The OTKBFM-CAL is used in combination with Thorlabs force measurement module OTKBFM. The following
installation procedure assumes that you have already completed the setup of the force module and that it is
working in combination with your optical tweezers setup.
1. Use the included CD/DVD to install the OTKBFM-CAL software on your PC or download the latest version
from the Thorlabs web page www.thorlabs.com/manuals. Make sure you are logged in with
administrative user rights for the installation.
2. The Thorlabs APT software should already have been installed on your PC during the installation of the
OTKBFM force module. If not, please download the APT software from our web page and install it.
3. Use the SMA-to-BNC cables (included) to connect the OTKBFM-CAL to the K-Cube piezo and strain
gauge controllers. See Figure 3 below for details.
4. Connect the OTKBFM-CAL module via the USB cable to the PC and connect the power supply to the
OTKBFM-CAL module. Ensure that the power supply is set to the correct voltage level for your region and
