Safe operating conditions
1)
Do
not
measure voltage in excess
of
lOOOV
peak.
2)
Observe the maximum input as stated in the specification.
3)
Disconnect the test lead from
the
test points before changing
the
me
ter function and range.
4)
Be
careful not
to
touch the terminals or probe tip
when
measuring
above 60VDC or
2SVAC.
5)
Never
attempt a
voltage
measurement with a test lead in
the''A''
or
rnA
input terminal.
6)
Do not measure more
than
lOA(which will display
"OL")
and
do
not
continue
measuring
high
current
above
IDA
for more than 3
minute.
To
avoid
opening
fuse
and
overheating circuits. The suc-
cessive measurement
shou
ld
be
done
after more than
10
minutes
for
cooling
down.
7)
Do
not attempt a current measurement
when
the voltage
is
above
600V
8) Remove the test l
eads
before
opening
the case to avoid electrical
shock.
9) Disconnect the live test lead before disconnecting the
