3.1

 

Performance features 

The 7KT1681 and 7KT1682 multimeters are designed such that they combine maximum 

operating comfort with a wide range of advanced functions, and this despite the extremely 

restricted dimensions of the modular enclosure (only 4U). 
The backlit LCD offers intuitive operation of the clearly laid out user interface. 
The 7KT1682 additionally features an insulated RS 485 communications interface with 

Modbus protocol support.
