精確度

WT5000作為世界上精度高的精度功率分析儀，確?；揪葹?plusmn;0.03%，且在選定電壓和電流量程的1%~130%范圍都能夠保證精度。 WT5000最小化了低功率因數(shù)的影響(視在功率的0.02%)，也能精確測量較大的相移與頻率。

• 交流功率精度：讀數(shù)的0.01%+量程的0.02%
• 直流功率精度：讀數(shù)的0.02%+量程的0.05%
• 10 MS/s 18 bit ADC

多通道測量

測量支持多達(dá)7個不同的功率相，采樣速率達(dá)到10MS/s（18bit）。 10.1英寸的WXGA顯示器具有高分辨率，允許多達(dá)7組的分屏波形顯示，能顯示多至12頁測量參數(shù)，是效率測試的理想之選，適用于變頻器驅(qū)動的電機(jī)、可再生能源技術(shù)以及諸如泵、風(fēng)扇和電動車輛之類的牽引測量。測量數(shù)據(jù)還會即時以矢量格式或趨勢圖顯示。
 

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.

直觀的操作

WT5000支持獨(dú)立的觸屏和硬件按鍵操作，流暢直觀的體驗(yàn)讓連接、配置和測量比以往更簡單。 10.1英寸的WXGA觸屏即使在電機(jī)和變頻器等高噪音環(huán)境中依然保持優(yōu)秀的抗干擾能力。
 

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.

高級濾波

除了低通頻率濾波器和線路濾波器， WT5000還具備高級濾波功能，提供前所未有的控制來精確分析最復(fù)雜的波形。

• 同步源濾波器：與過零點(diǎn)同步方式不同，用戶可以選擇同步源信號的任意點(diǎn)。
• 增強(qiáng)的頻率濾波器：允許用戶同時測量基波和開關(guān)頻率，而不會影響其他參數(shù)。
• 數(shù)字并行濾波器：一個高頻抗混疊濾波器和兩個獨(dú)立的線路濾波器協(xié)力確保正常測量和諧波測量的精確度，并且不會導(dǎo)致寬帶和諧波測量混疊。用戶能夠限制諧波次數(shù)，消除低帶寬測量的衰減。

先進(jìn)的諧波分析

評估和對比變頻器、電機(jī)或功率調(diào)節(jié)器高達(dá)500次的輸入輸出諧波。 WT5000讓用戶不僅能同時測量諧波和功率，還能對比來自兩個不同輸入源的諧波。

由于采用了具備數(shù)字并行通路技術(shù)的抗混疊功能和線路濾波器，可以同時對寬頻成分和窄頻成分進(jìn)行功率分析，所以最大程度地降低了噪音和混疊的影響。

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.

用戶自定義的觸發(fā)和運(yùn)算

根據(jù)應(yīng)用需求定義和使用事件觸發(fā)及自定義運(yùn)算。事件觸發(fā)功能允許用戶設(shè)置限值，捕獲特定功率、電流或其他參數(shù)限值內(nèi)或限值外的讀數(shù)。用戶還可以定義和使用多達(dá)20條不同的表達(dá)式，進(jìn)行自定義運(yùn)算。滿足觸發(fā)條件的數(shù)據(jù)可被存儲、打印或另存到USB存儲設(shè)備。
 

用戶自定義功能

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, “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.
