUREMENT. While
the
conductors
inside
the
handle
and
ground
lead never have
more
than
about
a
tenth
of
a
volt across
them
when
properly
connected,
these
parts will
be
exposed
to
the
full voltage
under
test
if
the
ground
lead
is
not
connected
to
the
chassis.
Whenever possible,
contact
the
high voltage terminal
under
test
with
the
power
turned
off.
Then
turn
the
power
on,
sl
ide
the
probe
switch
to
the
on
position,
take
the
reading,
sl
ide
the
probe
switch
to
the
off
position,
turn
the
power
off,
and
remove
the
probe
from
the
circuit
under
test.
Be
sure
the
slide switch
is
in
the
OFF
position
when
the
Probe
is
not
in use.
IN
CASE
OF
DIFFICUL
TV
Most kits
returned
for repair,
do
not
function
properly
due
to
poor
solder
connections.
Therefore,
many
troubles
can
be
eliminated if you carefully inspect all
the
connections
to
make
sure
they
are
soldered as described
in
the
"Soldering"
section
of
the
"Kit
Builders
Guide."
Reheat
any
doubtful
connections
and be sure all
the
wires are soldered
at
places
where
several wires are
connected.
Recheck
the
wiring.
Trace each lead
in
colored
pencil
on
the
Pictorial as it
is
checked.
It
is
frequently
helpful
to
have a friend
check
your
work.
Someone
who
is
not
familiar
with
the
kit
may
notice
something
you have
consistently
overlooked.
NOTE:
In
an
extreme
case
where
you
are unable
to
resolve a
difficulty, refer
to
the
"Customer
Service"
information
in
the
"Kit
Builders
Guide."
