Instron Load Frame / Microscope Repair

The computer interfaced with the Nikon Fluorescent microscope camera in Castleman room 214 had a forgotten admin password and was inaccessible. Being an old computer, it was decided to upgrade the current (inaccessible) computer and swap the PCI card into the new one. This afternoon I made the swap and installed the appropriate drivers and software on the computer. Initial testing of the camera (Spot RT) working with the software seemed good, but I will wait for help before turning on the microscope for testing.
The computer and microscope shown to the left is the system we will be using. Eventually we will need to use the image-capture capabilities of the camera system.
Earlier this morning was supposed to be our final day of Intron training for the load frame and FastTrak 8800. After beginning the training we ran into trouble as the software was showing a low-power warning for testing systems. This quickly devolved into a troubleshooting session lasting over two hours. We first discovered our second card in the FastTrak system was not linked to the primary card, this may have been causing issues. But secondly, the number 2 SEM chip on card 2 was malfunctioning and reporting a load cell connected to it, when in fact nothing was connected to it. Our Instron representative will return within a week or two to replace the SEM card and resolve our mysterious load cell low power issue. [I think I'm going to call it an LC undervolt]. We will also have to reschedule our Console training to learn how to set operation limits for the load arm and set the PID for different testing materials.
