Jarhead Diagnostics Voltage Drop Diagnostics Parasitic Draw Tester is exactly as the name states. You use this tool with any oscilloscope that allows for custom math channels. With this tool, you’re measuring the voltage drop across the VDD, which when inputted in the scope correctly will show you the amperage of whichever system you’re checking at that time. There are benefits of using this over an amp clamp or multi-meter. Such as no “drift” in your reading like you run the risk of while using an amp clamp during long overnight tests, this will also give you a much more accurate reading than a typical amp clamp. This is an excellent tool to have in your toolbox when you get those dreaded parasitic drains.
This tool is rated for no more than 4A over an extended period of time, with a peak of 8A.
Each VDD will come with what it ohm’s out at, this will allow you to build the custom probe for your scope. If you need assistance with building a custom probe, please feel free to email us and we will gladly assist with this.
Every VDD Box will come with 2 leads and 2 alligator clips.
