Fluke 345 Offers

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

  • AC/DC current: Clamp-on measurement of ac current up to 1400 A rms and dc current up to 2000 A without breaking the circuit
  • Highest safety rating: 600 V CAT IV power analyzer is rated for use at the service entrance
  • Accurate in noisy environments: Clamp meter performs even with distorted waveforms present on electronic
  • loads with low-pass filter
  • Data logging: Identify intermittent faults by logging any power quality parameter for minutes, or over a month, including harmonics
  • Verify batteries: Direct measurement of dc ripple (%) for battery and dc systems
  • Troubleshoot harmonics: Analyze and log harmonics digitally or graphically
  • Inrush current: Capture and analyze nuisance tripping, from 3 seconds to 300 seconds
  • Easy to use: Easily confirm power meter setup with large backlit color display of waveforms and trends
  • USB download: Download logged data with PowerLog application software to view trends and screenshots, analyze and create reports simply.
  • Battery eliminator: powers the instrument when pefroming extended logging sessions.
  • 3-Phase power: Built in capability for balanced loads
  • View graphs and generate reports: Use power analyzer with included Power Log software

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

  • Setup and troubleshoot variable frequency drives and UPS systems - Verify correct operation by measuring key power quality parameters
  • Harmonics measurements - Uncover harmonic issues that can damage or disrupt critical equipment
  • Inrush capture - Check start-up current where spurious resets or nuisance circuit breaker tripping occurs
  • Load studies - Verify electrical system capacity before adding loads

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.

  • Easy-to-use tabbed window format allows quick data evaluation.
  • One-step download and display capability
  • Waveform, harmonics, and trend download
  • Simple data export to other applications

Webinar: Introduction to Portable Precision Power Analyzers with Fluke


This wideband precision analyzer is accurate enough for the lab, yet it's built for the field. Offering you more freedom than ever before to make high accuracy power measurements wherever you need to. Whether in the lab, or in the field. Designed for portability and eliminates the need to carry large, fragile, expensive analyzers into the field, allowing you to make measurements directly at the load in nearly any environment. By measuring directly at the load, you can discover how the equipment operates under real-world conditions, with real-world variables, not just at a test bench or in the lab.
During our 1-hour webinar, we've covered:
- The new Fluke Norma 6000 Power Analyzer for accurate measurements at frequencies from DC to 500kHz.
- It is not a Power Quality Analyzer.
- It is a Power Analyzer for accurate measurements at frequencies from DC to 500kHz.
- It is designed to be used in the field, its rugged, battery-operated, lightweight, and suited to use outside of a laboratory environment.
- You’ll learn why it can help you, where and how it is used.

Webinar: Introduction to Portable Precision Power Analyzers with Fluke


This wideband precision analyzer is accurate enough for the lab, yet it's built for the field. Offering you more freedom than ever before to make high accuracy power measurements wherever you need to. Whether in the lab, or in the field. Designed for portability and eliminates the need to carry large, fragile, expensive analyzers into the field, allowing you to make measurements directly at the load in nearly any environment. By measuring directly at the load, you can discover how the equipment operates under real-world conditions, with real-world variables, not just at a test bench or in the lab.
During our 1-hour webinar, we've covered:
- The new Fluke Norma 6000 Power Analyzer for accurate measurements at frequencies from DC to 500kHz.
- It is not a Power Quality Analyzer.
- It is a Power Analyzer for accurate measurements at frequencies from DC to 500kHz.
- It is designed to be used in the field, its rugged, battery-operated, lightweight, and suited to use outside of a laboratory environment.
- You’ll learn why it can help you, where and how it is used.
