AC CURRENT MEASUREMENT
CAUTION: Do not make current measurements on the 10A scale for
longer than 30 seconds. Exceeding 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:
• 4000µA AC - set the function switch to the µA position and insert the
red test lead banana plug into the µA jack.
• 400mA AC - set the function switch to the mA range and insert the red
test lead banana plug into the mA jack.
• 10A AC - set the function switch to the 10A position and insert the red
test lead banana plug into the 10A jack.
3) Press the mode button until ‘’AC” appears on the display.
4) Remove power from the circuit under test, then open up the circuit at
the point where you wish to measure current.
5) Touch the black test probe tip to the negative side of the circuit.
6) Touch the red test probe tip to the positive side of the circuit.
7) Apply power to the circuit. Read the current in the display. The display
will indicate the proper decimal point, value and symbol.
RESISTANCE MEASUREMENT
WARNING: To avoid electric shock, disconnect power to the unit
under test and discharge all capacitors before taking any resistance
measurements. Remove 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.
3) Insert the red test lead banana plug into the positive VHz% jack.
4) Press the mode button until Ω appears in the display.
5) 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.
6) Read the resistance in the display. The display will indicate the proper
decimal point, value and symbol.
