How to assemble the Davis Rain Gauge

The Davis Rain Gauge is an important sensor for accurately measuring rainfall.

In this step-by-step guide, we will walk you through the process of assembling the Davis Rain Gauge, ensuring proper installation for precise rain measurement. 

To provide you with a visual demonstration, feel free to refer to a video below that you can follow along with. 

Before we begin, please gather the following tools and components:

• Crimper
• Measuring tape
• Pliers or edge cutters
• Rain bucket cover
• Rain sticker
• New plug
• U-bolt, nuts, washers, and plate (from the Davis package)
• Bird spikes (for deterring birds from nesting)
• Filter (for new model)

Step 1: Preparing the Rain Bucket:

1. Unbox the rain bucket and locate the rain bucket cover.
2. The rain bucket cover funnels water down through the hole into the cup.
3. Ensure the rain bucket is level by checking the bubble inside the sensor. It should be inside the black circle, indicating levelness.

Step 2: Understanding the Tipping Mechanism:

1. The tipping mechanism inside the rain bucket records rainfall.
2. The mechanism contains two magnets—one at the bottom of the Tipper and another nearby.
3. As the bucket tips, the magnets pass each other, recording 0.2 millimeters of water each time.
4. To test the sensor, manually tip the bucket and calculate the amount of rainfall based on the number of tips multiplied by 0.2 millimeters.

Step 3: Installing the Filter:

1. For the new model with an error code, push the filter into the designated slot and twist it to lock it in place.
2. With the older style, simply place the filter inside the rain bucket.

Step 4: Adjusting the Cable Length:

1. Measure and cut the cable to 900 millimeters from the end of the rain sticker.
2. Use side cutters or pliers with a cutting tool to make the cut.
3. Dispose of the excess cable and unnecessary parts responsibly.

Step 5: Crimping and Wrapping the Cable:

1. Use a crimper with the correct settings for the cable thickness.
2. Strip the end of the cable and slide it into the crimper with the yellow side facing outward.
3. Crimp the connector tightly using all the clicks on the crimper.
4. Peel off the rain sticker backing and wrap it around the cable connector.

Step 6: Feeding the Cable and Attaching the Plug:

1. Remove the plug from the rain gauge and feed the cable through the designated hole.
2. Pass the cable through and secure the plug back in place.
3. Ensure the cable is held securely.

Step 7: Handling the Tipper Assembly:

1. In case of damage, the tipper assembly can be replaced by cutting a standard piece of metal in half.
2. Insert one of the 15 rods into the middle of the rain bucket.
3. Insert additional rods evenly around the sides until all slots are filled.

Step 8: Installing Bird Spikes:

1. Place bird spikes in the middle section of the rain gauge to deter birds from nesting.
2. Ensure the spikes are securely in place but do not cause harm to the birds.

Step 9: Attaching the Aero Cone Cover:

1. The Aero Cone Cover can only be attached in a specific orientation.
2. Align the cover correctly and slide it into the slots until it clicks into place.
3. If you encounter difficulty, rotate the cover 90 degrees and try another slot.

Step 10: Tapping and Final Check:

1. Give the rods a gentle tap to ensure they are securely in place.
2. This step helps to ensure the rods do not fall out during use.
3. Verify that all components are properly assembled and secured.

As you have successfully assembled the Davis Rain Gauge, now it is ready to be attached to the mounting bracket for accurate rainfall measurement.
