6. Remove power from the circuit under test, then open up the circuit at the point where you wish to
measure current.
7. Touch the black test probe tip to the negative side of the circuit. Touch the red test probe tip to the
positive side of the circuit.
8. Apply power to the circuit.
9. Read the current in the display. The display will indicate the proper decimal point, value and symbol.
AC CURRENT MEASUREMENTS
WARNING
T
O AVOID ELECTRIC SHOCK
,
DO NOT MEASURE
AC
CURRENT ON ANY CIRCUIT WHOSE VOLTAGE EXCEEDS
250V AC.
CAUTION
D
O NOT MAKE CURRENT MEASUREMENTS ON THE
10A
SCALE FOR LONGER THAN
30
SECONDS
. E
XCEEDING
30
SECONDS MAY CAUSE DAMAGE TO THE METER AND
/
OR THE TEST LEADS
.
1. Insert the black test lead banana plug into the negative (COM) jack.
2. For current measurements up to 4000
µ
A AC, set the function switch to the
µ
A position and insert the
red test lead banana plug into the (
µ
A) jack.
3. For current measurements up to 400mA AC, set the function switch to the mA range and insert the red
test lead banana plug into the (mA) jack.
4. For current measurements up to 10A AC, set the function switch to the A position and insert the red
test lead banana plug into the 10A jack.
5. Press the AC/DC button until “AC” appears in the display.
6. Remove power from the circuit under test, then open up the circuit at the point where you wish to
measure current.
7. Touch the black test probe tip to the negative side of the circuit. And touch the red test probe tip to the
positive side of the circuit.
8. Apply power to the circuit.Read the current in the display. The display will indicate the proper decimal
point, value and symbol.
RESISTANCE MEASUREMENTS
WARNING
T
O AVOID ELECTRIC SHOCK
,
DISCONNECT POWER TO THE UNIT UNDER TEST AND DISCHARGE ALL CAPACITORS
BEFORE TAKING ANY RESISTANCE MEASUREMENTS
. R
EMOVE THE BATTERIES AND UNPLUG THE LINE CORDS
.
1. Set the function switch to the
Ω
position.
2. Insert the black test lead banana plug into the negative (COM) jack and the red test lead banana plug
into the positive
Ω
jack.
3. Touch the test probe tips across the circuit or part under test. It is best to disconnect one side of the
part under test so the rest of the circuit will not interfere with the resistance reading.
4. Read the resistance in the display. The display will indicate the proper decimal point, value and symbol.
