Description
The CM-05 DC/AC Current Probe is designed for technicians who need precise current waveform measurement using oscilloscopes or data loggers. It supports DC and AC current measurement up to 200A, making it suitable for power electronics testing, maintenance work, and laboratory analysis. The probe delivers high-resolution analog output (mV/A) to ensure accurate signal monitoring across multiple current ranges.
The device features manual range selection and a convenient one-touch zero function. This allows users to quickly remove DC offset before measurement, which improves accuracy. With low power consumption of approximately 6 mA, the probe offers efficient battery usage and long operating time. A red LED low battery indicator alerts users when replacement is needed.
Built for field and bench use, the probe includes a 23 mm conductor jaw that fits most cables. It operates reliably from -10°C to 50°C and up to 2000 m altitude. The compact housing (183 × 61.3 × 35.6 mm) and 190 g weight make it easy to carry. The package comes complete with carrying bag, batteries, test leads, and user manual, so users can start measurements immediately.
