Setup

Before first use, or if the device is not powering on, ensure the 9V battery is correctly installed.

1. Locate the battery compartment on the side of the reel. It is usually covered by a small panel.
2. Carefully open the battery compartment.
3. Connect a 9V battery to the battery clip, ensuring correct polarity.
4. Place the battery inside the compartment and close the cover securely.

Operating Instructions

The Water Level Meter operates on the principle of electrical conductivity. When the probe's contact point touches the water surface, it completes an electrical circuit, activating an audible buzzer and a visual indicator light.

1. After ensuring the coil has been rotated and the steel ruler cable is ready, press the power button to turn on the device.
2. Hold the steel ruler cable and slowly lower the probe into the water pipe or well.
3. Continue lowering until the sounder emits a continuous beep and the indicator light flashes. This signifies that the probe's contact point has reached the water surface.
4. Read the depth directly from the steel ruler at the pipe mouth. This reading represents the distance from the pipe mouth to the underwater level.

Important Notes for Measurement:

• When the probe touches water, both the sounder beeps and the indicator flashes. Slowly lower the cable further to precisely identify the exact moment of contact for accurate reading.
• The accuracy of the reading depends on the timely determination of the buzzer and indicator light activation. Operator proficiency is key; practice is recommended for optimal accuracy.

Maintenance

Proper maintenance ensures the longevity and accuracy of your Water Level Meter.

• Battery Conservation: To preserve battery life, immediately turn off the device after completing measurements.
• Cleaning: Keep the probe and steel ruler cable clean after each use.
• Cable Storage: Neatly wind the steel ruler cable around the reel after use.
• Cable Handling: Avoid bending the measuring cable, especially near the probe head, to prevent damage.
• Probe Care: Handle the probe gently to avoid severe vibration or impact. If the probe experiences issues, contact the manufacturer for service.

Receipt and Storage

• Initial Check: Upon receipt, verify that the instrument count matches the packing list. Report any discrepancies to the factory immediately.
• Storage Conditions: Store the instrument in a room with a temperature range of -10°C to +40°C.
• Environmental Requirements: The room's humidity should not exceed 80%, and it must be free of corrosive gases. Ensure the storage area is dry and well-ventilated.

Specifications

Troubleshooting

• No Buzzer/Light Activation:
  • Check battery installation and ensure it is a fresh 9V battery.
  • Verify the power switch is in the "ON" position.
  • Ensure the probe is making proper contact with the water. The water must be conductive.
• Inconsistent Readings:
  • Clean the probe tip thoroughly to remove any residue that might affect conductivity.
  • Ensure the cable is not bent or damaged, especially near the probe.
  • Practice the measurement technique to improve consistency in identifying the exact water contact point.
