    There is a lot of residential work thats not just 0V or 110/120V. If you are doing any work on your HVAC system you will see 24V, 0-10V analog signals. And you can’t just turn the furnace or AC off if you want to troubleshoot some electrical issues.

        I’m going to warn anyone reading this thread away from the ones sold by harbor freight. They work okay at first, but they suck for forgetting to power them off. My last one is registering voltage at about 40%.

        Professionally, a cheap digital multimeter will be fine in most aspects. I would say $15-20 Is fine. If you are doing deep circuit troubleshooting then you might want to consider something like a fluke.
