1000A Power Clamp Meter ( HTC – PC-170A )

Description

The HTC PC‑170A Power Clamp Meter is a high‑precision, True RMS clamp meter designed for advanced electrical testing and energy analysis in industrial, commercial, and utility environments. Combining functionality for voltage, current, power, energy, frequency, and power quality metrics, this handheld tool offers power professionals a comprehensive diagnostic platform in one portable package.

At its core, the PC‑170A measures AC current up to 1000 A RMS using a large 55 mm jaw opening, accommodating thick conductors without needing circuit interruption. With True RMS detection for both voltage and current, it ensures dependable readings even with distorted or non-sinusoidal waveforms.

This advanced meter offers full power analysis capabilities, including active power (kW), apparent power (kVA), reactive power (kVAR), power factor (PF), and phase angle (°). Active and apparent power ranges are calibrated from 0.6 kW up to 750 kW, while reactive power covers up to 750 kVAr, with typical accuracy of ±3% + 5 digits and ±4% + 5 digits specifications respectively. Power factor is measurable within a range of 0.3 to 1.0, with a resolution of 0.001 and precision to ±0.022, while phase angle resolution is 1° with ±2° accuracy—useful for diagnosing circuit efficiency, load balance, and power quality.

Voltage measurement capability spans AC voltage ranges of 100 V, 400 V, and 750 V, with a resolution of 0.1 V and accuracy around ±1.2% + 5 digits. Frequency support ranges from 20 Hz to 200 Hz, accurate to ±0.5% + 5 digits, helping users assess the integrity of power supply systems.

In addition to current and voltage, the PC‑170A tracks cumulative active energy usage (kWh) from 1 kWh up to 9999 kWh, with fine 0.001 kWh resolution and ±3% + 2 digits accuracy—ideal for energy audit workflows or peak demand logging.

Controls and display are tailored for professional use. The meter features a large 9999‑count LCD display with backlight, offering crystal‑clear visibility even in dim jobsite conditions. A microprocessor‑driven interface supports auto/manual ranging, data hold, MAX/MIN recording, and memory recall of up to 99 stored readings. Its USB port and bundled software enable seamless data logging, download, and graphing of trends for later analysis on a PC.

Safety and performance are built in: the PC‑170A is designed to IEC CAT III 600 V / CAT IV 300 V standards, with double insulation and overload protection. It samples at approximately three readings per second, balancing responsive updates with stable display accuracy. Engineered for professionals, it is suitable for use in power distribution, industrial control panels, and electrical inspection workflows.

The meter is powered by a standard 9 V (6F22) battery and comes packaged with test leads, USB cable, data‑logging software, and a protective soft carrying case—ensuring complete readiness out of the box. Compact and durable, it measures approximately 295 × 100 × 46 mm, weighs under 400 g, and is ergonomically designed for comfortable one‑handed operation.

This device is ideal for a range of advanced use cases:

• Energy auditing and power quality monitoring in industrial and commercial settings

• Measurement of load profiles and active/reactive power on three‑phase systems

• Evaluation of power factor, efficiency losses, and phase imbalance in HVAC and motor systems

• Real-time logging of current, power, and energy data via USB for analysis

• Troubleshooting of high-current lines without shutting down circuits

Key Feature Summary:

• True RMS voltage and current measurement up to 1000 A through a 55 mm jaw
