    Hey just some advice..... I purchased a DIGITECH QM-1462 from
    JAYCAR... for the datalogging via USB. I currently have a
    inttermittant current draw on a vehicle.. This meter is only capable
    of doing a 4000 count, which only is about 1.5hrs MAX only problem is
    that it AUTO POWERS OFF before it even gets to maximum count. I was
    wondering is there a meter out there that will datalog via pc over a
    long period????? or is there a way to turn the "Auto power off"
    feature off??????? anyhelp would be great




    Thanks

    get something that works, and ask for your money back from digitech

    Don't know if this will help, but my EXTECH LCR meter allows you to turn the
    Auto Power Off feature off by continuing to hold the button down when
    powering it on. Instead of just hitting the button, you hold it down for a
    second or two, and the meter beeps a second time, and shows APO OFF on the
    LCD display. Maybe meter will do something similar? Don't know, but it's a
    thought...

    Good luck,

    Dave

    I guess you bought this new meter in the belief it would do what you wanted. I
    see no data available on Jaycar's site so I presume you must just have hoped it
    worked that way. Certainly I see no online data sheet or operator's manual.

    If it doesn't do what you need, I suggest you explain that to Jaycar and send it
    back for credit. It seems pretty dumb to design something suitable for
    datalogging that switches itself off !

  5. There usually is on most meters, like holding a button on power-up to
    switch it off.
    Have you read the manual?
    Some meters have the power-up options written on the bottom of the
    case.

    It may seem strange but i default to handheld for utility DMM. The
    recommendation if you are talking about small bench meters could be
    very different. My current handheld is a Tek DMM 155. I do not
    currently have a bench top, but if i were looking i would surely
    check Keithley.
