## Questions & Answers

**Q: Does this tester have high enough resistance to load a circuit while testing like a traditional incandescent test light?**
A: To load (draw current) one needs a low resistance, not high.  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. Display only lights up
