Description:

BIG8221 is an equipment used to test automotive electrical system within 12V – 24V. In order to save testing hours for automotive electrical system, BIG8210 is designed to testing the system without re-connection
between vehicle battery and testing components.

Main Functions:

• 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.
• Locating missing cylinders.
• Measuring frequency of high-tension ignition pulses and calculating the rotational speed of engine according to the measured frequency.
• Peak detection.
• Testing the voltage of a circuit and LCD display will indicate the voltage value within 1/10th of a volt .
