    Hi Wayne,

     

    Thanks for your post. 

     

    1) Yes, we are aware of this issue. It will be fixe on the new App release next week.

    2) There's no better way to do this, if your fuse is not okay you can always get more at shop.pokitmeter.com

    3) The oscilloscope has 2 ways of triggering. If the trigger is in auto then you have to press the red button in the middle to make it trigger. If you want to use the trigger level, then press the "Trigger auto" button and it will change to Rising trigger. If you want to change it to falling trigger, just press the rising trigger word that sits on top of the trigger line.

    4) The input impedance is 1M Ohm for all ranges except for values under 1Volt, which goes is 2M Ohms.

     

    Hope this answers your questions.

    1. Good to hear it will be fixed soon.

    2. I think my spare fuse PCB was a touch too long, so it would not go deep enough to make a good connection.

    3. Yes, I can set the trigger level, but getting it to actually trigger has been a problem. I have a pulse that is around 40us, from about 13V to 14V, that I was wanting to catch. Even using AC coupling, so it is 0V to 1V, doesn't help. I'll keep trying.

    4. I made a X 10 input a couple of weeks back. It appeared to have a much lower than 1M impedance. I don't recall now what I saw. But it is working and giving me the proper results.

    Also:

    A. Is there a limit to the log size? I didn't see anything defined, but it appears to be limited.

    B. The time in the log file appears to be meaningless. I suspect there is no real time clock in the Pokit. I would prefer that there was a header in the log file stating the step time and voltage range. Then the time for each step could be calculate back from that.

     

    Thanks.
