【What is a PB100 Probe Tester?】With the PB100 probe tester, you can check voltage and ground signals in a typical DC circuit. However, the kicker is that you can also use it to send voltage and ground signals. It works like a test light that can power circuits or provide a good known ground. This way, you can effectively test components and circuits without having to break out the old alligator clips and jumper wires. You can power or ground a circuit directly through the top of the device.
【What does it do?】The PB100 is an essential tool for automobile user. It is needed for testing components on and off the vehicle, checking for the good and bad grounds, testing for continuity and diagnosing circuit failures. For example, you can use it to turn on a blower motor. You can run power window motors, windshield wipers, and even rear window defrosters. If the vehicle owner keeps it in his car he can check system failure on his own way no need to go to technician.
