+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 motion trial for the report mode 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.
+==== Static Trials ====
-  - 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]] 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. ideally there should be 8 or more, with at least one near each corner of the force platform and one near the center of the force platform.
-  * each example motion trial that is downloaded with the caltesterplus program meets these criteria.

-====== compute platform pose ======
+  * Each example motion trial that is downloaded with the CalTesterPlus program meets these criteria.
-computing the platform pose gives you a written report of the force platform's optimal location in your lab. this report can be saved as a text file and the values can be inputted into the data collection software that you use. you can either complete this tutorial using data you have collected in your own lab following the guide lines above, or by using the sample data that was provided when you installed caltesterplus. this sample data can be found on the following file path: c:\program files\c-motion\caltesterplus\samples\tutorialfiles
+===== Compute Platform Pose =====
-**1. use the add button at the top right-hand side of the screen to load all of the .c3d files that you want to use to create a report from, and select them by highlighting them. for the sample data we will be using the files "trialback1.c3d" through to "trialback11.c3d".**

-**2. make sure that you are on the platform tab at the bottom section of the screen.**\\
-(a) check that you have selected the force platform number that corresponds to the force platform that the caltester rod was used on. if you are using the sample data it is fp 1.\\
-(b) check the use specified platform dimensions if you have inputted the force platform sizes into the fp size tab. if the force plate size has been specified before, select the desired fp, if not, please select the desired plate before completing step 6 of this tutorial.\\
-(c) check that the minimum valid force is set to 100 n.\\
-(d) do not check "update selected template instead of updating corners", this option indicates that the user would like to create a jig template which is explained [[caltester:caltesterplus:tutorials:jig_location|here]].\\
