Abstract
Four-terminal-pair devices which must be operated at liquid helium temperatures can only be connected to the measurement setup with relatively long thin cables. This unfortunately leads to a large increase of the errors introduced by these cables. Some considerations are presented which allow these errors to be reduced as is necessary for precision measurements.<>
