Dimension Application Module Installation

  1. Remove the Dimension head.
  2. Place the application module sensor flush on the flat part of the piezo guard, and tighten it down using the two #2-56 screws. Be careful not to overtighten (see Figure 1).
NOTE: The allen head screws and a matching allen wrench are included in the application module kit.

  1. Install the Dimension head on the dovetail mount by completing the following (see Figure 2):
    1. Release the clamping screw by turning it counter-clockwise until the head is secure.
    2. Plug the head 21-pin connector and the application module 15-pin connector into the receptacles on the front of the microscope.

  1. When installing the Dimension head, carefully check the clearance between the sample/stage and the tip/scanner to prevent the tip/scanner from crashing into the sample/stage. If it appears that the tip/scanner may crash when fully inserted, remove the Dimension head completely and execute the Motor > Withdraw command. You may also select Stage > Focus Surface and use the trackball to obtain sufficient clearance and avoid a crash
NOTE: It is very important to release the clamping screw on the dovetail, and ensure the Dimension head is tightly secured in the mount. A loose Dimension head causes a large increase in image noise due to reduced rigidity of the mechanical support of the SPM head.
  1. Install a probe in the appropriate Dimension probe holder (see Figure 3 in Dimension Hardware Description); for SCM, C-AFM, SSRM and TUNA, refer to your Dimension instruction manual for guidance.
  2. Insert one end of the Universal Connector into the central single-wire socket of the application module you are installing (see Figure 3 in Dimension Hardware Description). Each application module has an unique location to attach the Universal Connector (see Figure 3).
