Power Quality Clamp Meter

The ideal meter for commissioning and troubleshooting modern electrical loads

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.

Applications

Set up and troubleshoot variable frequency drives and UPS systems - Verify correct operation by

measuring key 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

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).

Equipment performance measurement - power consumed by single- and three-phase balanced loads.

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

•

View recorded data in simple graphs and tables.

View waveforms for equipment checking and setup.

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.

Easily customize

the report.
