Clamp Meter Unit 200A Model UT210B — AC current 200 A, clamp-type measurement

Unit 200A AC Clamp Meter UT210B is a handheld clamp-type measuring instrument for non-contact measurement of alternating current up to 200 A. The device features a hinged jaw that allows quick clamping around a conductor to obtain real-time AC current readings. Compact and lightweight, the clamp meter is intended for field use including troubleshooting, load checks and routine electrical maintenance in residential, commercial and light industrial environments.

Advantages

The UT210B delivers fast AC current measurement without interrupting the circuit thanks to its clamp jaw design. Its compact form factor and single-handed operation make it convenient for confined spaces and on-site service calls. The meter provides clear numeric readouts and stable readings for effective fault finding and load verification. The tool is designed for durability and frequent use in typical electrician and HVAC technician workflows.

Suitable for (tasks / use cases)

• Measuring alternating current in single conductors without disconnecting the circuit
• Routine electrical maintenance and load checks on household and commercial circuits
• Field troubleshooting and verification of circuit current for electricians and HVAC technicians
• Quick on-site inspections where portability and ease of use are required

Key specifications

• Measurement type: AC current via clamp jaw
• Maximum measurable current: 200 A AC
• Form factor: handheld, clamp-style meter with hinged jaw
• Display: numeric readout for real-time current values
• Operation: single-handed clamping and measurement
• Intended use: non-contact current measurement for troubleshooting and maintenance

How to use

Power the clamp meter according to the manufacturer instructions and ensure the display is readable. Open the hinged jaw, place the conductor to be measured centrally within the jaw opening and close the clamp fully around the conductor. Read the AC current value directly from the display. For accurate measurements, measure one conductor at a time and avoid clamping around multi-conductor cables that contain both live and neutral conductors simultaneously. Observe standard electrical safety procedures while working near live circuits.

Usage recommendations

Use the clamp meter for quick current checks and troubleshooting on single conductors, and combine measurements with voltage or continuity checks using appropriate instruments when diagnosing complex electrical issues. Store the meter in a dry, dust-free place and inspect the jaw and housing regularly for signs of wear.
