-|In order to use the CalTesterPlus program you need a set of properly collected data for each force platform you wish to calibrate. To collect a useful static trial for CalTester follow the following process.\\ \\ - Set up your capture volume making sure that all force platforms and cameras are in the positions that they will remain in for following data collections.\\ - Place the [[CalTester:CalTesterPlus:Hardware#Base_Plate|CalTester base plate]] on the force platform before you begining the collecting the trial.\\ - Zero the force platform so that it will not record the force produced by the CalTester base.\\ - Begin the trial with the [[CalTester:CalTesterPlus:Hardware#Rod_and_Markers|CalTester Rod]] on the CalTester base plate OFF the force platform.\\ - Press down firmly on the Rod with a load of at least 200 N.\\ - Keep the Rod aligned vertically and motionless during the trial.\\ - The trial needs to be at least 1 second long.\\ - There should be a minimum of three trial collected per force platform.
