The
rules
listed
in
this

2.
USE
EXTREME
CAUTION
when
working
with
high
voltages.
3.
DO
NOT
measure
voltage
if
the
voltage
on
the
"COM"
input
jack
exceeds
1000V
above
earth
ground.
4.
NEVER
connect
the
meter
leads
across
a
voltage
source
while
the
function
switch
is
in
the
current,
resistance,
or
diode
mode.
Doing
so
can
damage
the
meter.
5.
ALWAYS
discharge
filter
capacitors
in
power
supplies
and
disconnect
the
power
when
making
resistance
or
diode
tests.
6.
ALWAYS
turn
off
the
power
and
disconnect
the
test
leads
before
opening
the
covers
to
replace
the
fuse
