Product Overview
The UNI-T UT211A and UT211B are compact digital clamp meters engineered for high reliability and safety. These instruments feature automatic measurement, a small form factor, and the capability to accurately measure small signal currents with a resolution of up to 0.1 mA. They are designed with a VFC (Variable Frequency Drive) start mode and a specific filter circuit to mitigate high-frequency interference, ensuring precise measurements in environments with VFC conversion voltage or current.
Key Features and Safety
Adhering to international safety standards such as IEC/EN61010-1 and EN61010-2-30, these clamp meters are built with full-range overload protection. Users are advised to read the operation manual thoroughly and comply with all safety instructions, including wearing appropriate personal protective equipment and avoiding use in circuits exceeding 600V or 400Hz. The meters are rated for CATII 600V/CATIII 300V, with pollution class 2.
Key operational features include:
- AC/DC Voltage and Current measurement
- Resistance, Diode, and Capacitance testing
- Frequency measurement (Hz)
- Non-Contact Voltage (NCV) detection
- Data Hold and Backlight functions
- Automatic ranging and zeroing capabilities
Technical Specifications
The UT211A/B models offer a maximum display of 6,000 counts with a measurement update rate of 2-3 times per second. They feature automatic range selection and polarity indication. The clamp opening is designed for wires up to 17mm, and the device operates on two 1.5V AAA batteries. The product is identified with CE certification.
