6. Remove power from the circuit under test, then open

up the circuit at the point where you wish to measure
current.

7. Connect the black test probe tip to the negative side of

the circuit.

    Connectthe red test probe tip to the  positive side of
    the circuit.
8.   Apply power to the circuit.
9.   Read the current in the display.
