• 400 Hz measurement: By increasing the power frequency to 400 Hz, transformers and motors can be much smaller and lighter than at 50 or 60 Hz, which is an advantage in aircrafts, submarines, space crafts, and other military equipment and hand-held tools. The 437 II model captures power quality measurements for these types of avionic and military systems.
• Power inverter efficiency: Simultaneously measure AC output power and DC input power for power electronics systems using optional DC clamp.
• PowerWave data capture: Capture fast RMS data, show half-cycle and waveforms to characterize electrical system dynamics (generator start-ups, UPS switching etc.).
• Energy loss calculator: Classic active and reactive power measurements, unbalance and harmonic power, are quantified to pinpoint the fiscal costs of energy losses.
• Troubleshoot real-time: Analyze the trends using the cursors and zoom tools.
• Highest safety rating in the industry: 600 V CAT IV/1000 V CAT III rated for use at the service entrance.
• Measure all three phases and neutral: With included four flexible current probes with enhanced thin flex design to fit into the tightest places.
• Automatic Trending: Every measurement is always automatically recorded, without any set-up.
• System-Monitor: Ten power quality parameters on one screen according to EN50160 power quality standard.
• Logger function: Configure for any test condition with memory for up to 600 parameters at user defined intervals.
• View graphs and generate reports: With included analysis software.
• Battery life: Seven hours operating time per charge on Li-ion battery pack.

Waveforms for voltage and current are continuously captured for the specified time, and are displayed on screen in high detail; the power waveform is derived from the data. In addition, half-cycle RMS values for voltage, current, power and frequency can be stored and retrieved for analysis. This feature is particularly useful for testing of standby generation systems and UPS systems where reliable switch-on can be vital.
These UPM calculations are used to quantify the fiscal cost of energy loss caused by power quality issues. The calculations are computed, along with other facility-specific information, by an Energy Loss Calculator that ultimately determines how much money a facility loses due to wasted energy.

	Unified Power Measurement Previously, only experts could calculate how much energy was wasted due to power quality issues; utilities could calculate the cost, but the required measurement process was beyond the reach of average electricians. With the new, patented Unified Power function of the 430 Series II, you can use one handheld tool to determine how much power is being wasted, and calculate exactly what the extra consumption costs. Fluke’s patented Unified Power Measurement System provides the most comprehensive view of power available, measuring: Parameters of Classical Power (Steinmetz 1897) and IEEE 1459-2000 Power Detailed Loss Analysis Unbalance Analysis These UPM calculations are used to quantify the fiscal cost of energy loss caused by power quality issues. The calculations are computed, along with other facility-specific information, by an Energy Loss Calculator that ultimately determines how much money a facility loses due to wasted energy.
	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 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.
	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, PF and energy consumption.

Track harmonics up to the 50th, and measure and record THD in accordance with IEC61000-4-7 requirements
