I'm trying to check resistance, but my multimeter is acting crazy. I have the dial correctly set to ohms and both prongs attached correctly, but the digital guage is just steadly climbing. When the prongs are not connected to each other I have no reading, as it should be, but whenever the prongs are connected it gives me a reading that is slowly increasing and the craziest thing is that the number increases while the prongs are not connected. i.e. I connect them for a sec and they read 35.6 unconnect them for a min and then reconnect them and it will read 37.8. I have changed the battery and checked all connections, but can't figure out the problem. Can anyone please help!
