Product Description

Fluke 345 Clamp-On Meter Electrical Tester, Watts, Data Logging, 3-Phase Power, Amps AC/DC, Voltage AC/DC, Ohms, Continuity Tester with LCD Display

This clamp on meter is a combination power analyzer, power quality logger, and clamp meter, and is ideal for monitoring electronic loads.

With the bright color power meter display to analyze the harmonic spectrum, a low-pass filter to remove high frequency noise, and a high EMC immunity design, the Fluke 345 power analyzer is ideal for troubleshooting power quality on switching loads. Additionally, the Hall Effect clamp meter design makes measurement of dc current possible without the need to break the circuit with the power meter. The internal memory of the power analyzer enables long-term power quality logging for analysis of trends or intermittent problems.

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

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
