able extension
For extending cables, only use shielded low capacity measurement cables
(measurement cables provided by
HBM
1)
meet these requirements). Ensure
that there is a perfect connection with the lowest possible transition
resistance. If you use the 6wire circuit, you may neglect any interference by a
change in the resistance of the extension cables. However, if you extend the
cable using the 4wire technique, the characteristic value deviation can be
removed by adjustment. Temperature influences will not be compensated.
