UNI-T UT256A Digitale stroomtang

The UT256A digital multimeter is a safe and reliable fork meter that can replace a clamp multimeter. It has no mechanically moving parts and this results in its resistance to mechanical failures. The device has a display with a maximum display value of 6000. Using a fork with a Hall probe allows the measurement of AC current up to 200A. Using the included measuring cables, it is also possible to measure AC and DC voltage, resistance, wire continuity, it has a built-in non-contact AC voltage sensor (NCV) and a built-in lamp. It has data pause functions, automatic and manual range selection, backlit display, frequency measurement, low battery indication. The maximum diameter of the wire that can be inserted into the fork is 15mm. Indication of range exceeding by red LED, for NCV by acoustic signal. The advantage is 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 device for the daily work of high-voltage electricians.
