Hello and welcome to the forum!
Great to see more ag technicians here. A good place to start would be to take a look at the dedicated heavy duty and off highway sections on the forum -
forum483.html.
As a New Holland service tech did you know that you should already have a scope in your dealership? Might be worth asking around to see if you have a DATAR scope. This will be a PicoScope but allows you to use the bespoke DATAR scope software which comes with guided tests made specifically for the machinery you will be working on.
The scope has a place in many environments with construction and agricultural starting to see the benefits it can bring to diagnosis. We will be releasing a number of guided tests with this industry in mind looking at 24V battery testing, Denox 2.2 aftertreatment and J1939 decoding to name a few.
Please reach out if you need any support or advice.
Kind regards
Ben
