臺(tái)灣泰仕PROVA400交直流瓦特鉗表是一款功能強(qiáng)大的電力測(cè)量工具，廣泛應(yīng)用于工業(yè)、商業(yè)和科研領(lǐng)域。它采用先進(jìn)的真均方根值（True RMS）技術(shù)，能夠精確測(cè)量交流和直流的功率、電流和電壓。該鉗表的交流功率測(cè)量范圍可達(dá)240kW，電流測(cè)量范圍為交流和直流400A，電壓測(cè)量范圍為交流400V和直流600V，可滿足多種復(fù)雜環(huán)境下的測(cè)量需求。

PROVA400的設(shè)計(jì)注重實(shí)用性和便攜性。其鉤部尺寸最大可達(dá)23mm，能夠輕松夾持較粗的導(dǎo)線，測(cè)量導(dǎo)線線徑可達(dá)23mm。鉗表采用3 3/4 LCD帶模擬線段圖的顯示方式，使讀數(shù)更加直觀清晰。此外，該設(shè)備還具備手動(dòng)范圍選擇功能，以及過(guò)載警示功能，當(dāng)測(cè)量值超過(guò)量程時(shí)，最左邊一位數(shù)字會(huì)閃動(dòng)，提醒用戶注意。

在性能方面，PROVA400表現(xiàn)出色。其取樣率為每秒2次（數(shù)字）和每秒20次（模擬線段圖），能夠快速準(zhǔn)確地捕捉電力參數(shù)的變化。設(shè)備的工作溫度范圍為-10℃至50℃，工作濕度小于85%（相對(duì)濕度），儲(chǔ)存溫度和濕度分別為-10℃至50℃和小于75%（相對(duì)濕度），適應(yīng)各種惡劣環(huán)境。此外，該設(shè)備的消耗電流約為10mA，使用9號(hào)AA電池，方便用戶在無(wú)電源的場(chǎng)合使用。

PROVA400的尺寸為183mm（長(zhǎng)）×63.6mm（寬）×35.6mm（高），重量?jī)H為190克（含電池），便于攜帶和操作。其附件包括皮袋、說(shuō)明書和兩節(jié)1.5V電池，為用戶提供了完善的使用體驗(yàn)。

The Taiwan TES PROVA400 AC/DC Watt Clamp Meter is a powerful electrical measurement tool widely used in industrial, commercial, and scientific research fields. It employs advanced True RMS technology, enabling precise measurement of AC and DC power, current, and voltage. The clamp meter has an AC power measurement range of up to 240kW, with current measurement ranges of 400A for both AC and DC, and voltage measurement ranges of 400V for AC and 600V for DC. This makes it suitable for a variety of complex measurement scenarios.

The PROVA400 is designed with practicality and portability in mind. Its jaw size can reach up to 23mm, allowing it to easily clamp onto thicker wires, with a maximum wire diameter for measurement of 23mm. The clamp meter features a 3 3/4 LCD display with an analog bar graph, making readings more intuitive and clear. Additionally, the device has a manual range selection function, as well as an overload warning function. When the measured value exceeds the range, the leftmost digit will flash, alerting the user.

In terms of performance, the PROVA400 is outstanding. Its sampling rate is 2 times per second (digital) and 20 times per second (analog bar graph), allowing it to quickly and accurately capture changes in electrical parameters. The device operates within a temperature range of -10℃ to 50℃, with a relative humidity of less than 85%. The storage temperature and humidity are -10℃ to 50℃ and less than 75%, respectively, making it suitable for various harsh environments. Additionally, the device has a low current consumption of approximately 10mA and uses 9V AA batteries, making it convenient for use in locations without power sources.

The PROVA400 has compact dimensions of 183mm (length) × 63.6mm (width) × 35.6mm (height), and weighs only 190 grams (including batteries), making it easy to carry and operate. The package includes a carrying case, user manual, and two 1.5V batteries, providing a complete user experience.
