∙
When the distance between this amplifier and the bridge circuit for the strain measurement is
long, the cable length compensation function to correct the voltage drop of the excitation from
DSA-631 is equipped as a standard.
∙
As for this function, the transducers and the bridge box is required to be composed of the
Wheatstone bridge circuit.
∙
There is a model that has inserted the resistor for the output conditioning of the transducer
internally. In applying such a transducer, the excitation to the transducer rises more than
usually (Up to 130 % or less) to consider that the resistance is caused by the cable length and to
compensate the voltage drop. Therefore, as a rule, please turn off the cable length compensation
function when transducer is used.
