Clamp meter BLOW UT-202A+ — digital current clamp meter, AC measurement, compact handheld

The BLOW UT-202A+ is a compact digital clamp meter designed for non-contact AC current measurement and basic electrical checks. Intended for handheld use, it measures alternating current through a clamp jaw and displays results on a clear digital screen. The compact form factor and simple controls make it suitable for troubleshooting, installation and routine maintenance of electrical circuits in residential, commercial and light industrial environments.

Advantages

The clamp meter provides quick, non-invasive AC current readings without disconnecting conductors, reducing downtime during inspections. Its lightweight and compact design allows one-hand operation and easy transport to job sites. The device offers straightforward functionality focused on current measurement and essential checks, providing reliable measurements for on-site verification and basic diagnostics.

Suitable for (tasks / use cases)

• Measuring AC current in single conductors during troubleshooting
• Routine verification of circuit loading and balance
• Field checks during electrical installation and commissioning
• Maintenance inspections in residential and commercial electrical systems
• Quick on-site diagnostics by electricians and service technicians

Key specifications

• Measurement type: AC current via clamp jaw
• Form factor: compact handheld clamp meter
• Display: digital readout for numerical values
• Operation: manual controls suitable for one-handed use
• Portability: lightweight design for transport to job sites

How to use

Position the clamp jaw around a single conductor only, then activate the meter and select the AC current measurement mode. Read the measured value on the digital display once the reading stabilises. Do not clamp around multi-core cables or cables within a sheath that carry opposing currents, as this will produce incorrect readings. Follow standard electrical safety procedures: ensure appropriate personal protective equipment, confirm the environment is safe to work in, and avoid contact with exposed live parts while taking measurements.

Usage recommendations

For accurate results, use the clamp meter on individual conductors and allow the display to stabilise before recording readings. Store the instrument in a dry, dust-free place, and perform periodic visual inspections of the clamp jaw and housing. When measuring in tight spaces, position the meter to maintain single-conductor alignment and avoid adjacent conductors that may affect the measurement.
