The operability of the touch panel has been improved. "Time / div" can be set by pinch / out. Also, you can flick the waveform display contents.
Advanced Filtering
In addition to low pass frequency filters and line filters, the WT5000 features advanced filtering capabilities that provide unprecedented control to analyze even the toughest of waveforms with precision.
- Synchronization source filter: Instead of synchronizing to zero crossings, users can select any specific point of the synchronization source signal.
- Enhanced frequency filter: Allows users to simultaneously measure fundamental and switching frequencies without influencing any other parameter.
- Digital Parallel Path filters: Supported by a high frequency anti-aliasing filter, two separate line filters for normal and harmonic measurements ensures accuracy without aliasing in wide band and harmonic measurements. Users can limit the number of harmonic orders to eliminate attenuation in low bandwidth measurements.
Advanced Harmonic Analysis
Evaluate and compare input and output harmonics of inverters, motors or power conditioners up to the 500th order. The WT5000 allows users to not only measure harmonics and power simultaneously but also offers side by side comparison of harmonics from two different input sources.
The effects of noise and aliasing are minimized by antialiasing and line filters with Digital Parallel Path technology allowing simultaneous power analysis of wide band and narrow band components.

Numeric and Waveform Synchronized Data
The waveform data is streamed without any gaps up to 2 MS/s and is synchronized with the numerical data. Abnormal findings in numerical data can be directly linked and be evaluated in the waveform data. For example, one can find numeric parameter variations caused by the influence of imposed high-frequency noise.
Custom Triggers and Computations
Define and use event triggers and custom computations as per application needs. The event trigger function allows users to set limits to capture readings that fall within or outside a specific range of power, current or other parameters. Users can also define and use up to 20 different expressions for custom calculations. Data that meets the trigger conditions can be stored, printed, or saved to a USB memory device.
Follows frequency fluctuations in input signals by auto update mode
This feature can follow fluctuating input frequencies without gaps by changing the data update rate automatically when measuring devices like motors whose input signal frequency fluctuates with changes in rotation speed. It can cover from frequencies as low as 0.1Hz. In addition to constant-interval update mode of 10ms-20s, “Auto update mode”, which updates data in sync with the cycle of input signal, is now available. This new feature is useful for continuous measurement, such as automated testing.
Easy setup menu
Current range, various filters, data update rate, and measurement period can be automatically switched according to the measurement scene.
The measurement scene can be selected from among "50/60Hz," "DC," "PWM," "High Frequency," and "General.
After the automatic setting, the switched items can be checked at a glance and the settings can be easily adjusted.
Wiring with delta conversion useful for motor parameter measurement
When three-phase delta wiring is used, the results of converting to phase voltage using delta-star conversion can be used to measure harmonics, display waveforms on screen, and output data. (When using star connections, it is possible to measure harmonics using the result converted to line voltage using star-delta conversion.)
It can calculate the fundamental wave components of phase voltages required for measuring motor parameters (Ld, Lq), and can be used to evaluate synchronous motors.

Measuring transformer loss helps ensure safer operation and optimizes delivery of electricity. During testing, low power factor signifies high core losses and requires specialty instruments to more accurately measure power.
Range anxiety – the worry that that the battery will run out before a destination or charging point is reached – is among the major barriers for mainstream adoption of electric vehicles. As charging infrastructures still need to be improved, battery efficiency in charging and regenerative braking systems are important.
Maximum torque per ampere (MTPA) is an optimization strategy for the control of electric motors and drives that employ field-oriented control (FOC), particularly with electric vehicles (EVs) and industrial automation applications. The goal of MTPA is to achieve the maximum possible torque output from a motor for a given current input.
Maximum power point tracking (MPPT) charge controllers play a crucial role in the optimization of renewable energy system efficiency and performance. Through dynamic tracking of a renewable energy source’s maximum power point, an MPPT controller enables more efficient energy harvesting, faster charging, and adaptability to changing environmental conditions.
Energy consumption in low-power and standby modes is an important issue due to increased awareness that energy resources are becoming limited and demand for energy-saving household electrical appliances continues to grow. IEC62301 Ed2.0 (2011) and EN 50564:2011 define standby mode as the lowest energy consumption of an appliance not performing its main function, when connected to the mains. IEC62301 Ed2.0 (2011) defines test methods and requirements for both the mains supply and the test equipment. It is crucial that design and test engineers choose highly accurate power measurement tools to confirm that their devices meet these requirements.
