    For some reason ~2.5kΩ refers to low impedance, and seems standard for eliminating measurements caused by Capacitive inductance

    Yes, LoZ means low impedance. That seems to be the standard marking on the selector switch.

    It is not wise to use that mode on a circuit board, because you might be trying to read the voltage across a one meg resistor & the 2.5K ohm would present itself as a short circuit, damaging up stream components.
    By the way that was the voice of prudence, not experience speaking.

    Fluke makes an adapter for meters that do not have built in LoZ

    Here is a link to the SV225 Manual.
    http://assets.fluke.com/manuals/sv225___iseng0000.pdf

    Only costs nearly as much as a meter.

    odd. that pricing strategy must have been a fluke.

    I would not call it capacitive inductance. Capacitive coupling, for sure, and capacitive induction in a pinch, but never capacitive inductance!

    A low-wattage bulb will do the same thing.

    Yes, but not as conveniently.
    Just more economically.

    How about electro-static induction ?
