Seeking Feedback - How often have you used a Low Resistance Micro-Ohmmeter?

If you have the time, I'd appreciate if you voted in this poll. I'd like to get a sense of your need and use of low resistance micro-ohmmeters. Thanks.

    I can imagine them being extremely handy for measuring electrical contacts, such as relays to examine if they are failing, or for checking the resistance quality of shielding or grounding between different parts of a system or enclosure perhaps!

    I don't have a micro-ohmmeter, but do have a couple of milli-ohmmeters (one commercial one, and one that was a DIY project  Building Frank's Milliohm Meter   that is pretty accurate (and that one has the characteristic that it doesn't pass high current through the device under test [for some applications that's a very useful property, although other applications may not require that]); it can even be used to measure MOSFET on resistance.

    I've wondered if one could be used to monitor the condition of copper AFILS loop tapes. One of the problems I often see is water ingress rapidly corroding them due to the close proximity to concrete. (Another is damage from carpet fitters knives during carpet repairs.) However they are often laid under expensive floor coverings which makes routine inspection difficult and expensive. Being able to monitor the condition routinely would allow for scheduling a repair before it failed completely.

    Interesting use! Maybe the inductance may be an issue, although some meters may be more stable than others. Presumably the industrial meters are more immune to that.

    Also, some meters may use a slow AC measurement I guess, although others use DC (such as Frank's one). That might not be an issue though.
