3.2 Components
The EBTOOLS Digital Water Level Gauge kit typically includes:
- 1 x Water Level Gauge (J-YK00030)
- 1 x Instruction Manual
4. Setup and Installation
4.1 Mounting the Gauge
- Choose a suitable location on your dashboard or control panel that allows for clear visibility and does not obstruct operation.
- Drill a mounting hole with a diameter of approximately 52mm (2.0 inches). Ensure the hole is clean and free of burrs.
- Insert the gauge into the drilled hole. Secure it from the back using the provided mounting bracket and nuts.

4.2 Wiring Connections
Refer to the wiring diagram (if provided with your product) and the back of the gauge for terminal identification. Ensure all connections are firm and correctly polarized.
- Power Supply: Connect the positive (+) terminal to a switched 12V/24V DC power source and the negative (-) terminal to a reliable ground. The gauge supports 9-32V DC.
- Sensor Input: Connect the water level sensor's signal output wire to the designated input terminal on the gauge. The gauge supports input signals of 0-190ohm (European standard) or 240-33ohm (American standard). Ensure your sensor matches the gauge's input signal type.

5. Operating Instructions
- Once properly installed and wired, turn on the power supply to the gauge.
- The digital display will illuminate, showing the current water level as a percentage (0-100%).
- The red LED backlight will activate, providing clear readability in low-light conditions or at night.
- Monitor the display for real-time water level information.

6. Maintenance
- Cleaning: Use a soft, damp cloth to clean the gauge's display and housing. Avoid abrasive cleaners or solvents that could damage the surface.
- Waterproof/Dustproof: The gauge has an IP67 rating, making it highly resistant to water and dust ingress. However, avoid prolonged submersion or high-pressure water jets directly on the gauge.
- Connections: Periodically check all electrical connections to ensure they remain secure and free from corrosion.

7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Gauge does not power on. | No power supply; incorrect wiring; blown fuse. | Check power connections, ensure correct polarity, inspect fuses in the power line. |
| Incorrect water level reading. | Sensor malfunction; incorrect sensor type; wiring issue to sensor. | Verify sensor functionality, ensure sensor signal type matches gauge (0-190ohm or 240-33ohm), check sensor wiring. |
| Display is dim or flickering. | Unstable power supply; loose connection. | Check power supply voltage stability, tighten all electrical connections. |
