I've got a cheap multimeter (Velleman DVM890L) and recently I decided to measure the resistance of a microphone I've got to see if it equaled the quoted impedance (I'm trying to learn about all this) anyway, the ohmmeter kept creeping up and up, even with just the two test leads touching. I thought it was a dead battery so I've replaced it, but now it shows 0.63 ohms with the test leads touching - or 1.7 another time I tried it - does anyone know what's going on?
Thanks, and please bear in mind I only have a GCSE level of electronics knowledge...
