Hello,
I've got a Discover (I suspect that's just a generic brand) digital multimeter, which I recently used to measure the voltage on an electric malfunction on my kitchen.
Immediately afterwards I noticed that the multimeter voltage reading went crazy. Even if the two terminals are shorted, the reading randomly jumps from minus infinity (indicating that it's outside of the specified range) to infinity and various in-between values. This happens whether the multimeter is set to measure DC voltage, AC voltage, or even current.
I had thought that the ohmmeter was working, but it isn't - it consistently measures infinite resistance even if the terminals are shorted.
What might be wrong with my multimeter? Is there any hope, or should I just throw it away and buy a new one?
Thank you for your help.
