    The principle of the video extensometer is based upon accurate detection of the gauge length markers using a high resolution digital video camera. There are two models of the second generation Instron video extensometer; the AVE2 (Advanced Video Extensometer) and the SVE2 (Standard Video Extensometer).

  • Page 14: Averedge32™ Option (Ave2 Only)

    Chapter: Introduction Figure 1. AVE2 AverEdge32™ option (AVE2 only) The AverEdge32™ option, available for the AVE2, is an advanced capability available in ® Bluehill Universal software for measuring strain using the edges of the specimen instead of dots placed on the specimen. It requires a different mounting system that includes a back screen.
