    I have the same model, almost ten years now. Thanks for sharing the procedure. I will use your video as refference. Thank you and have a good day to you.

    Very helpful, thanks for that, I will have to dig out my one and check it's calibration, I picked it up cheap about a year ago, and haven't used it yet!

      I still need to read the manual yet lol. I need to work out how the triggering is supposed to work on these. They are a pain in that you have to move the measurement cursors around all the time, but handy for smaller jobs.

    I used to have this scope; unfortunately, the screen went black, and there was no replacement available (apparently those 64x128 monochrome graphic LCDs have long since gone obsolete). The biggest problem I had with it is that it used to drain batteries, even when switched off! I ended up operating it off a 9 volt adapter instead.

      Yeah, when not in use I leave one battery out! Or it does go flat super quick (and then the batteries leak...)

    I've always wondered how companies like Fluke do calibrations. The calibrating machine itself has to be calibrated as well I should think...

    • @GadgetUK164

      Absolutely! They have voltage and signal generators that have very very low tolerance and provide extremely accurate outputs - that's what they calibrate against at the factory But I trust the Fluke, it's pretty damn accurate for something like this.

    interesting stuff. Regarding the PSU, have you tried adjusting P1 inside it ?

    • @GadgetUK164
      @GadgetUK164  7 років тому

      To get 0 volts you mean? No, but I suspect using P1 or the other trimmers I might be able to get it to output 0v. The main problem I had in this video is the fine adjust just isn't fine enough when you want to try and get a low mv setting. It was impossible to get 170mV set without using that pot as a divider.

      I watched that part of the video again. I didn't listen properly the first time. Yeah, the fine adjust isn't fine enough kind of saying. :) Maybe an upgrade, more turns multiturn pot ? :)

    is this unit still worth buying or are the cheap ones on Amazon as good?

    • @GadgetUK164
      @GadgetUK164  2 роки тому

      No, there are WAY better ones these days! Any of the super cheap ones beat this - hands down!
