Clamp meter Unit UT213B — digital clamp multimeter, AC current measurement

The Unit Clamp Meter UT213B is a handheld digital clamp multimeter designed for non-contact AC current measurement and basic multimeter functions. It combines a clamp-style jaw for measuring alternating current with voltage, resistance and continuity checks, enabling electricians and technicians to perform quick diagnostics and maintenance without disconnecting conductors. The compact, portable design and clear display make the UT213B suitable for field and workshop use where fast current readings and straightforward electrical checks are required.

Advantages

The clamp jaw allows safe measurement of AC current on live conductors without interrupting the circuit. Integrated multimeter functions provide additional measurements — such as voltage, resistance and continuity — in the same instrument, reducing the need to carry several separate tools. The device is compact and portable, intended for ease of handling during inspections, troubleshooting and routine checks. Its straightforward controls and readable display support efficient, repeatable measurements.

Suitable for

• Measuring AC current on cables and conductors without disconnecting them
• Routine electrical maintenance and load checks in residential and commercial installations
• Troubleshooting circuits and verifying voltage, resistance and continuity
• Field service work where compact, portable measurement tools are required

Key specifications

• Measurement capability: AC current via clamp jaw, plus multimeter functions (voltage, resistance, continuity)
• Form factor: handheld clamp-style meter for non-contact current measurement
• Display: digital readout for numerical results and basic indicators
• Safety: designed for measuring live conductors without disconnection (observe safe working practices and rated category limits)
• Portability: compact and lightweight for field and workshop use

How to use

Place the clamp jaw around a single conductor to measure AC current; ensure the jaw fully encloses only one conductor to obtain a correct reading. Select the required measurement function using the rotary switch or function buttons, and read results on the digital display. For voltage, resistance or continuity checks, follow standard multimeter procedures: connect the test probes to the circuit or component under test and observe polarity and safety warnings. Always follow the instrument’s operating instructions and safety guidelines when measuring live circuits.

Usage recommendations

Before each use, inspect the clamp jaw and probes for damage and verify that the unit is set to the correct measurement mode. Use appropriate personal protective equipment and observe site safety rules when working on live electrical systems. For accurate current readings, clamp only one conductor at a time and avoid placing multiple conductors within the jaw.
