High-precision DC current clamp meter. With an operating temperature range of -40 to 120°C and excellent environmental resistance, it outputs measurement values via CAN signals. It is ideal for measuring in actual vehicles.
The CW-402MKII is a high-precision current clamp meter for non-contact DC current measurement. It has a range of ±10A, ±30A, ±50A, and ±150A. With a compact and robust aluminum housing, it is an ideal sensor for use in real vehicle measurements and within temperature-controlled chambers, with an operating temperature range of -40°C to 120°C. It features a built-in temperature sensor that enables advanced temperature compensation and automatic residual magnetism correction, achieving high accuracy. The measured current values are transmitted internally via a CAN bus network. This allows for minimal signal degradation due to EMI and noise, enabling long-distance transmission of measurement values. When combined with a CAN-USB interface device and dedicated software, parameters such as output rate, CAN-ID, bit rate, and averaging of measurement values can be easily configured. Furthermore, multiple clamp sensors can be configured simultaneously, and a common DBC file can be exported.
