Stroboscope app and optical tachometer for measuring rotating, vibrating, oscillating or reciprocating objects. Optical tachometer can be used by starting it from MENU - TACHOMETER. It is most commonly used for: - adjusting speed of rotation - for example adjusting speed of rotation of turntable - adjusting frequency of vibration How to use: 1. Start app 2. Set frequency of strobe light (in Hz) using number pickers 3. Press ON/OFF button to start the strobe light - use button [x2] to double the frequency - use button [1/2] to halve the frequency - use button [50 Hz] to set frequency to 50 Hz. This is for turntable speed adjustment. - use button [60 Hz] to set frequency to 60 Hz. This is also for turntable adjustment. - activate duty cycle by checking [DUTY CYCLE] check box and adjust duty cycle in percentage. Duty cycle is the percentage of time per cycle when the flash light is on. - optionally you can calibrate the app by starting calibration from MENU - Calibrate. It is good to do calibration when frequency is changed. You can also set correction time manually in Settings. Accuracy of the stroboscope depends on latency of your device flash light. Optical tachometer can be used by starting it from MENU - TACHOMETER. It analyzes moving objects and determines frequency in Hz and RPM. How to use: - point the camera to the object and press START - hold steady for 5 seconds - result is shown in Hz and RPM You can save images captured during measurement by clicking on disk icon. At the end of measurement a message will be shown with information how many images were saved. Images are saved in folder Pictures/Stroboscope. The name of the images ends with information how many milliseconds they were taken relative to first picture. You can use this information to determine the object RPM by calculating time between similar images. Minimum and maximum frequency can be set in SETTINGS - TACHOMETER. Increasing minimum frequency will reduce time needed for measurement. Maximum frequency is 30Hz (1800 RPM). Reducing maximum frequency will improve time needed for processing during measurement.
