    I'm new here and by no means an electrician.
    I was left a fluke 902 by my neighbor who moved out. I just wanted to test it if it works but when checking AA batteries for example it gives me different readings when I reverse polarity. The same battery shows 1.2 and -1.5 when turned around.
    Any ideas? Any recommendations on how should I test if it works properly?

    You just tested if it works properly, evidently it doesn't if it measures a different voltage just by reversing the polarity. I assume you repeated the test?
    Change the internal batteries then try testing a different (new) battery and maybe try a new set of test leads, however you can't check if it's working properly unless you compare it to known good device or use a calibrated voltage or current source.
    It is designed primarily for HVAC work (and by the way you can't check batteries are OK with a voltage check alone).

    Maybe in reverse mode a diode comes into play,
    this would account for the extra voltage drop ?
