## Summary description

The Uni-T UT221 is a professional digital clamp meter designed for accurate measurement of AC and DC current. This reliable testing tool is essential for electrical maintenance, troubleshooting, and industrial applications. It features a robust design, high-precision sensors, and an easy-to-read display, ensuring efficient performance for electricians and technicians working with complex electrical systems.

## Long description

The Uni-T UT221 is a professional digital clamp meter engineered for the precise measurement of high AC and DC currents up to 2000 A. Designed for demanding industrial environments and electrical maintenance, this robust tool provides the accuracy and reliability required by technicians and electricians. With its wide jaw opening and advanced measurement capabilities, it serves as an essential instrument for troubleshooting complex electrical systems and monitoring high-power circuits.
Advantages
This clamp meter stands out due to its ability to handle high current ranges while maintaining high precision. The inclusion of True RMS technology ensures accurate readings even in non-sinusoidal electrical environments. Users benefit from a comprehensive feature set that includes a low-pass filter for noise reduction, inrush current measurement for motor startup analysis, and a 66-segment analog bar graph that provides a visual representation of fluctuating signals. The device is built for durability and ease of use, featuring automatic range switching and a clear, high-resolution display that simplifies data interpretation in various lighting conditions.
Suitable for
Industrial electrical maintenance and troubleshooting
High-current power distribution system monitoring
Motor startup current analysis using the inrush function
General electrical testing including voltage, resistance, and frequency
Field service work requiring a portable and reliable measurement tool
The device may not be suitable for low-current electronics repair where high sensitivity at the milliampere level is required. Additionally, its physical size and 63 mm jaw opening make it less convenient for use in extremely cramped electrical panels or for measuring very thin, delicate wiring.

How to use
To begin, insert the provided 9V battery into the compartment. Select the desired measurement function using the rotary dial. For current measurements, open the clamp jaws and enclose a single conductor; ensure the jaws are fully closed for accurate readings. For voltage or resistance, connect the test leads to the appropriate input terminals and touch the probes to the circuit points. Use the Data Hold or MAX buttons to capture readings during testing. Always ensure the device is set to the correct mode before making contact with live circuits.
What to consider before purchase
Verify that the 63 mm jaw opening is sufficient for the diameter of the cables you intend to measure.
Ensure the device's current range meets the requirements of your specific industrial or electrical applications.
Consider the physical dimensions and weight if you require a highly portable tool for frequent travel.
Check that the measurement functions, such as True RMS and inrush current, align with your diagnostic needs.
Usage recommendations: Always inspect the test leads for damage before use. When measuring high currents, ensure the conductor is centered within the clamp jaws to minimize errors. Store the device in the provided carrying case when not in use to protect the sensors and display from dust and mechanical impact.
