4. For current measurements up to 10 A, set the rotary
function switch to the 10A position and insert the red
test lead banana plug into the 10A jack.
5. Press the MODE button to select “AC” or “DC” current.
6. Remove power from the circuit under test, then open 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.
9. Read the current measurement on display. The proper
decimal point, value, and symbol will be indicated.
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 rotary function switch to the
Ω
position.
2. Insert the black test lead plug into the negative COM
socket and the red test lead plug into the positive
Ω
jack.
3. Press the MODE button until “
Ω
” appears in the display.
4. 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.
5. Read the resistance measurement on the display. The
display will indicate the proper decimal point, value, and
symbol.
