500 MILLIAMPERES TO 10 AMPERES
Connect the black test lead in the -10 A.
jack and the red test lead in the +10 A. jack.
Set the range selector switch at 10 AMPS
(common with 10 MA.).
Open the circuit which is to be measured.
Connect the meter in series with the circuit.
Connect the red test lead toward the positive
side and the black test lead toward the neg-
ative side.
Turn on the power in the circuit which is to
be measured. Observe the meter. If the
pointer is deflected to the left, the current
polarity is opposite to that which was antic-
ipated. Turn off the power, reverse the test.
lead connections (the function switch has no
effect on polarity for the 10 AMP range), and
turn on the power again.
Read the current directly on the black D.C.
arce Use the O-10 figures. The current
values are in amperes.
Turn off the circuit power. Remove the test
leads and restore circuit continuity.
