The UNI-T UT258A is a 10,000-count, auto-ranging AC/DC leakage current clamp meter designed for precise low-level measurements. Key specs include a 0mA to 60.0A AC/DC range, 1mA resolution, a 7mm jaw diameter. It features RS-232 data transmission, 99-group data storage, and automatic zeroing.
UT258A is well designed for on-line measurement of DC/AC leakage current and current below 600V, which adopts latest CT and digital integration technology. Slender clamp is very suitable for places full of concentrated cables (such as, electric power metering system, high-speed rail system, automobile circuit maintenance and so on). Non-contact measurement ensures operation safety. The meter has mini shape with high accuracy, stable performance and perfect functions.
Key Functions:
Auto Range: Yes
Data Hold: Yes
Auto Power Off: 5 minutes
Zero Adjustment: Yes (to remove residual magnetism)
The device is ideal for applications requiring high sensitivity in tight spaces, such as measuring leakage current in electrical, communication, and industrial systems.
