1. WARNING Many degreasing and cleaning solvents are flammable and must be kept away from open flames and sparks Use only under well ventilated conditions Do not smoke while using flammable solvents CAUTION Ensure that any cleaning solvent does not contact the USB receptacle Liquids especially cleaning compounds have the ability to electrically damage the Slam Stick X device After applying the double sided tape to the underside of the Slam Stick X the device may be mounted to the intended surface for data logging Be sure that the mounting surface is also clean and devoid of any dust and small particles After the area has been cleaned and is dry the Slam Stick X can be mounted A few pounds of force should be exerted on the Slam Stick X by hand to compress the tape and better fix the device in place CAUTION The Slam Stick X has a plastic enclosure therefore the user should not overstrain the device when mounting it to a surface or use a metal blade to clean the surface Be sure to note the mounting orientation of the Slam Stick X Mid recommends taking a photograph after mounting the device so that the orientation can be verified after data logging The membrane on the outside of the device includes a coordinate system reference which is further explained in Figure 5 If the device is being mounted in an environment with a preexisting coordinate system such as an aircraft be sure to align the device s coordinate system with that2. 1N u EXE 177482 sernoles imported OLEI 356200295 Y 10 1139 X UTC 2014 07 28 21 59 30 0027 177492 samples imported Buffer Minimum Figure 16 The buffer minimum and maximum lines display how the maximum and minimum acceleration levels are changing with time When there are more buffers than the number of pixels on the screen the Slam Stick Lab plots just the buffer maximum and minimums as shown in Figure 17 This is done to enable faster drawing times and to provide a clear visualization on the acceleration data extremes The data used to generate the shown plot was generated from a frequency sweep when sampling at 10 kHz The sweep is very similar to the one shown in Figure 16 but for that plot the device was only sampling at 1 kHz SLAM STICK X Version No 1 0 Section Slam Stick Lab Software Overview 28 Figure 17 When there are more buffers then pixels on the screen the Lab will plot all the buffer max and minimums instead of data points for optimization purposes Recording Properties Once a recording has been loaded Slam Stick Lab can display information on the recording file and on the device that generated the recording To access this information click on Recording Properties under the File drop down menu or use the keyboard shortcut Ctrl I as shown in Figure 18 pem File Edit View Device Data Help New Viewer Window Close Viewer Window Open Stop Importi
