  • In this video, I did a detailed teardown of the OWON HDS272S 3-in-1 handheld oscilloscope/digital multimeter/arbitrary waveform generator and compared to the teardown I did with the Hantek 2D72. High-res teardown pictures can be found at www.kerrywong.com/2021/09/18/t...

    Actually, quite impressive for this unit. First I thought they were handling everything on the ARM and was wondering how the heck it could be so fast, but that FPGA/or PL is quite powerful to have that many LUTs in it.. wow.. thanks Kerry

    I usually laugh those handheld scopes off as toys. It's nice to see a Chinese manufacturer making a good one that is not priced like a Fluke.

    I wanted to make the purchase. But had a doubt about the internals of the HDS272S. To be honest, I didn't except for the internals of a handheld oscilloscope at this price to be this good.
    Thanks for the awesome and detailed teardown video. Huge like from me..

    Thank you for teardown.
    My unit bought at the very same source on 4th of September has been arrived yesterday.
    It has the very same board inside and very same software version like yours.
    So far I like it anyway.

    I would suspect that the current draw varies with the back light intensity, is that function adjustable? Also can the unit be powered from the charger, so it can be used while charging, when the batteries are discharged ?

  • @Zack-fu8sn
    @Zack-fu8sn Год назад +2

    Hello, can you use the multimeter leads to input and see the sinewave from an electrical socket? I've been searching everywhere for this answer as i'm new to oscilloscopes.

    • @hansmoser162
      @hansmoser162 Год назад +1

      No, the DMM section is completely separated from Oscilloscope section and can only measure voltage counts. You can just use the probe (in position 10x !) on the ac socket. But be aware, there are several rules to check before, as mentioned in the manual. So for example don't connect any other devices as USB charger or computers because they will have an own ground connection. Use fully isolated probes with proper voltage declaration. AC outlet measurement is very dangerous and not a job for oscilloscope noobs in my opinion.

  • @hansmoser162
    @hansmoser162 Год назад +1

    Thank you for your detailed teardown. I own the HDS242 and my unit shows a significant DC offset of 1,5V at the 5V range. This offset is drifting temperature related. When calibrated in properly warm status, everything is fine. But I can't always wait 15min to run it completely cold to warm before measurement.
    Is there any component to be better cooled, to get rid off this DC offset drift? For example the 8pin multi OP amp lower right under the display?
    Thanks in advance.

    Have you measured the operating temperatures of the main chips of this device? Are they overheating as it happens on stationary oscilloscopes?

    Hello'. Thanks for the video. I have a question and it maybe stupid, why when you measured current consumption at the video beginning you used only one battery?

    • @KerryWongBlog
      @KerryWongBlog  2 года назад +1

      The two batteries operates in parallel and it's far easier to measure one current path than using two meters and add the results together.

  • @LuK358

    Unfortunately my HDS272 consumes more than 3mA when not active. Far away from some µA you tested. When I dont use the scope for weeks, accus are empty. I refuse to drill a hole for switch :) I don't know whether I would buy it again. The Firmware is 1.5.0, it seems that there is no update available.

      @@daviddirac5942 Well, it would be hard to do the diagnostics over comments, but it sounds like the problem goes beyond just the LCD connection as the DMM inputs and Osc inputs are separate and independent when neither works I'd assume something more serious is going on. Do you remember what was the measurements you did prior to this happening?

    Where are those 2 fuses? I see the big one, guessing its the 10A, but where is the one for 200mA. I also checked manual, but the is not a single word about how to changed a fuse.

    • @KerryWongBlog

      The fuse for the lower current range is a polyfuse, if you take a look at my teardown pictures you will see it's right next to the mA socket.
