The Sonel CMP-200 is a precision AC leakage current clamp meter designed for professional electrical measurements with three selectable ranges: 200 mA, 2 A, and 200 A. This compact instrument delivers measurements with a maximum resolution of 0.1 mA, making it suitable for detecting potential short circuits and monitoring electrical systems to prevent equipment damage. With its 30 mm jaw opening diameter, the clamp allows access to difficult-to-reach conductors while maintaining accurate readings.

The device features a clear 3½-digit LCD display with white backlight illumination for visibility in low-light conditions, along with practical functions including HOLD to freeze measurement results and MAX to capture peak values. Constructed with a durable plastic housing in a grey and orange color scheme, the CMP-200 incorporates a reinforced rotary switch for reliable range selection and an ergonomic rubberized coating that provides a secure grip even when wearing gloves.

At just 1 unit in packaging, this lightweight and portable tool is particularly effective for working in confined spaces where traditional meters may be impractical. Primary applications include leakage current measurements that can identify causes of excessive residual current device tripping, monitoring control circuits, general AC load supervision, and industrial fault finding. The instrument includes automatic power-off functionality to conserve battery life when not in use.

For expanded measurement capabilities, the AC-16 line splitter adapter with 1:1 and 10:1 ratios can be used alongside the clamp meter, supporting measurements up to 230 V AC and 16 A current. This specialized electrical testing device represents a practical solution for technicians requiring reliable current measurement without the bulk of full-sized multimeters, combining essential functionality with compact dimensions for enhanced workplace efficiency.
