Current sensor module with DC power supply
Use of the internal DC power supply for AC/DC current sensors simplifies the preparations before measurement and the measurement setup only requires the current sensor and a connecting cable. Using an external DC power supply and additional wiring is no longer required. There are three sensor connection cable lengths available; i.e., 3 m, 5 m, and 10 m.
*Firmware version 3.01 or later is required.

直观的操作
WT5000支持独立的触屏和硬件按键操作，流畅直观的体验让连接、配置和测量比以往更简单。 10.1英寸的WXGA触屏即使在电机和变频器等高噪音环境中依然保持优秀的抗干扰能力。
Additional Touch Operations
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.
高级滤波
除了低通频率滤波器和线路滤波器， WT5000还具备高级滤波功能，提供的控制来精确分析最复杂的波形。
同步源滤波器：与过零点同步方式不同，用户可以选择同步源信号的任意点。
增强的频率滤波器：允许用户同时测量基波和开关频率，而不会影响其他参数。
数字并行滤波器：一个高频抗混叠滤波器和两个独立的线路滤波器协力确保正常测量和谐波测量的精确度，并且不会导致宽带和谐波测量混叠。用户能够限制谐波次数，消除低带宽测量的衰减。
的谐波分析
评估和对比变频器、电机或功率调节器高达500次的输入输出谐波。 WT5000让用户不仅能同时测量谐波和功率，还能对比来自两个不同输入源的谐波。
由于采用了具备数字并行通路技术的抗混叠功能和线路滤波器，可以同时对宽频成分和窄频成分进行功率分析，所以地降低了噪音和混叠的影响。
Harmonics Regulation Test
Combined with the /G7 option and IEC Harmonic /Flicker measurement software, the WT5000 measured harmonic data can be saved into a PC and tested according to IEC regulations. To support large equipment over 16 A/phase (IEC61000-3-12) the CT200 current sensor model can be used.
Harmonics: EN61000-3-2, IEC61000-3-2, EN61000-3-12, IEC61000-3-12 and JIS C 61000-3-2
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.
用户自定义的触发和运算
根据应用需求定义和使用事件触发及自定义运算。事件触发功能允许用户设置限值，捕获特定功率、电流或其他参数限值内或限值外的读数。用户还可以定义和使用多达20条不同的表达式，进行自定义运算。满足触发条件的数据可被存储、打印或另存到USB存储设备。
用户自定义功能
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, /u201CAuto update mode/u201D, 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.
