  • 1 - C430 Hard carrying case with clamp holders
  • 4 - i400s current clamps
  • 1 - TLS430 Test leads and alligator clip set (4 black, 1 green)
  • 1 - BP190 NiMH Battery pack (installed)
  • 1 - BC430 Battery charger/line voltage adapter
  • 1 - SW43W FlukeView software
  • 1 - OC4USB Serial Interface adapter/cable (USB)
  • 1 - WC100 Color localization set
  • 1 - Getting Started (printed)
  • 1 - User Manual (CD-ROM)
CAT IV 600 V and CAT III 1000 V safety rating

Designed to help protect you and your equipment against electrical shock and fire, the Fluke 430 Series analyzers, accessories and charger are all certified to meet the stringent safety standards for use in CAT IV 600 V and CAT III 1000 V environments. They are the first tools of their kind to carry the CAT IV rating and therefore can be used at virtually all power connections and outlets in a low-voltage power distribution systems.

Quickly see the trend
Auto Trend feature allows fast insight into changes over time. Every displayed reading is automatically and continuously recorded without having to set thresholds or intervals and without manually starting the process. Quickly view trends for voltage, current, frequency, power, harmonics or flicker on all phases and neutral. Analyze the trends using the cursors and zoom tools тАФ even while background recording continues.

Measures everything
Measure true-rms & peak voltage and current, frequency, dips and swells, transients, interruptions, power and power consumption, peak demand harmonics, inter-harmonics, flicker and unbalance.

Automatic transient display
Every time an event or distortion on voltage is detected, the instrument triggers and automatically stores voltage and current waveforms on all three phases and neutral. The analyzer will also trigger when a certain current value level is exceeded. Up to 40 dips, swells, interruptions and transients can be captured this way. You can see voltage transients as high as 6 kV and as fast as 5 microseconds.

System-Monitor: Multi-parameter power
quality health check on one display A single push of the MONITOR button delivers a single dashboard display of rms voltage, harmonics, flicker, interruptions, rapid voltage changes, swells, unbalance and frequency. The dashboard is updated live, showing compliance of each parameter to EN50160 limits or your own limits. Color-coded bars clearly show which parameters are inside (pass) or outside limits (fail). During a Monitor session, you can easily drill down to more detail of any parameter and view and capture its trends for a report.

Extensive data analysis possibilities
The Fluke 434/003 provides three ways to analyze measurements. Cursors and zoom tools can be used 'live' while taking measurements or 'off line' on stored measurement data. The stored measurements can also be transferred to a PC with FlukeView® software. The software's 'view' mode allows cursors and zoom tools to be used on stored measurements. Perform custom analysis and create reports, measurement data can also be exported to common spreadsheet programs. Store up to 10 measurement datasets, each dataset can contain up to 32 parameters and up to 50 screens for use in reports.

Thanks to thoughtful features like user-friendly menus in local languages and setups with minimal steps. The high-resolution color screen updates every 200 mS and displays waveforms and wiring diagrams color coded to industry standards. Handy on-screen wiring diagrams for all commonly used three phase and single phase configurations guide you through connections.
