• For current measurements up to 400mA, set the function switch to the mA
position and insert the red test lead banana plug into the mA jack.
• For current measurements up to 4000µA, set the function switch to the µA
position and insert the red test lead banana plug into the µA jack.
2) Press the MODE button to indicate “AC” on the screen.
3) Remove power from the circuit under test, then open up the circuit at the point
where you wish to measure current.
4) 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.
5) Apply power to the circuit.
6) Read the current displayed on the screen.
RESISTANCE MEASUREMENT
To avoid electric shock, disconnect power to the test area 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
CAP 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 Ω jack.
4) Press the MODE button until “Ω” displays on the screen.
5) Touch the test probe tips across the circuit or part being tested. It is best to
disconnect one side of the part being tested so the rest of the circuit will not
interfere with the resistance reading.
6) Read the resistance displayed on the screen.
CONTINUITY CHECK
To avoid electric shock, never measure continuity on circuits or wires that have
voltage on them.
1) Set the function switch to the Ω
CAP 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 VΩCAP jack.
4) Press the MODE button until displays on the screen.
5) Touch the test probe tips across the circuit or wire you want to check.
6) If the resistance is less than approximately 35Ω, the audible signal will sound.
