Safety precautions and warnings prevention personal injury or damage to vehicles and /or the scan tool,read this manual first care fully and observe the the following safety precautions at a minimum whenever working on a vehicle.

1. Always perform automotive testing in a safe environment.

2. Do not attempt to operate or observe the tool while driving a vehicle operating or observing tool will cause driver distraction and could cause a fatal accident.

3. Keep clothing, hair, hands, tools test equipment etc away from all moving or hot engine parts.

4. Operate the vehicle in a well-ventilated work area, exhaust gases are poisonous.

5. Put blocks in front of the drive wheels and never leave the vehicle unattended while running tests.

6. Use extreme caution when working around the incognito coil distributor, cap ignition wires and spark plugs these components create hazardous voltages when the engine is running.

7. Put the transmission in p(for A/T)or N(M/T)and make sure the parking brake is engaged.

8. Don't connect or disconnect any test equipment while the ignition is ON or the engine is running.

9. Keep the tool dry, clean free from oil/water or grease.use a mild detergent on a clean cloth to clean the outside of the scan tool when necessary.

Description

JDiag P100 New Generation Automotive Electrical Circuit System Tester for Cars and Trucks 0V - 70V

General description tool is the best electrical tester, reducing diagnostic time in all 6-30V at vehicle electrical systems after a simple hook-up of the tool to the vehicles's battery, you can

1. Determine at a glance if a circuit is positive, negative or open without having to reconnect clips from one battery pole to another.

2. Test for continuity with its built -in auxiliary ground lead.

3. By depressing the own switch of tester electric, conduct a positive or negative battery current to the probe tip for testing the function of an electrical component without the use of jumper wires.

4. Test for poor ground contacts of this circuit tracer instantly without performing voltage drop tests, the tool is also short-circuit protected its internal circuit break will trip if it becomes over loaded.
