I tried out the CL900 on several different projects, ranging from simple electrical measurements to more complex ones involving data capture and analysis. Each time I was able to get accurate readings quickly even in less than ideal conditions where ambient light was low or there were other variables that could have compromised accuracy.
Overall I found the Klein Tools CL900 Digital Clamp Meter to be an excellent tool that is both reliable and precise when it comes to measuring AC/DC voltage, current and resistance levels. It is perfect for professionals who need a combination of accuracy, portability and durability in their meter of choice as well as those who are budget minded but dont want to sacrifice quality or safety features in their purchase decision. Highly recommended!
