    I'm pretty excited to get this unit. I'm also pretty stoked it has the trigger where you can freeze the screen.
    A number of years back, we did an electrical load analysis on an aircraft to see whether the current generators were strong enough for all of the equipment onboard. After several engine runs, we determined the generators were strong enough.
    However, when you would turn on one piece of equipment in particular, the displays would flicker off for a few seconds seconds and come back on. It was too fast for multimeters which showed 28VDC the entire time. The avionics shop happened to have an oscilloscope that we plugged in an extension cord to the building, and repeated the test. That trigger saved the day, and we observed when we turned on that piece of equipment, aircraft bus voltage dropped from 28VDC to 0 Volts for three... Yes three milliseconds. That was enough to mess with some of the displays.
    We'd never have been able to see it without that trigger function. So to have it in a little handheld $30ish dollar oscilloscope is amazing.

      Trigger is essential to understanding how to get the most out of your scope. Unfortunately…on the DSO 152 you can not adjust the trigger with respect to X axis, meaning the waveform triggers at the extreme left hand of the screen. (In normal, sometimes better to Auto, let it scroll and capture manually (Stop)). Very annoying. Thx for watching 🍻

    Brilliant! Thank you! Probably the best, most clear and informative series on TH-cam I have ever seen and I watch a lot of videos! 😅
    Just a note: Using your examples on screen, I get the same peak to peak voltage, but a Vmax of 1.8 and a Vmin of -1.8, do you have any idea why that would be? Cheers Harley

    • @TheGibby3340
      @TheGibby3340  4 หลายเดือนก่อน +1

      Thx again. Little difficult to say without actually seeing it, but is it possible you had the coupling selected on “AC”?

    • @rnb250
      @rnb250 4 หลายเดือนก่อน

      @@TheGibby3340 thank you for your reply, a calibration seemed to have cleared it up so hopefully this solution, like your videos, may be of help to someone else.
      However, as others have noted elsewhere the unit gives an error when reading voltages below 1v. eg. I measure a 12v battery which measures 12.7v when the units are 1v or higher, but under 1v the voltage shows less than 12v (9v, 6v etc) in the numerical data at the top.
      Another You Tuber made a video about this but I’m not sure if I can post links.
      My personal opinion regarding this is that the unit only calculates the data from what is displayed on screen and if the measurements are beyond the limits of the screen the data becomes incorrect.
      I will try and post the video in another comment here for everyone’s reference.

    Excellent set of videos, great help as I am looking at a Hantek 1008C 8CH USB 2.0 Automotive or Pico 2204A. But don't know which one is the better for automotive as a lot of people say the Pico has the better software. Thanks for taking the time to share. Cheers

    • @TheGibby3340
      @TheGibby3340  8 หลายเดือนก่อน

      Although 8 channels sounds very appealing, the reality is that the 1008 is painfully slow. It is a very rare occasion that more than 2 channels are put to use. But the Hantek is cheap and simple to use, you are likely to “outgrow” it very quickly. Pico make a great product. I made the mistake of selling my 2204A some time ago. Software and hardware are far superior. Speed & image capture capabilities are well worth the slightly steeper cost and learning curve. Thx for watching 🍻

    Can I use a Hanteck or Pico amp clamp with the FNIRSI-DSO 152

    • @TheGibby3340
      @TheGibby3340  4 วันที่ผ่านมา

      Yes. Assuming your current clamp has a BNC connector, your will require a standard BNC to MCX (mini BNC) adapter. Like the link below. Thx for watching. 👍🍻

    Can this scope use a current clamp? Measure injector voltage ? Great video by the way. Like the way you simplify things.

    • @TheGibby3340
      @TheGibby3340  9 หลายเดือนก่อน

      Yes it can. This scope is equipped with a mini BNC connector. So an adapter (BNC female to MCX male) is required. Think I paid $4 for one. Equipped with a X10 attenuator it will be fine for injectors. (again the previously mentioned adapter will be required). Thx for watching 🍻

    • @TheGibby3340
      @TheGibby3340  10 หลายเดือนก่อน

      @bekomcar554 If you are new to scopes, the model in these videos (Fnirsi DSO 152) is a great starting point. Appreciate that it is only single channel, and you will “grow” out of this very quickly. But with a price tag equivalent to half dozen cans of beer….So what. Automotive tech’s at a professional level, typically use a multi channel scope. 2 channels minimum preferably 4. Multiple channels are useful for correlation purposes (cam/crank position for example). PicoScope and Snap On both manufacturer great products. Problem being, purchase prices are very high indeed. The best scope I have is a Snap On Modis scope/scan-tool. Outrageously priced when new. I purchased it used for $450 Canadian dollars. There are many options available, from many manufacturers. Define your needs and research your options. Prices vary widely. Good luck. 🍻
