6. Speed Ratio Setting

The tachometer requires a speed ratio setting to accurately display RPM based on your engine's cylinder count or outboard poles. This setting is crucial for correct operation.

1. ເຂົ້າສູ່ໂໝດການຕັ້ງຄ່າ: Press and hold the rubber button on the backside of the gauge for more than 3 seconds. The gauge will enter setting mode. If no action is taken for 3 seconds, it will exit setting mode.
2. ປັບຄ່າ: While in setting mode, each short press of the button will increase the speed ratio value. Press and hold the button to decrease the value. The minimum step value is 0.1, and the adjustable range is 1.0-360.
3. ບັນທຶກການຕັ້ງຄ່າ: Once the desired speed ratio value is displayed, release the button. The tachometer will automatically save your setting after 3 seconds. If the setup is not satisfactory, repeat the process.

Speed Ratio Reference Table:

Use the following table as a general reference. Note that this table provides common values; actual requirements may vary. If your engine cylinder number is not listed or you require further assistance, please contact customer support for a suitable speed ratio value.

7. ການດໍາເນີນງານ

7.1 RPM Display

Once correctly installed and configured with the appropriate speed ratio, the gauge will display the engine's rotational speed in RPM (Revolutions Per Minute) via the needle. The scale ranges from 0 to 6000 RPM.

7.2 ຊົ່ວ​ໂມງ

The integrated digital display at the bottom of the gauge functions as an hour meter, recording the total operating time of the engine. This value is stored even when power is off. The hour meter range is 0-99999.9 hours.

9. ການແກ້ໄຂບັນຫາ

• Gauge Not Powering On:
  • Check the red wire connection to the 9-32VDC power supply.
  • Verify the black wire connection to ground.
  • Ensure the power source is active and within the specified voltage ຊ່ວງ.
• RPM Reading Incorrect or Stuck:
  • Re-check the blue wire connection to the RPM signal input. Ensure it is securely connected and receiving a signal.
  • Verify the speed ratio setting (refer to Section 6). An incorrect speed ratio is a common cause for inaccurate RPM readings. Adjust the speed ratio according to your engine's cylinder count or outboard poles.
  • If the gauge is stuck at maximum RPM, it often indicates an incorrect speed ratio setting or an issue with the signal input. Try adjusting the speed ratio.
• Backlight ບໍ່ເຮັດວຽກ:
  • Check the yellow wire connection to the backlight power supply.
  • Ensure the color change button on the backside of the gauge is functioning.
• Hour Meter Not Recording:
  • The hour meter operates when the gauge is powered. If the gauge is on but the hour meter is not advancing, ensure the RPM signal is being received correctly.

10. ບໍາລຸງຮັກສາ

The MAIMEIMI Tachometer Gauge is designed for durability and requires minimal maintenance. Follow these guidelines to ensure its longevity:
