7 Failure reasons and troubleshooting
1) Under normal operation, TF03 sometimes will output 0 values.
Reasons: In order to better identify the data validity of TF03, the 0 values are
specifically used as abnormal state values. TF03 will output a distance value of 0,
generally in two cases: first, the actual distance measured is within the blind zone
of TF03; and second, the actual distance measured is beyond the range of TF03.
For example, when measuring the distance to a wall, TF03 is 5cm away from the
wall but its blind zone is 10cm. As TF03 is unable to measure any valid data, it may
output the value 0.
Troubleshooting: Use the value 0 as a value representing abnormal data. In other
words, after the value 0 is received, the TF03 output data is not used, but when a
non-zero value is received, the TF03 output data will be used.
2) No data output after TF03 is connected.
Reasons: Any product before delivery will undergo strict inspection, so as to
ensure that it can be used normally. Therefore, product defects may have arisen
during transportation or use.
Troubleshooting: Check whether the power supply is working properly, and
whether the voltage level is kept within the range of the rated input voltage. If the
power supply is normal, the TF03 lens will display a faint red light.
Check whether data parsing is correct. Parse the data in accordance with the data
frame format as described above.
If the problem remains unsolved, contact the technical support team
([e-mail]). We will try our best to solve your problems.
3) No data output after TF03 is connected to the TF display software.
Reason 1: The computer uses an operating system other than Windows.
Troubleshooting: Currently, the TF display software can only support the Windows
operating system. Use a computer with the Windows operating system installed.
Reason 2: Poor connection between TF03 and computer.
Troubleshooting: Please confirm that TF03 is correctly and reliably connected to
the computer, and ensure that the cables and adapter board work properly.
