Description of Self Test Items C-7
Test Content
The Doppler reads the brightness according to the brightness sensor on the main monitor. It can
adjust the brightness degree. It is designed to test whether the brightness sensor can work. (Note:
the self-test does not set the brightness for the monitor. Set the brightness via “Primary monitor
control test” and “Secondary monitor control test”).
Adjust the light sensor of the primary monitor to light spot in bright circumstance. Do not perform
the test in dark circumstances. The test program reads the circumstance light and shows it on
the monitor. Block the light sensor with the hand. View whether the circumstance light changes or
not (the test value can reach 50 if the light circumstance is well.)
Analysis to Test Failure
The drive goes wrong if the test result appears Error.
Suggestion to Test Failure
If the circumstance light value is low, check whether the light sensor on the monitor is block or not.
b) If the circumstance light keeps the same value, it is recommended to change the connection
cable of the sensor light.
C.1.16 Z0501 Secondary LCD Monitor I2C Interconnection
Test
Top test item
PC Module and MF FPGA Interconnection Test
Test content
Test whether I2C communication serial port between MF FPGA and secondary LCD works well.
The test generates secondary LCD’s saver, and then returns back. Secondary LCD’s brightness
decreases, and then returns back. Read the hardware and software versions of secondary LCD.
Analysis to test failure
The drive goes wrong if the test result appears Error.
The interconnection between MF FPGA and secondary LCD goes wrong if the test result is FAIL.
Suggestion to failure test
Restart the device to perform the self test if the test result appears Error. It is necessary to restore
the device (OS+doppler) if Error re-appears.
Check whether the connecting material between secondary LCD and main unit is fixed well, and
then replace main monitor if the test result is FAIL.
