Clamp Meter Unit UT205A+ by Unit — digital clamp multimeter, model UT205A+

The Unit UT205A+ clamp meter is a handheld digital clamp multimeter designed to measure AC current without the need to disconnect conductors. It combines a jaw-style current sensor with standard multimeter functions in a compact housing, providing non-intrusive current measurement together with voltage, resistance and continuity checks. The device is suitable for field use by electricians and technicians performing troubleshooting, maintenance and routine inspections.

Advantages

The clamp meter offers safe, contactless AC current measurement through its insulated jaws, reducing the need to interrupt circuits. Its compact size and integrated multimeter functions allow quick switching between current, voltage and resistance measurements. Built-in features such as a clear digital display, data hold and low battery indicator support reliable readings in diverse work environments.

Suitable for

• Measuring AC current in single-phase and multi-conductor installations without disconnection
• Electrical troubleshooting and fault location in residential, commercial and light industrial settings
• Routine maintenance and inspection of motors, lighting circuits and distribution panels
• On-site measurements where portability and non-intrusive testing are required

Key specifications

• Function: AC current measurement with clamp jaw plus standard multimeter functions (voltage, resistance, continuity)
• Display: digital readout with data hold capability
• Measurement method: non-contact clamp-on current sensing for live conductors
• Power: battery-operated for portable field use
• Safety features: insulated clamp jaws and clear indicators for battery and measurement state
• Form factor: compact, handheld design for easy single-handed operation

How to use

Open the clamp jaws and place them around a single conductor to measure AC current, ensuring the conductor is centered within the jaw for the most accurate result. Use the function selector to choose current, voltage or resistance measurement modes as required. Observe the digital display for readings and use data hold to freeze values when needed. Replace the battery when the low battery indicator appears and keep the jaws and sensor area clean and free of debris for reliable operation.

Usage recommendations

For safe and accurate measurements, always verify you are clamping a single conductor rather than a cable bundle, and follow local electrical safety practices including appropriate personal protective equipment. Store the meter in a dry environment and avoid exposure to extreme temperatures or moisture to preserve sensor accuracy.
