Pc-Check Windows Accelerometer Acceleration Test Failure Information

Group Number 120X

Device Accelerometer

An accelerometer is a device that measures linear acceleration of movement and is often used to detect if the system is dropped, picked up or interacted with using motions."

Some smart-phones and tablets contain accelerometers for user interface control. Often the accelerometer is used in conjunction with a gyroscope to present landscape or portrait views of the device's screen, based on the way the device is being held.

Test Number 303

Acceleration

The acceleration test checks the measurements of acceleration in three directions. The interactive test requests moves the system from left to right, right to left, up-down, down-up, forward-reverse and reverse-forward direction. The test succeeds once the detected acceleration in each axis exceeds 20% as default of the sensors capable acceleration range.

Estimated Test Time Depends on the time-out parameter set by the user.

PARAM_ID1: Time-out

Test time-out parameter whilst awaiting user interaction in seconds.

PARAM_ID3: Sample Size

Accelerometer Number of samples for noise testing.

PARAM_ID4:Cluster Size

Accelerometer size of average cluster, smaller it, better it will be able to pick measurement inaccuracies.

ERRORCODES & TROUBLESHOOTING

The sensor was not found. CODE=0x00/3FF

TROUBLESHOOTING0: The sensor was not detected. This could be caused by faulty drivers or a loose connection.

The sensor failed to start. CODE=0x01/3FF

TROUBLESHOOTING0: The sensor was not detected. This could be caused by faulty drivers or a loose connection.

Access to the sensor was denied. CODE=0x02/3FF

TROUBLESHOOTING0: The sensor was not detected. This could be caused by faulty drivers or a loose connection.

The sensor has encountered an error. CODE=0x03/3FF

TROUBLESHOOTING0: The sensor was not detected. This could be caused by faulty drivers or a loose connection.

The sensor is in an unknown state. CODE=0x04/097

TROUBLESHOOTING0: The sensor was not detected. This could be caused by faulty drivers or a loose connection.

Unable to create an interactive test window. CODE=0x05/001

TROUBLESHOOTING1: Creation of the interactive window failed or the test timed out. Most likely an operating system error.

The test timed out whilst awaiting user interaction. CODE=0x06/3FF

TROUBLESHOOTING1: Creation of the interactive window failed or the test timed out. Most likely an operating system error.

The Operator chose to fail the test. CODE=0x07/3FF

TROUBLESHOOTING2: The interactive test failed since the operator cancelled the test. More information on failure should be requested from the user.

Required files to perform the test are missing from the diagnostic directory. CODE=0x08/3FF

TROUBLESHOOTING3: Required files to perform the test are missing from the diagnostic directory. Check the deliverable to ensure no files are missing or deleted.

Error attempting to read minimum and maximum range. CODE=0x09/3FF

TROUBLESHOOTING4:In order to perform some tests the minimum and maximum range of acceleration in G must be supported. This device does not have that capability.

Error attempting to control screen rotation. CODE=0x0A/3FF

TROUBLESHOOTING5:Screen rotation must be disabled to control tests otherwise this will effect. Most likely an operating system issue.

Noise above the threshold for the sensor CODE=0x0B/3FF

TROUBLESHOOTING4:In order to perform some tests the minimum and maximum range of acceleration in G must be supported. This device does not have that capability.
