If you want to make precise re-
sistance measurements, then
subtract the test lead resistance
found in Step 4 above from the
display reading in Step 7. It is a
good idea to do this for resis-
tance measurements less than
10Ω.
Measuring DC Current
This multimeter can be used to mea-
sure DC current in the range from 0 to
10A. Unlike voltage and resistance
measurements where the multimeter
is connected across the component
you are testing, current measure-
ments must be made with the multim-
eter in series with the component.
Isolating current drains and short cir-
cuits are some DC Current applica-
tions.

To measure DC Current (see Figs.
10 & 11):
1. Insert BLACK test lead into
COM test lead jack.
2. Insert RED test lead into "10A"
test lead jack or "mA" test lead
jack.
3. Disconnect or electrically
open circuit where you want
to measure current.
This is done by:
• Disconnecting wiring harness.
• Disconnecting wire from
screw-on type terminal.
• Unsolder lead from component
if working on printed circuit
board
s.
• Cut wire if there is no other
possible way to open the electri-
cal circuit.
6. Turn multimeter rotary switch
to desired OHM range.
If the approximate resistance is
unknown, start at the largest OHM
range and decrease to the ap-
propriate range as required. (See
Setting the Range on page 8.)
to be connected across the com-
ponent.
If display reading was greater
than 1.5Ω, check both ends of
test leads for bad connections.
If bad connections are found,
replace test leads.
5. Connect RED and BLACK test
leads across component
where you want to measure
resistance.
When making resistance mea-
surements, polarity is not im-
portant. The test leads just have
