To calibrate the fuel level on your FOXTECH product, please follow these steps:
1. Connect to the TTL serial port: Use a TTL serial cable to connect your device to the computer. Open the software and click on "Serial Port Resources" and then "Refresh" to detect the serial port (e.g., COM3). Select the detected serial port.
2. Open the serial port: Click on "Open Serial Port" button. The left light above the button should turn on and the right light should start blinking, indicating a successful connection.
3. Servo calibration: Click on "Calibration Readout" to set the throttle valve position to 0%. This will set the current position as the zero position of the throttle valve. Adjust the bottom dead center (BDC) of the servo while the throttle valve is at 0%. Click on "Hold" and change to "Adjust". Then click on "Calibration Write In" to modify the calibration.
4. Set throttle valve to 100%: Set the throttle valve position to 100% and adjust the top dead center of the servo. Click on "Hold" and change to "Adjust". Then click on "Calibration Write In" to modify the calibration.
5. Verify calibration: Adjust the throttle valve position to the top or bottom dead center. If there is no current sound from the servo, you can reconnect the power and pull the "Set Throttle Valve Position" to check if the writing is successful.
6. Oil level calibration: Click on "Calibration Readout" to read the currently set calibration data. Place the sensor into the fuel tank and the oil level will automatically change. Based on the current oil level, write the added oil amount. Click on "Hold" and change to "Adjust". Then click on "Calibration Write In" to modify the calibration. Note that only one data can be written at a time.
7. Modify the number of valid items: Modify the "Number of valid items in the sample" by writing the total number of calibration items. The number of effective items is the effective number from the first item.
Caution:
- Make sure to open the serial port first before adjusting the servo and oil level.
- If the left light is on and the right light is blinking unevenly and slowly, the connection has failed. Exit the software and try connecting again.
- When calibrating the servo, the minimum value corresponds to the bottom dead center and the maximum value corresponds to the top dead center.
- During oil level calibration, only one value can be written at a time. You can read the calibration data to observe if the writing is successful.
