800A AC / DC Clamp Meter with Temp. & Freq ( HTC – CM-2016 )

Description

The HTC CM‑2016 Digital Clamp Meter is a high-performance test instrument designed for electricians, technicians, HVAC professionals, and industrial service engineers who demand accurate, versatile, and portable measurement tools in the field. Featuring a 3 5/6‑digit (5,999 count) backlit LCD display, this meter delivers high resolution and precise readings across a comprehensive range of functions, making it ideal for electrical diagnostics, maintenance, and troubleshooting.

At its core, the CM‑2016 offers robust True RMS measurement for both AC and DC current. The clamp jaw supports a maximum opening of 28 mm, enabling non-invasive current measurement up to 600 A (DC/AC) with high accuracy. DC current accuracy is ±1.5% +5 digits, while AC current mirrors this performance—ensuring reliable operation in industrial and commercial installations such as motor control panels, HVAC systems, and distribution circuits. Operation is simple, fast, and safe—users can clamp around conductors without interrupting power flow.

Beyond current measurement, the CM‑2016 also accurately measures DC and AC voltage up to 600 V. Voltage ranges include 600 mV, 6 V, 60 V, and 600 V with corresponding resolutions—0.1 mV up to 100 mV. DC voltage accuracy is ±1.0% +5 digits at the lower ranges and ±0.5%+5 digits at mid-range, while AC voltage accuracy is around ±0.8% +5 digits—well-suited for power quality checks and line voltage inspection.

The meter includes a full suite of electrical functions:

• Resistance up to 60 MΩ, in six auto-ranging steps from 600 Ω to 60 MΩ. Resolution ranges from 0.1 Ω to 10 kΩ with accuracy from ±0.8% to ±1.0%+5 digits.

• Capacitance measurement across eight ranges (6 nF up to 6 mF), resolution of 1 pF to 10 µF, and accuracy specifications from ±2.5% to ±5.0% + digits depending on range.

• Frequency/Duty Cycle support up to 10 MHz, with resolution from 0.01 Hz upward and ±0.5% +4 digits accuracy at 10 Hz, scaling with frequency.

• Temperature measurement via a Type-K thermocouple spanning –40 °C to 1000 °C (or –40 °F to 1832 °F). Resolution is 1 °C/°F, with accuracy ±1.0%+5 digits below 400 °C and ±1.5%+15 digits above.

Additional features highlight its usability in real-world conditions:

• Non-Contact Voltage (NCV) detection in 5 ranges for safe live-wire identification.

• A clamp torch light built into the jaws, improving visibility in dim or enclosed spaces.

• Duty cycle and REL (relative) measurement modes, plus Data Hold to freeze display values.

• Polarity indication, auto power‑off after ~15 minutes, and a low‑battery warning (below ~2.6 V).

• Sampling rate of ~3 readings per second, combined with full-range overload protection and a robust double-molded housing.

Safety and portability are key strengths of the CM‑2016. The meter complies with CAT II 600 V / CAT III safety category standards and offers full protection in all measurement ranges. Physically, its form factor (approx. 185 × 65 × 32 mm) and weight (~200 g including two AAA batteries) make it easy to carry and operate one-handed on job sites.

Standard accessories include test leads, a soft carrying case, TP‑04 temperature probe, batteries, and a user manual—ensuring the meter is ready for use right out of the box. Its intuitive rotary switch and familiar layout minimize operator training time.
