以下是上海四達電子SRC-61數(shù)字鉗形表的產(chǎn)品中英文介紹：

上海四達電子SRC-61數(shù)字鉗形表是一款功能豐富、操作便捷的電工測量工具。它具備多種測量功能，能夠測量直流電壓，量程為1-500V，精度為±(1.5%+3)，輸入阻抗為350KΩ；交流電壓測量量程同樣為1-500V，精度為±(1.8%+3)，輸入阻抗也是350KΩ。在交流電流測量方面，其量程可達500A，精度為±(2.5%+10)。此外，該鉗形表還能測量電阻，量程為10MΩ，不同電阻值范圍的精度有所不同，≤200Ω時精度為±(2.5%+4)，＞200Ω時精度為±(2%+3)。當(dāng)電阻值小于30Ω時，還能通過蜂鳴指示進行導(dǎo)通檢測。

其鉗口設(shè)計合理，能方便地夾持電線進行電流測量，無需切斷電路，大大提高了測量效率和安全性。顯示屏清晰易讀，即使在光線較暗的環(huán)境中也能準(zhǔn)確讀取測量數(shù)據(jù)。外殼堅固耐用，能夠適應(yīng)各種復(fù)雜的工作環(huán)境，無論是室內(nèi)電氣設(shè)備檢測還是戶外電力線路維護，都能可靠地發(fā)揮作用。

The SRC-61 digital clamp meter from Shanghai Sida Electronics is a versatile and user-friendly electrical measurement tool. It boasts a variety of measurement functions. For DC voltage measurement, it has a range of 1-500V with an accuracy of ±(1.5%+3) and an input impedance of 350KΩ. The AC voltage measurement also has a range of 1-500V, with an accuracy of ±(1.8%+3) and the same input impedance of 350KΩ. In terms of AC current measurement, it can measure up to 500A with an accuracy of ±(2.5%+10). Additionally, it can measure resistance with a range of 10MΩ. The accuracy varies depending on the resistance value range: for values ≤200Ω, the accuracy is ±(2.5%+4), and for values >200Ω, it is ±(2%+3). It also features a continuity detection function with a buzzer indication when the resistance is less than 30Ω.

The clamp design is rational, allowing for convenient current measurement by simply clamping around the wire without the need to cut the circuit, which greatly improves measurement efficiency and safety. The display screen is clear and easy to read, ensuring accurate data reading even in low-light environments. The robust casing can withstand various complex working conditions, making it reliable for both indoor electrical equipment inspection and outdoor power line maintenance.
