The CP9000LF series flexible current probe is a low-frequency flexible probe with a dual-range design. It can achieve a wide current measurement range, ranging from 60A to 60kA. The accuracy is guaranteed to be 1% at the center of the loop, and the typical accuracy within the entire loop (except at the loop junction) is 2%. The bandwidth is up to 600kHz (with 700mm coil circumference) or 1MHz (with 300mm coil circumference). The typical outer diameter of the probe loop is 8mm, and the withstand voltage is up to 10kVpk, making it ideal for low-frequency, high-current, and high-power testing scenarios. Its main features include: a lightweight and flexible coil that is easily detachable, allowing it to reach areas inaccessible to many rigid probes and enabling easy connection to the measured object; insertion loss is almost zero, only a few pH, resulting in nearly zero interference to the measured object; a standard BNC output interface, facilitating connection with oscilloscopes, data loggers, digital voltmeters, etc., for observing current waveforms; powered by a 9V battery or an external 12V DC power supply, making it more flexible and convenient to use; an overcurrent alarm function, featuring a more user-friendly design; the length of the probe loop and connecting cable can be customizable according to customer requirements to meet testing requirements in special scenarios.
