  • How to know when to change battery in multimeter

    From AK@21:1/5 to All on Fri Dec 9 13:30:07 2022
    On my multimeter, the voltage readings get inaccurate over time due to battery discharge. My meters all use 9 volt batteries.

    How can I tell when to change out the batteries?

    Thanks.

    Sounds like time to change the multimeter instead!

    Have you tried one of the lithium rechageable PP3 / 6F22 , they have
    inbuilt BMS which switches out the battery for protection when it gets
    to about 6V. The EBL ones do this. C+
