As good as any fluke meter I have. Its my all time favorite meter,more so than field piece. Its just my preference I suppose. Review: Great Tester - Have used this unit for many years, think the latest one is number 6. As a electrician and refrigeration technician is fills all the gaps other testers don't. Greatest point is the size of clamp for amperage, you can usually get it snuck in areas others don't on 3/0 and little bigger. Price is great to. I have Fluke meters, but this is preferred tester. ## Features - INDUSTRIALGRADE: The DL389B is a commercial grade clamp meter with enhanced capabilities for every industrial setting.
