Determine the polarity and circuit circumstance (short/ open).
Activating the components with positive or negative current without jumper wire.
Testing the continuity of the circuit.
Illumination.
Locate missing cylinders.
Measuring frequency of the high-tension ignition pulses and we could calculate the rotational speed of engine according to the measured frequency.
Peak detection.
Testing the voltage of the circuit and the voltage reading will be indicated on the LCD display within 1/10th of a volt.
