A single motor in the frame of the tester actuates the drive of each sample stage through a drivetrain that is automatically engaged by the manual installation of the stage. Means for controlling and/or measuring temperature, humidity, voltage, resistance, and acoustic emissions are provided through dedicated expansion slots and cards that activate respective software. An electronic identification in each card ensures that only relevant software is enabled. | 10-15-2015 |
