In this case I do not think the manufactures specifies the testers input resistance. It is an important factor for sure. **Q: We purchased ours on 3/10 and it has already stopped working. Is there any guarantee or offered replacement? Barely had a month...** A: dose not work how to replace **Q: Is it suppose tp have a fuse in it?** A: No fuse needed, the electronics in it work on the power when its connected to the power of whatever ur working on. **Q: Does it bave light and beeper?** A: No beep.
