Attach the accelerometer to the DUT.\n\n - Use beeswax to attach the accelerometer at the location specified in the\n test app.\n\n - The accelerometer connection should be rigid but also easy to remove\n between runs.\n\n2. Set the orientation of the accelerometer depending on the actuator type.\n\n - **X axis linear resonant actuator (LRA):** Make sure that the -\\\u003e on the\n accelerometer is aligned with the length direction of the LRA. This\n direction is generally equivalent to the resonating direction.\n\n - **Z axis linear resonant actuator (LRA):** Use the accelerometer\n orientation described in the X axis LRA instructions above.\n\n - **Eccentric rotating mass actuator (ERM):** Measure the signal and all\n three axes, then select the data that has the strongest signal amplitude.\n\n | **Note:** If you change the measuring axis, be sure to also change the accelerometer cable attached to the CCLD signal conditioner.\n3. Open the test app on the DUT and generate target effects.\n\n - Use a Bluetooth mouse to click the target buttons in the app. This lets\n you click app buttons without adding external forces, such as pressure from\n a finger.\n\n **Figure 1.** DUT generating target effects\n4. Record the waveform from the test app using Audacity and export the file:\n\n - Click **Record** in Audacity.\n - Press each of the target buttons in the test app.\n - Export the recording as a WAV file.\n\n **Figure 2.** Exporting from Audacity"]]
