    PM129B 31/2 Digital meter display problem

    I have another issue now. When I give my sensor's output to the display, the value was displayed in negative. I changed the polarity of the input terminals and the problem was solved. Is it right to do that? Also, my multimeter displays a stable output. For e.g If its 0.15, it is display 0.15...
