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.
The Fluke 435 features 0.1 percent voltage accuracy making it fully compliant with the IEC 61000-4-30 Class A standard
Logger function: record the detail you need. Detailed, user-configurable long-time recording gives you the MIN, MAX and AVG readings of up to 100 parameters on all 4 phases with selectable averaging time down to 0.5 seconds. Enough memory is available to record 400 parameters with 1 minute resolution for up to a month.
Four channels: simultaneously measures voltage and current on all three phases and neutral.
AutoScaling: easier trend analysis with automatic scaling of the vertical axis you will always use the full display to view the waveforms.
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 435 and 434).
The Fluke 435 comes with Power log software to analyse recorded data and to create reports.
Complete package includes everything to get started: 4 current clamps, 4 flex clamps with Fluke 435, 5 voltage test leads and clips, line adapter/battery charger and hard case.
Complies with IEC 61000-4-30 measurement standards
AutoTrend - Quickly see the trend
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.
AutoTrend automatically records all displayed parameters in the background.
SystemMonitor - Check performance against EN50160 with ease
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.
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. A detailed list is given of all events falling outside the set limits.
Logging function allows you to customize measurement selections and provides instantaneous analysis of user-selectable parameters. Measure and record power (W), VA and VARs. The 434 adds the ability to record energy consumption. Track harmonics up to the 50th, and measure and record THD in accordance with IEC61000-4-7 requirements
