The UNI-T UT-256B is an advanced and reliable digital meter that, thanks to its innovative open-jaw design, significantly facilitates the work of every electrician and electronics technician. This device is designed for fast and precise DC and AC current measurements up to 200A without the need to disconnect the circuit. Thanks to the True RMS converter, the user can be sure that the effective value readings are accurate even in the case of distorted waveforms, which is crucial in modern power installations.
The main advantage of the UT-256B model is its versatility. In addition to current measurement, the device offers full multimeter functionality, enabling DC voltage measurement up to 1000V and AC up to 750V, as well as resistance up to 60 MΩ and capacitance up to an impressive 60 mF. The NCV (Non-Contact Voltage) function allows for non-contact detection of voltage presence in wires, which drastically increases the level of safety during maintenance work.
The meter is characterized by a solid construction and an ergonomic shape that fits perfectly in the hand, and the built-in flashlight and backlit LCD screen enable work in low-light conditions. An additional advantage is the REL relative measurement mode, the HOLD function to freeze the result on the screen, and circuit continuity signaling. The device is powered by commonly available AA batteries, which, combined with the automatic shutdown function, ensures a long operating time. The set also includes a practical case that protects the meter from mechanical damage during transport. By choosing this model, you are investing in a professional diagnostic tool that combines laboratory precision with the durability of field equipment. It is an ideal solution for home appliance service technicians, photovoltaic system installers, and maintenance departments in industrial plants.

Software and Measurement Logic
The device's built-in microcontroller manages advanced measurement logic that analyzes input signals in real-time. The meter's operating system is responsible for implementing the True RMS algorithm, which precisely calculates the effective value of current and voltage waveforms, eliminating errors resulting from the presence of harmonics or wave distortions (e.g., in systems powered by inverters or frequency converters). The control logic manages automatic measurement range switching, selecting the optimal resolution for each measurement, which minimizes the time required for data reading. The device firmware also supports the NCV (Non-Contact Voltage) function, processing data from the electric field sensor into audible and visual signals. Additionally, the software monitors the power-saving system, automatically entering sleep mode after prolonged inactivity and monitoring the charge status of the power cells, signaling the need for replacement, which prevents erroneous readings at low battery voltage.
