Use Fluke 18B+ multimeter to check and test most electronic products. The digital meter is easy to use and is significantly improved compared with the original Fluke 18B. Fluke Digital Multimeters (DMM’s) are on more tool belts, finding more problems than any other comparable test tool. Using a Fluke electrical multimeter with the Fluke Connect® app, you can put tools, not your body, near live electrical panels. It’s simple. You can display the professional meter measurement, plus readings from up to 3 wireless modules while reducing the risk of arc flash by separating yourself from hazardous measurement situations.
