Description
The CM-01 DC/AC Clamp Meter is a versatile diagnostic tool designed for electricians, maintenance engineers, and field technicians. It supports AC/DC current measurement up to 200A, along with voltage, resistance, continuity, and frequency functions, making it suitable for general electrical troubleshooting. The meter provides 10 mA high resolution on the 40A range, allowing precise low-current measurements.
Equipped with a large 3¾-digit LCD and a 40-segment bar graph, the CM-01 updates quickly at 30 times per second, helping users observe transient changes in real time. The one-touch zero function simplifies DC calibration, while Max/Min recording and Data Hold improve measurement convenience. The unit also includes continuity beeper and auto-range frequency measurement for added flexibility.
Designed for field durability, the clamp features a 23 mm conductor capacity and operates from -10°C to 50°C at altitudes up to 2000 m. Its compact body (183 × 63.6 × 35.6 mm) and lightweight 190 g build make it easy to carry into crowded switch boxes and cable areas. The package includes carrying bag, batteries, test leads, and user manual for immediate use.
