The Fluke 434 and 435 three-phase power quality analyzers help you locate, predict, prevent and troubleshoot problems in three- and single-phase power distribution systems. Troubleshooting is faster with on-screen display of trends and captured events, even while background recording continues. The new IEC standards for flicker, harmonics and power quality are built right in to take the guess work out of power quality • Troubleshoot real-time: Analyze the trends using the cursors and zoom tools-even while background recording continues • Highest safety rating in the industry: 600 V CAT IV/1000 V CAT III rated for use at the service entrance • Automatic Transient Mode: Capture 200 kHz waveform data on all phases simultaneously up to 6 kV • Fully Class-A compliant: Conduct tests according to the stringent international IEC 61000-4-30 Class-A standard • Measure all three phases and neutral: With included four current probes • AutoTrend: Every measurement you see is always automatically recorded, without any setup • System-Monitor: Up to seven power quality parameters on one screen according to EN50160 power quality standard • Inrush mode: For troubleshooting nuisance circuit breaker tripping • View graphs and generate reports: With included analysis software • Logger function: Configure for any test condition with memory for over 400 parameters at user defined intervals • Mains signaling: Measure interference from ripple control signals at specific frequencies • Battery Life: Seven hours operating time per charge on NiMH battery pack
