Current Sensor Phase Shift

Current sensor phase shift is essential especially in high current situations in order to achieve optimal measurement precision. Current sensors typically exhibit gradually increasing phase error in the high-frequency region due to the characteristics of the sensor’s magnetic core and circuitry. Furthermore, differences in the design of various sensor models cause the magnitude of this error to vary. The PW6001’s current sensor phase shift function uses sensor-specific phase error information to correct for error, thereby improving phase characteristics in the high-frequency region and reducing power measurement error. Phase shift correction is conducted with a 0.01° resolution in order to measure power even more accurately.

0.1 Hz to 2 MHz frequency bandwidth

Power measurements across wide bandwidths are required for supporting high-speed switching devices such as SiC. Compared even to the Hioki 3390 Power Analyzer, the PW6001 is engineered with 10x the frequency band and sampling performance. High accuracy, wideband, and high stability. The Hioki PW6001 combines the 3 important elements of power measurement and basic performance backed by advanced technology to achieve unsurpassed power analysis.

High-speed sampling of 5 MS/s for true frequency analysis

Measurements based on sampling theorem are required to perform an accurate power analysis of PWM waveforms. The Hioki PW6001 features direct sampling of input signals at 5 MS/s, resulting in a measurement band of 2 MHz. This enables analysis without aliasing error

Fast, simultaneous calculation functions achieved with Power Analysis Engine II

All measurements, including period detection, wideband power analysis, harmonic analysis, and waveform analysis, are digitally processed independently and with no effect on each other. Fast calculation processing is used to achieve a data update speed of 10 ms while maintaining maximum accuracy.

Strengthened resistance to noise and temperature fluctuations in the absolute pursuit of measurement stability

The custom-shaped solid shield made completely of finely finished metal and optical isolation devices used to maintain sufficient creepage distance from the input terminals dramatically improve noise resistance, provide optimal stability, and achieve a CMRR performance of 80 dB/100 kHz. Add the superior temperature characteristics of ±0.01%/°C and you now have access to a power analyzer that delivers top-of-the-line measurement stability.

Analyze waveforms without an oscilloscope

In addition to voltage and current waveforms, torque sensor and encoder signals can also be displayed simultaneously. The PW6001 is also built in with triggers, pre-triggers, other triggers convenient for motor analysis such as for PWM waveforms, as well as encoder pulse triggers.

Harmonic analysis up to 1.5 MHz

Wideband harmonic analysis is provided as a standard feature to a max. 100th order for fundamental frequencies 0.1 Hz to 300 kHz and an analysis band of 1.5 MHz. Analysis of fundamental waves in motors and measurement of distortion rate in the transmission waveforms for wireless power supplies are now possible.

FFT analysis of target waveforms

Frequency analysis up to 2 MHz. Specify any waveform analysis range you like and see the 10 highest peak values and frequencies displayed.

Digital LPF for displaying the waveform you want to view

Select a cutoff frequency for the measurement target. Digital LPF greatly reduces noise to let you display the waveform you want to view.

Seamless operability

Time spent on operations is reduced, to allow focused concentration on analysis. -9-inch touch screen with soft keypad -Dual knobs for vertical/horizontal manipulation of waveforms -Wiring confirmation function, to avoid wiring mistakes -Enter handwritten memos on the screen, or use the onscreen keypad

One-touch settings take you to measurement immediately

The built-in easy setup function allows you to simply select the type of measurement line and immediately start measurement using the automated optimum settings.

DC accuracy is indispensable for achieving correct efficiency measurements

For example, when measuring the efficiency of a DC/AC converter, not only AC accuracy but also DC accuracy are equally important. With the PW6001, a DC measurement accuracy of ±0.02% rdg. ±0.05% f.s.* delivers correct and stable efficiency measurements. *Unit accuracy only

Specially designed for current sensors to achieve highly precise measurement

This reduces the effects of wiring and meter loss, allowing measurements with wiring conditions that are close to the actual operating environment for a highly efficient system. - Short wiring - Little effect from routing - Small insertion loss

High-accuracy clamp current sensor

The CT684x series feature broad temperature characteristics and an operating temperature range of -40°C to 85°C, allowing them to be used in operational evaluations of devices and inside equipment that are subject to extreme temperature changes. The current sensors’ tough performance helps ensure you can make the measurements you need.

Get a combined accuracy of ±0.075% rdg. with CURRENT BOX PW9100

Add ±0.05% rdg. accuracy of the current sensor to the PW6001’s basic accuracy of ±0.025% rdg. to achieve accuracy of ±0.075%. Choose from a diverse array of sensors to cover very small currents from 10mA up to large 2000A* loads. *Effective measurement range.

Wideband current probes supported

When combined with the HIOKI wideband current probes, it is also possible to measure minute currents of 0.5 mA. This is perfect for observing leakage current waveforms in inverters. ・CT6700CT6701 1mA〜 ・CT6710CT6711 0.5mA〜

Newly developed opposed split coil technology is used in winding (CT) areas, achieving a wide measurement range from DC to 4MHz. The CT6904 makes it a world-class current sensor that provides the ultimate level of performance when used in conjunction with the Power Analyzer PW6001. (The sensor is also available in an 800A rated version.)
