Connect the red test lead to the "+" terminal and the black to
the "COM" terminal.
Put the touch prods into contact with the circuit to be tested.
If the resistance is less than R < 75 Ω ± 25 Ω, the buzzer will
make a continuous sound.
Note : Always ensure that the circuit is disconnected from the
power supply before measuring continuity! To offset lead
resistance, short circuit the lead touch prods, then press on
