Description

AC / DC mA Clamp Meter ( HTC – CL-2055 )

The HTC CL‑2055 Digital Clamp Meter blends precision, portability, and ergonomic design into a dependable tool tailored for electricians, professional technicians, engineers, and electronics enthusiasts. With a sharp four-digit, 9,999-count LCD display, this True RMS clamp meter delivers accurate readings for both AC and DC measurements. Compact and lightweight at just ~180 g, its slim build (approximately 202 × 70 × 34 mm) fits comfortably in one hand, making extended use convenient and fatigue‑free.

At its core, the CL‑2055 safely measures AC/DC current up to 100 A, offering fine resolution of 1 mA. Accuracy is maintained at ±(2.5% + 10 digits) within the 10 A range and ±(4.5% + 10 digits) for 80–100 A, ideal for diagnosing current flow in control circuits, wiring harnesses, or small motors. Supported voltage measurements include DC up to 600 V (accuracy ±1.0% + 2 digits) and AC up to 600 V RMS (accuracy ±1.5% + 5 digits), enabling troubleshooting across both low-voltage electronics and mains-level distribution systems.

The meter also features resistance testing (up to 10 kΩ range with 0.1 Ω resolution) rated at ±1.0% + 3 digits, along with continuity testing that triggers a buzzer under approximately 40 Ω. These functions make it ideal for wiring fault detection, circuit continuity verification, and circuit board diagnostics.

Equipped with True RMS technology, the CL‑2055 accurately measures distorted or non-sinusoidal waveforms that commonly occur with variable-frequency drives or modern power electronics. Its electromagnetic compatibility and full-function overload protection ensure safe and accurate readings across all ranges, preventing damage even in harsh environments.

User-centric features enhance field efficiency. The meter offers auto-ranging for quick setup and peak-hold (MAX) to record the highest-value measurement during testing. Data Hold freezes the reading on display for hands-free reference. Auto power‑off conserves battery life after periods of inactivity, and a low battery indicator alerts users to timely replacement, preventing unexpected power loss.

Additional built-in functions include diode testing, bar-graph display, and a microprocessor-driven sampling rate of about 2 readings per second. This ensures both stable display and responsive feedback during signal fluctuations.

The CL‑2055 is powered by two AAA batteries and includes protective fused input ranges, meeting IEC 61010 CAT II 600 V and CAT III 300 V safety standards. Its rugged, double-molded casing is built to withstand typical workshop and field environments while providing electrical isolation and user safety.

Standard accessories supplied include test leads, a user manual, leather carrying pouch, and batteries—ensuring the meter is ready to deploy straight out of the box. Its compact form factor, safe clamp design, and intuitive interface make it especially well-suited for professionals conducting maintenance and troubleshooting in residential, commercial, or small industrial spaces.
