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.
