## Questions & Answers

**Q: What fuse and where can I buy a replacement mA fuse?**
A: 20A & 800mA. Try Amazon, e.g., Zephyr Fast Acting Glass Cartridge Fuse 6pk $7.49 for the 20A.

**Q: Does this come w/english manual?  uni-t looking at comew only w/chinese manual. manual is useful for some quirky features of each meter.**
A: YES,with English manual. Also welcome to email BT@BESTMETER.CN to get the PDF version manual

**Q: Does the continuity check make a beeping noise of any sort?**
A: Yes, Beeping noise with light flashing, so if even you can't hear the "BEEP" in noisy environment, you can still judge the wire from the flashing light.

**Q: I popped the 20 amp fuse. Does anyone know the replacement fuse part number or a push button breaker that could be wired in its place?**
A: You can get that fuse at any Radio Shack. The fuse size is listed in your manual.
