The Fluke 345 is more than an electric power meter. Combining the functions of a clamp meter, oscilloscope, data logger and digital power meter into one handy device, the Fluke 345 is ideal for working with variable frequency motor drives, high efficiency lighting and other loads using switching electronics.
One of the leading wattage meters of the world, the multi-faceted Fluke 345 is packed with features such as a bright, color display to analyze the harmonic spectrum, a low-pass filter to remove high frequency noise and a high EMC immunity design, making the Fluke 345 power analyzer ideal for troubleshooting power quality on switching loads. The internal memory of this electric power meter enables long-term power quality logging for analysis of trends or intermittent problems. Additionally, the Hall Effect clamp meter design makes measurement of dc current possible without the need to break the circuit.
Features
Besides effectively performing basic tasks like measuring wattage, the Fluke 345 power meters offer the ease of use, portability and flexibility needed to resolve most power issues in commercial, industrial and residential settings.
Applications
Log measured parameters
All voltage, current, power, and harmonic measurements can be logged for minutes, hours, or months. Measurement averaging periods from 1 second to 15 minutes can be selected depending on the application.
Measured parameters can be logged into three separate recording memory areas. If longer recordings are required, the three areas may be combined into one. Stored measurements can be recalled and displayed on-screen in normal screen format or downloaded using the Power Log software package.
Flexible and easy to use
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).
Inrush current
Diagnose equipment start-ups with the inrush current mode. A current trigger level is set prior to recording. Once the level has been exceeded, the meter will begin capture. Recordings from 3 seconds to 300 seconds may be captured, and up to 1000 inrush events may be stored in the instruments memory.
Screen captures and data logging
Any measurement can be stored in memory for later viewing, or downloaded to a PC. Simply press ‘SAVE' to capture the active screen to memory - up to 50 screen shots can be saved for quick and simple documentation. Additionally, over 150,000 individual measurements can be logged for later review on the display or on a PC using Power Log software.
Analysis and reporting software
Designed to quickly view recorded data, the included Power Log software displays all recorded parameters on interactive trends. Generate professional reports with the ‘Report Writer' function, or copy and paste images into report document manually.
