HIOKI 3256-50 | Hi Tester
The 3256 and 3257 models bear the CE mark meaning that they conform to standards such as the IEC61010-1 international safety standard and other EMC-related standards. Moreover, these units are designed with an emphasis on safety. In addition to a shutter mechanism that prevents incorrect test lead connection, the current terminals of the units come equipped with standard fast blow fuses.
In the AC V range, the 3256 can be used to check whether power lines are live. When the sensitivity level is set to 4 and the test head is placed near a live power line, the built-in buzzer sounds and a display indicator lights.
