Description
UNI-T UT256A Multimeter
This product comes with a 3-year warranty. The UT256A digital multimeter is a safe and reliable clamp-on meter that can replace a clamp-on multimeter. It has no moving mechanical parts, making it resistant to mechanical failure. The device has a display with a maximum reading of 6000. The use of a Hall-effect probe allows AC current to be measured up to 200A. Using the included test leads, AC and DC voltage, resistance and wire continuity can also be measured; it features a built-in non-contact AC voltage (NCV) sensor and a built-in lamp. It features data hold, automatic and manual range selection, a backlit display, frequency measurement and a low battery indicator. The maximum wire diameter that can be inserted into the clamp is 15 mm. Range overrun is indicated by a red LED, and for NCV by an audible signal. A key advantage is its resistance to drops from a height of up to 2 m. Powered by two 1.5 V AA batteries. These features make the UT256A multimeter a practical tool for the daily work of high-voltage electricians.

- overload protection at 1000 Vrms
- open-circuit voltage approx. 1 V
- Circuit continuity check:
- if the measured resistance is less than 10 Ω, the continuity circuit signal emits a buzzer
- if the measured resistance is greater than 100 Ω, the open-circuit signal does not sound a buzzer
- open-circuit voltage of approximately 1/060 V

- Overload protection at 1000 Vrms
- Non-contact electric field sensing (NCV):
- low voltage detection mode ("EFLo") for voltages <48V
- low voltage detection mode ("EFHi") for voltages >-48V: as the voltage increases, the number of segments on the display increases, the green, yellow and red LEDs flash in succession and an audible signal is emitted
