I have not come across this issue before in searches on this forum and searches on Google. I wonder if anyone else has come across it.
My digital multimeter is unable to measure ohms. I'm just trying to read a simple single 100R resistor but the readings fluctuate.
I took the leads out and replaced, but still have the same problem.
I took out the leads completely, and the multimeter still shows a reading even when open circuit.
Can this be fixed or do I have to buy another one?

Thanks in advance for your guidance.

Low or dead battery is the common cause. The internal voltage reference is not very stabile when the battery gets below a certain level (exact value depends on the exact meter used). In any case, battery is the issue about 90% of the time. Other issues can be broken test leads or poor connections in the banana jacks in the meter.
Good luck
