This is a very good concept introduced in power probe 4 tester as it would help the technician in detecting the current and also the tester would automatically set the amps when required.

After a thorough research on both the electronic circuits Power probe 3 and probe 4 one can indicate that power probe 4 is way better than power probe 3 in almost all the parameters like the cable length, display type, circuit breaker etc. Power probe 3 is placed around 12-24VDC which is normal for most of the electronic circuit testers which is considered as good. More is the volt better is the output is my take. Power probe 3 is provided with good volt. At Power Probe, we believe things should be simple. That’s why we design tools to make complex automotive technology accessible for the modern auto technician. As automotive technology continues to evolve, Power Probe will provide innovative Technology, Energy, and Knowledge solutions for technicians and consumers alike.Voltage drop detection is one which detects the drop in the voltage current with the help of an electronic circuit tester which is connected to the vehicle. This is a good function as sometimes it becomes difficult to know if there is a voltage drop. The cable length is the wire which is connected to the vehicle from the electronic circuit to find defects in the vehicle motor and engine parts. Power probe 3 is provided with a single line LCD screen which projects the parameters to recognise how good is the vehicle turning up and if there are any flaws in the engine and other vehicle parts as well.

The voltage rating is the factor which decides how much colt of power is passed to the vehicle via the cable attached to the electronic circuit tester. This factor is important as it is the one which passes the current to the vehicle.Power probe 3 is provided with a one year warranty which is good considering the frequent usage of the product in finding faults within the vehicle engine and other parts.

This can sometimes lead to damages to electrical circuits on which technicians are working on and also becomes dangerous if not attended to. This is where a circuit breaker comes in handy.

Display type is the screen which visualizes the diagnosis of the vehicle one is testing. The display type helps the technician to analyse various parameters and rectify them based on the readings captured.
