    I don’t use my Mooshimeter every day, or even every month, but I have found it very useful over the years since I bought it (2019).
    Recently I have noticed that the zero for resistance measurement has risen to about 35ohms, which is a minor nuisance, it’s easy enough to zero. Except that the value of this is temperature dependent. Putting the device into an incubator set at 35C and logging internal temperature and resistance which a bridge across the terminals showed and 8ohm drift as the temperature rose from about 24 to 35.
    Something is clearly wrong!
    I have reloaded the firmware, and checked that the app is up to date. I don’t know what else to do — please can you help me?

    I’ve also put in new batteries, even though the last lot were fine…
