The CA-600 is an AC/DC current clamp transducer. This device converts any DMM to a current clamp. The transducer measures the current without the need to disconnect the circuit. The device consist of a dual hall-effect sensors. The direct current has an accuracy of ±2%+2 A while the alternate current has ±3%+2 A. The transducer can use any multi-meter with a 200 mV or 2 V range. The series consists of a zero adjustment knob to compensate the hysteresis effect. The transformer has a ratio of 1000:1. The device consist of an indicator for low battery.
