1000A AC / DC Clamp Meter with Temp. & Freq ( HTC – CM-2056 )

Description

The HTC CM‑2056 1000 A AC/DC Clamp Meter is a high-performance test instrument tailored for professional electricians, engineers, and technicians who demand precision, safety, and versatility in demanding environments. With its robust functionality and advanced measurement capabilities, the CM‑2056 is ideally suited for industrial maintenance, HVAC diagnostics, residential wiring work, and general electrical inspections.

At its core, the CM‑2056 features True RMS technology for accurate AC and DC current measurements up to ±1000 A, even in the presence of non-linear or distorted waveforms. Its 52 mm clamp jaw allows non-intrusive testing on conductors without disconnecting circuits, making it an essential tool for analyzing motor loads, distribution panels, and power systems.

This clamp meter is more than just a current tester—it functions as a comprehensive multimeter, offering DC voltage measurement from 400 mV to 1000 V, with accuracy of ±(0.5% + 5 digits), and AC voltage measurement up to 750 V with accuracy of ±(1.0% + 5 digits). These capabilities make it well-suited for both delicate electronic circuitry and high-voltage installations.

In addition to voltage and current, the CM‑2056 supports resistance testing from 400 Ω to 40 MΩ with resolution down to 0.1 Ω and accuracy of ±(0.8% + 3 digits). It provides reliable diagnostics for wiring continuity, component integrity, and circuit fault detection. The meter also measures capacitance from 40 nF to 100 µF, frequency from 10 Hz to 10 MHz, and temperature from –40 °C to 1000 °C (using the included K-type probe), offering accuracies ideal for professional testing applications.

Other multi-function capabilities include diode testing, continuity checks, and advanced functions like MAX/MIN recording, data hold, and relative measurement. These features enable detailed waveform and fault analysis in dynamic testing environments.

Designed with usability and safety in mind, the CM‑2056 includes features like a large 3¾‑digit, 3,999‑count LCD display with backlight for visibility in dimly lit areas. A built-in clamp torch further aids in working under low-light conditions. The meter offers safety features such as over-range indication, overload protection, and compliance with CAT III 600 V standards.

Ergonomics and portability are also prioritized—measuring approximately 270 × 123 × 35 mm and weighing around 280 g, the unit is lightweight and convenient for field or workshop use. It is powered by two AAA 1.5 V batteries, delivering long operational life thanks to an auto-shutoff function and low-battery alert.

Each unit comes fully equipped with test leads, a temperature probe, user manual, battery, and a soft carrying case, making it ready to use immediately out of the box. Making it suitable for bulk procurement by training institutes, service centers, or corporate maintenance teams.

With its broad range of measurable parameters—AC/DC voltage up to 1000 V, AC/DC current up to 1000 A, resistance to 40 MΩ, capacitance up to 100 µF, frequency to 10 MHz, and temperature up to 1000 °C—the CM‑2056 is the ultimate utility tool for electrical professionals. It streamlines complex testing needs into a single, high-accuracy instrument.

In summary, the HTC CM‑2056 1000A AC/DC Clamp Meter is a durable, versatile, and safety-certified tool offering a full suite of diagnostic capabilities in a compact form. Its True RMS measurement, wide jaw clamp, temperature sensing, and multi-parameter functions make it ideal for electricians, HVAC engineers, maintenance personnel, and technicians looking for precision, dependability, and convenience in one meter.
