• 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(cè)量

測(cè)量支持多達(dá)7個(gè)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(yè)測(cè)量參數(shù)，是效率測(cè)試的理想之選，適用于變頻器驅(qū)動(dòng)的電機(jī)、可再生能源技術(shù)以及諸如泵、風(fēng)扇和電動(dòng)車(chē)輛之類的牽引測(cè)量。測(cè)量數(shù)據(jù)還會(huì)即時(shí)以矢量格式或趨勢(shì)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(cè)量比以往更簡(jiǎn)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(jí)濾波

除了低通頻率濾波器和線路濾波器， WT5000還具備高級(jí)濾波功能，提供的控制來(lái)精確分析最復(fù)雜的波形。

• 同步源濾波器：與過(guò)零點(diǎn)同步方式不同，用戶可以選擇同步源信號(hào)的任意點(diǎn)。

• 增強(qiáng)的頻率濾波器：允許用戶同時(shí)測(cè)量基波和開(kāi)關(guān)頻率，而不會(huì)影響其他參數(shù)。

• 數(shù)字并行濾波器：一個(gè)高頻抗混疊濾波器和兩個(gè)獨(dú)立的線路濾波器協(xié)力確保正常測(cè)量和諧波測(cè)量的精確度，并且不會(huì)導(dǎo)致寬帶和諧波測(cè)量混疊。用戶能夠限制諧波次數(shù)，消除低帶寬測(cè)量的衰減。

的諧波分析

評(píng)估和對(duì)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(shí)測(cè)量諧波和功率，還能對(duì)比來(lái)自兩個(gè)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(shí)對(duì)寬頻成分和窄頻成分進(jìn)行功率分析，所以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(chǔ)、打印或另存到USB存儲(chǔ)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, /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.
