CURRENT CUTTER UNI-T UT201+ — digital measuring instrument with True RMS technology, designed to measure AC current without breaking the electrical circuit, as well as DC and AC voltage, resistance, diode test and circuit integrity. The UNI-T UT201+ model is equipped with a non-contact NCV voltage detection function, MAX/MIN and HOLD modes and a large LCD display.
The clamp allows you to measure AC current up to 400 A, AC/DC voltage up to 600 V and resistance up to 40 MΩ. Thanks to the maximum jaw opening of 28 mm, the device is convenient to use for checking individual conductors in electrical panels, electrical equipment and during diagnostics of electrical systems.
⚡ Current measurement up to 400 A without breaking the circuit
The UNI-T UT201+ current clamp allows you to measure alternating current without the need to disconnect the conductor and connect the measuring device in series. It is enough to cover one conductor with the jaws of the clamps and perform the measurement.
The ranges 4 A, 40 A and 400 A are provided for alternating current. This makes the clamp ammeter a convenient tool both for checking small loads and for measuring current in power electrical circuits within the characteristics of the device.
〰 True RMS — True RMS measurement
UNI-T UT201+ True RMS measures the true root mean square value of an alternating signal. The True RMS function is especially useful when working with electrical circuits where the waveform differs from a perfect sine wave.
This makes the UT201+ digital clamp meter suitable for diagnosing modern electrical and electronic equipment.
🔍 Non-contact NCV voltage detection
The built-in NCV function allows you to detect the presence of alternating voltage without contact. When detecting it, the UNI-T UT201+ uses sound and visual indication.
The non-contact voltage detector is convenient for preliminary checking of cables, sockets and electrical lines before performing basic measurements.
🔧 Voltage measurement, resistance and diode test
The UNI-T UT-201+ clamp multimeter is not limited to current measurement. Using the supplied probes, the device allows you to measure DC and AC voltage up to 600 V, as well as resistance up to 40 MΩ.
Additionally, there is a diode test and a function for checking the conductivity of the electrical circuit. Thus, the UT201+ can be used not only as a 400 A current clamp, but also for performing basic diagnostic measurements during repair and maintenance of electrical equipment.
📊 HOLD, MAX/MIN and automatic shutdown
The HOLD function allows you to fix the measurement result on the display. This is especially convenient when the device screen is difficult to see directly during measurement.
The MAX/MIN mode is used to control the maximum and minimum measured value. If the device is not used, after approximately 15 minutes the automatic shutdown is activated to save battery power. If necessary, this function can be disabled.
🔋 Energy-saving power supply
UNI-T UT201 Plus is powered by two AAA 1.5 V batteries. The device's current consumption is about 1.8 mA, and in sleep mode - less than 11 μA. The declared operating time from the battery pack can reach 400 hours.
For timely replacement of batteries, a low battery indication is provided.

🛠️ Where are UT201+ current clamps used
UNI-T UT 201+ current clamps are convenient for electricians, electrical repairmen, installers and radio amateurs. The device can be used to check the consumption of electrical devices, diagnose wiring, maintain electrical panels and find faults.
Thanks to the combination of the functions of current clamps and digital multimeter, the UNI-T UT201+ model allows you to measure alternating current up to 400 A, voltage up to 600 V, check resistance, diode or continuity of the electrical circuit with one device. The built-in NCV detector additionally helps to determine the presence of alternating voltage without direct contact.
⚠️ Please note
- The UT201+ current clamps measure AC alternating current; DC current measurement with DC clamps is not declared for this model.
- To correctly measure the current, the clamps must cover one conductor, and not the entire cable with phase and neutral wires at the same time.
- Before measuring, check the correctness of the selected mode and connection of the measuring probes.
- Do not exceed the maximum permissible voltage and current values for the device.
