Specification for the software

Specially designed for tensile under load/stress control and crosshead separation control (by using the displacement transducer supplied with the machine), allowing:
-Simultaneous display of stress/time, stress/elongation                           %,
elongation/time and stress/elongation;
-possibility to overlap two elongation/stress graphs: one obtained with the included displacement transducer measuring crosshead separation travel and the other obtained with an optional extensometer (coaxial or universal);
-Elaboration of tension test results : ReH, ReL or Rp (calculated at three different elongation percentages selectable by the ser), A,Ag,At,Agt,Ae,Rt,Z, Elastic modulus E, etc, conforming to EN ISO  6892-1  and  EN  15630-1  for
steel rebars.
