To start the\ntests, in CTS-V, click **Barometer measurement tests**. The following tests\nappear one by one.\n| **Note:** You're required to complete all tests sequentially. If any test fails, you can retry the test it until it passes, or continue the test sequence with a failed result.\n\n### Run test1SqueezingImpact\n\nThe squeezing impact test ensures that the barometer isn't impacted when a user\nsqueezes the device. To run the squeezing impact test:\n\n1. Hold the device in your hand steadily.\n2. When prompted, squeeze the device quickly then release. CTS-V identifies if the barometer is impacted.\n\nIf the barometer is impacted, the test fails. You can choose to retry or\ncontinue to the next test. Otherwise, the test succeeds and you can proceed to\nthe next test.\n\n### Run test2TappingImpact\n\nThe tapping impact test ensures that the barometer isn't impacted when a user\ntaps the screen. To run the tapping impact test:\n\n1. Place the device on a food scale.\n2. When prompted, tap the spots on the screen then lift off quickly. Your taps need to be strong enough to register 500 g on the scale. CTS-V identifies if the barometer is impacted.\n\nIf the barometer is impacted, the test fails. You can choose to retry or\ncontinue to the next test. Otherwise, the test succeeds and you can proceed to\nthe next test.\n\n### Run test3FlashlightImpact\n\nThe flashlight impact test ensures that the barometer isn't impacted when the\ndevice is exposed to flashlight. To run the flash light impact test:\n\n1. Hold the device steadily.\n2. When prompted, shine a flashlight on each side of the device for the duration indicated in CTS-V. CTS-V identifies if the barometer is impacted.\n\nIf the barometer is impacted, the test fails. You can choose to retry or\ncontinue to the next test. Otherwise, the test succeeds and you can proceed to\nthe next test.\n\n### Run est4RadioImpact\n\nThe radio impact test ensures that the barometer isn't impacted when the device\nis exposed to radio frequencies. To run the radio impact test:\n\n1. Place the device on a flat surface.\n2. This test begins with the radio turned off (including Bluetooth, Wi-Fi, mobile data) to collect baseline data.\n3. When prompted, turn off airplane mode and turn on all radios.\n4. When prompted, turn off the radio and turn airplane mode on. CTS-V identifies if the barometer is impacted.\n\nIf the barometer is impacted, the test fails. You can choose to retry or\ncontinue to the next test. Otherwise, the test succeeds and you can proceed to\nthe next test.\n\n### Run test5WalkingImpact\n\nThe walking impact test ensures that the barometer isn't impacted when the user\nwalks with the device. To run the walking impact test:\n\n1. Hold the device steadily in your hand with the screen facing up.\n2. When prompted, walk with the device for the duration indicated in CTS-V. CTS-V identifies if the barometer is impacted.\n\nIf the barometer is impacted, the test fails. You can choose to retry or\ncontinue to the next test. Otherwise, the test succeeds and you can proceed to\nthe next test.\n\n### Run test6SmoothingWithinSameActiviation\n\nThe smoothing within same activation test ensures that the smoothing within the\nsame sensor activation meets the requirements. To run the smoothing within same\nactivation test:\n\n1. When prompted, hold the device at different heights during the test.\n2. Make sure the device is always parallel to the ground with the screen facing up. CTS-V identifies if the smoothing meets the requirements.\n\nIf the requirements aren't met, the test fails. You can choose to retry or\ncontinue to the next test. Otherwise, the test succeeds and you can proceed to\nthe next test.\n\n### Run test7SmoothingacrossActivations\n\nThe smoothing across activations test ensures that the smoothing across sensor\nactivations meets the requirements. To run the smoothing across activations\ntest:\n\n1. Ensure you're on a floor of a building that has at least two accessible floors below you.\n2. Find an appropriate location prior to starting the test where you can lift the device to 2 m above the floor where you start the test.\n3. When prompted, move to two floors below the floor where you started the test. CTS-V identifies if the smoothing meets the requirements.\n\nIf the requirements aren't met, the test fails. You can choose to retry or\ncontinue to the next test. Otherwise, the test succeeds and you can proceed to\nthe next test.\n\n### Run test8TemperatureCompensation\n\nThe temperature compensation test ensures that barometer is temperature\ncompensated. To run the temperature compensation test:\n\n1. Put the DUT in the fridge.\n2. After 20 minutes, CTS-V chimes to prompt you to remove the DUT.\n3. Take out the DUT, and put it and the reference device side by side on a flat surface.\n4. When prompted, set the date and time to be the same for both devices.\n5. When prompted, enable Bluetooth on both devices.\n6. When prompted, open the CTS-V app on the reference device, and click **Barometer reference**. You should see a list of Bluetooth devices near you.\n7. On the DUT, click **Next**. The Bluetooth pairing screen opens.\n8. On the reference device's list, find the DUT. If not found, click **Scan for devices**. The pairing prompt appears after 10 seconds.\n9. On both devices, click **Pair**. The devices are paired.\n10. Click **Next**. CTS-V identifies if the barometer is temperature compensated.\n\nIf the requirements aren't met, the test fails. You can choose to retry\nor continue to the next test. Otherwise, the test succeeds and you can proceed\nto the next test."]]
