Fluke 345

Power Quality Clamp Meter

With a bright color display to analyze the harmonic

spectrum, a low-pass ﬁlter to remove high frequency noise,

and a high EMC immunity design, the Fluke 345 is ideal for

measurements on switching loads such as variable frequency

drives, electronic lighting and UPS systems. Additionally, the

Hall Effect measurement system makes measurement of dc

current possible without the need to break the circuit, and

the internal memory enables long-term logging for analysis of

trends or intermittent problems.

Flexible and easy to use The 345 measures a wide range of electrical parameters and can be used for many applications in today’s modern electrical environment. Measuring mode is selected by a simple turn of the rotary switch and the large color display presents data in a clear, easy-to-understand way. By default the display will show the most common measurements, in very large format. If more detailed views are required they are available with the press of a single key (up to six measurements at once).
