CASSY App vs AccelVisu2

With the CASSY App, students and teachers can measure, observe and analyse using CASSY – on an iPad or iPhone. It’s simple and practical for everyday use: just type in the PIN from the CASSY display or scan the QR code and start measuring straight away. - Free experimentation without fixed experimental parameters - Group measurements: connect up to 4 devices to a single CASSY simultaneously - Live measurement results on an external display in digital and analogue displays, tables and diagrams - Free configuration of measurements - Comparison of multiple measurements - Individual evaluation per student - Save results and load measured values for analysis - Exam mode for exam security (configurable via CASSY teaching profiles on our LeyLab online portal) - Can be used without internet access The CASSY App supports all CASSY sensors and the following CASSY devices: - Mobile-CASSY 2 WiFi (524 005W2, 524 005W) - Power Analyser CASSY (727 101, 727 111) - Machine Test CASSY (773 1901, 773 2901) - Converter Controller CASSY (773 5291) - Power Control CASSY (773 530) You can obtain a compatible CASSY and the sensors from LD DIDACTIC GmbH.

With this program, the values ​​of the built-in accelerometer are read and displayed live as the acceleration vector. After starting the App it shows a coordinate system in which the XY projection of the measured acceleration is shown as an arrow. In addition, the X and Y components of the acceleration measured in the direction of the two axes is displayed as each line (green and red). The display of the instantaneous acceleration value of all components is in m / s above the coordinate system. By pressing the "Record" button, you can record the acceleration values. ​To display the recording click on the button "Play". By clicking on "Export", you can send the data with an email to you. In the bottom bar can be reached via the "Settings" on the configuration options. There, the measurement frequency, recording time and the softness for suppressing tremors can be adjusted. Similarly, can be switched off via a slide switch of the influence of gravity.
