• Complete three-phase troubleshooting tool: measures virtually every power system parameter : voltage, current, frequency, power, power consumption (energy), unbalance and flicker, harmonics and inter-harmonics. Captures events like dips and swells, transients, interruptions and rapid voltage changes.
• AutoTrend: no time wasted setting up additional trend graphs while every measurement is automatically recorded. Analyzes trends using cursors and zoom function while recording continues in the background.
• System-Monitor: gives immediate insight into power system’s quality. Checks conformity to limits specified in EN50160 or to own custom limits.
• Four channels: simultaneously measures voltage and current on all three phases and neutral.
• Automatic transient display: captures up to 40 dips, swells, interruptions or transients automatically.
• Meets the stringent 600 V CAT IV, 1000 V CAT III safety standard required for measurements at the service entrance.
• Rugged, handheld instrument operates for more than 7 hours on included rechargeable NiMH battery pack. Menu-driven interface simplifies operation.
• Extensive data analysis possibilities. Cursors and zoom can be used ‘live’ while taking the measurements, or ‘offline’ on stored measurement data. The stored measurements can also be transferred to a PC with FlukeView software (included with Fluke 434).
• Complete package includes everything to get started: 4 current clamps, 5 voltages test leads and clips, line adapter/battery charger and hard case.
• Complies with IEC 61000-4-30 measurement standards.

AutoTrend automatically records all displayed parameters in the background Toggle between data and trend view and use cursors and zoom to analyze measurements without interrupting the recording

Unique AutoTrend gives you fast insight into changes over time. Every displayed reading is automatically and continuously recorded without having to set up threshold levels or interval times, or having to manually start the process. You can quickly view trends in voltage, current, frequency, power, harmonics or flicker on all three phases plus neutral. And you can analyze the trends using the cursors and zoom function – even while background recording continues.

The System-Monitor overview screen gives instant insight into whether the voltage, harmonics, flicker, frequency and the number of dips and swells fall outside the set limits.

With a single push of a button, the unique System-Monitor gives you an overview of power system performance, and checks the compliance of incoming power to EN50160 limits or to your own custom specifications. The overview is shown on a single screen, with color-coded bars clearly indicating which parameters fall outside the limits. A list of each event falling outside these limits is generated.
