The AE extensometers are controlled through our Horizon software via a serial interface (RS 232 or USB). All movements can be initiated at any time required. The measuring arms
can be positioned parallelly within the available interval under computer control and thus can quickly be adjusted symmetrically to different sample lengths. The gauge length (L0) can
be set from 10 mm to the maximum possible measuring stroke. The travel is simply calculated from the maximum measurement range of 300 mm (or 500 mm for the AE500) less the gauge length.
The AE models have an additional positioning range of 190 mm for the symmetrical adjustment of the initial gage length. With the arms open the required measurement position can
be approached. Before the approach of the measuring position the digital measurement system is calibrated by reference marks. The opening and closing of the arms can be initiated at
any time required.
