Operation Introduction
Before Test:
1.Before you test a battery in a vehicle, turn off the ignition, all accessories and loads. Close all of the
vehicle's doors and trunk lid.
2.Make sure the battery terminals are clean. Use a wire brush to clean them, if necessary.
NOTE: This tester works best if the battery connectors have been removed and the battery posts have
been cleaned. Any corrosion between the tester clamps and the battery connectors, or between the
battery connectors and the battery posts, will degrade the tester's efficiency.
3.Connect the RED (+) Positive Battery Clamp to the (+) positive battery terminal, and connect the BLACK
(-) Negative Battery Clamp to the (-) negative battery terminal. Ensure that the clamps are securely
attached to the correct terminals.
4.Open the Bluetooth on mobile device or tablet.
