Hey Brin, thanks for all the great videos. Hope your all doing ok in these crazy times? Your videos help me get away from the chaos and learn more and more each day. Question- I want to by a Pico scope kit, I see they have the new 4425A out. Do you think I’ll be ok with the 4425 original? I know there also changing the software. What are you thoughts? Hope I get to meet you at the TST event!❤️❤️
So in your opinion would you suggest using an attenuator every time you test a fuel injector or an ignition coil? I'm a recent owner of a new picoscope 4425. Thanks for the great videos they are very helpful.
It's always the safest approach to use an attenuator when testing these circuits. The 4425 does have a higher voltage input maximum than the elder 4423 but there is still always the risk of powerful inductive kicks. I am not aware of any downfall of using an attenuator ( other than a few additional seconds of hookup and setup).
Would you recommend getting the 2204A or 2205A or 2405A for automorive diagnostics for a DIY dude such as myself? Would you recommend getting a USB oscilloscope to go with OBD2 scanner?
Look at the maximum input voltages of the inputs on your tool. If the voltages your measuring is more than the inputs can handle, the input needs attenuation.
A pierce probe was carefully used. Most of us encourage the use of a pierce probe due to us experiencing scenarios when a backprobe FIXED a poor connection at a connector. You also risk shorting adjacent circuits as a backprobe pin enters the connector. As long as the technician probes the wire gently as to not damage the conductor AND properly seals the insulation when testing is complete, there is absolutely nothing wrong with using a pierce probe. I personally encourage the use of "Phils probe" from AESwave for many reasons but one being that the probes portion of the insulation will have tiny, almost microscopic holes instead of a big needle hole from some less quality pierce probes. Regardless of which tool you use, always practice professionalism! Make sure your connections are safe, least intrusive and properly insulated when repairs are complete!
@@TrainedbyTechs alright, some want's the Daugther other the Mother 😁😁 I prefere the back-probe all the plugs today have channel for the wire connection, so I think the chance for short wire ain't so big 😵
