Description
Functions
- Data produced by the instrument:
a. TR test: TR10. TR30. TR50. TR70. TRx1, TRx2 (x1, x2 customer defined)
b. Time from test start at calculated TR points - Graphic representation:
a. Retraction percentage versus Temperature Curves for the 6 samples tested.
b. Temperature versus Time curve during test. - Automatic performance of the test with adjustment of the thermal cycle and automatic release of the samples on termination of the conditioning time depending on the test procedures used.
- Graphic representation of Retraction curves for each of the 6 samples and of Test Bath temperature during test.
- Possibility of testing groups of different samples with different percentage elongation during the same test.
- Calculation of the significant test results for each sample.
- Calculation of average and standard deviation for each group of samples tested.
- Setting of tolerance limits for conditioning temperature to verify correct pre-start conditioning
