Multimeter UNI-T UT256A

Product detailed description

Multimeter UNI-T UT256A
We offer a 3-year warranty on this product. The UT256A digital multimeter is a safe and reliable fork-type meter that can replace a clamp-on multimeter. It has no mechanically moving parts and hence its resistance to mechanical failure. The instrument has a display with a maximum display value of 6000. By means of a Hall probe fork, it allows AC current measurements up to 200A. It can further measure AC and DC voltages, resistance, conductor continuity using the included measurement cables, has a built-in non-contact voltage (NCV) sensor and a built-in light fixture. It has data suspend functions, automatic and manual range selection, backlit display, frequency measurement, low battery indication. The maximum wire diameter that can be inserted into the fork is 15mm. Indication of exceeding ranges by red LED, for NCV by acoustic signal. The advantage is the resistance to falling from a height of up to 2m. Powered by two 1.5 V AA batteries. These features make the UT256A multimeter a practical instrument for the everyday work of power electricians.

- Checking the continuity of circuits :
- when the measured resistance is less than 10 Ω, a continuous circuit is signaled and a buzzer sounds
- when the measured resistance is greater than 100 Ω, the disconnected circuit indication does not sound the buzzer
- open circuit voltage about 1.0 V
- measurement on 600 Ω range, with 0.1Ω resolution
- 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 detected voltage increases, the number of segments on the display increases, the green, yellow and red LEDs flash sequentially and a buzzer sounds
