- Rain Collector II
- Installation manual
- Components
- The Rain Collector II includes the following components. Please make sure you have all listed components before continuing.
- Rain Collector Internal Components
- The illustration below shows the internal components of the rain collector, many of which are referenced in this manual.
- Rain Collector Internal Components
- You may need some of the following tools and materials to install the rain collector.
- The rain collector tipping bucket mechanism contains a standard measurement weight magnet that takes measurements in .01” for every tip of the bucket. The Complete Weather Wizard III (7425CS) assembly contains a metric rain adpater that adjusts the...
- Open plastic tipping mechanism arms, pull out magnet
- Separate magnet from one end cap
- Insert magnet with other end cap into metric measurement adapter
- Open plastic arms to insert metric measurement adapter, with adapter in “V” position
- Rainfall Calibration Number
- Each station uses a rainfall calibration number (CAL) to determine how much water each bucket tip (i.e., pulse) represents.
- Calibrated Rainfall = Number of pulses x (1/CAL)
- The default rainfall CAL of 100 works for the 0.01" rain collector. If you have a 0.01" rain collector you do not need to adjust CAL at all.
- If you install the metric adapter to your rain collector, first adjust the console to display rainfall in millimeters (press RAIN then UNITS until it displays mm) and then change CAL to 0005. (To change CAL, press and hold the RAIN button until CAL a...
- Note: Make sure you display rainfall in the appropriate units of measure before changing CAL; otherwise you will be setting the wrong calibration number. If, by mistake, you change CAL before switching to the appropriate units, you can rectify the er...
- Once the console is calibrated for 0.01" (default) or 0.2 mm, you can switch the display units as often as you like; the console accurately converts rainfall amounts regardless of the type of rain collector you use.
- If you purchased a Monitor or Wizard station prior to 1994, it may be pre-calibrated for an earlier model rain collector. See “Calibration of Older Model Weather Stations” on page 10 for instructions.
- Testing the Rain Collector II
- Before installing the Rain Collector II, test the unit. If you are replacing a rain collector you previously installed, make a note of the total rainfall amount displayed. You may want to reenter this amount after you test the rain collector.
- Remove the Cone from the Base
- 2. Carefully cut and remove the plastic tie which holds the bucket in place during shipping.
- 3. Attach the rain collector cable to the appropriate connector on the junction box.
- 4. Consult your station manual or system installation manual.
- 5. Press the appropriate key on your console as necessary to display rainfall.
- 6. Press UNITS if necessary to display rainfall in the rain collector’s native unit of measure.
- 7. While watching the display on your console to see if it changes, slowly tip the bucket until it drops to the opposite side. If the display does not change, you may be tipping the bucket too quickly. Try again, more slowly this time.

- Follow the instructions in this section to install your rain collector. Make sure you read “Choosing a Location for the Rain Collector” on page 7 as it contains important information concerning placement of the rain collector.
- The illustration below shows a typical rain collector installation for the Weather Wizard III and Weather Monitor II.
- Typical Installation
- Keep the following in mind when choosing a location for your rain collector:
- Installing the Rain Collector II
- 1. If you have not already done so, separate the cone from the base.
- 2. If necessary, disconnect the rain collector cable from the junction box.
- 3. Locate a suitable mounting surface, using the guidelines above.
- 4. Place the base on the mounting surface and mark the location of the four holes (the base has eight to choose from) you will use to secure the base.
- 5. Make pilot holes using a 3/32" (2 mm) drill bit. You should make the pilot holes about 1/2" (12 mm) deep.
- 6. Fasten the base to the mounting surface using the #8 x 3/4" screws provided.
- Installing the Rain Collector II
- Fasten Base to Mounting Surface
- 7. Attach the rain collector cable to the appropriate connector on the junction box.
- 8. To be certain the rain collector is functioning properly after installation, retest the unit as described “Testing the Rain Collector II” on page 5.
- 9. Once you are sure the unit is functioning properly, place the cone back onto the base by putting the latches on the cone into the latch openings in the base and rotating the cone clockwise until the latches “lock” into place.
- 10. Place the debris screen, points down, into the cone. The screen prevents large bits of debris from blocking the funnel hole.
- 11. To prevent fraying or cutting of the cable where it is exposed to weather, it is important that you secure it so it doesn’t whip about in the wind.
- Extending Cable Runs
- Note: Climbing on your roof may be hazardous. If you are uneasy about installing your unit please have a qualified professional complete the installation. Davis specifically disclaims any liability for injury or loss resulting from the installation o...
- Adjusting the Rain Collector II
- The Rain Collector II is calibrated at the factory so the bucket tips (and records rainfall) for each 0.01" (or 0.2 mm if the metric adapter has been fitted) of rain. To adjust the calibration slightly, use a 3/16" (or 5 mm) wrench to rotate the adju...
- Adjustment Guide
- Note: Modify both adjustment screws by the same amount.
- Note: Do not compare rainfall readings to reading obtained from television, radio, newspapers, or neighbors readings. Such readings are not located in your specific environment and therefore are not an accurate measurement of the weather readings tak...
- Maintaining the Rain Collector II
- For greatest accuracy, you should thoroughly clean the Rain Collector II at least once or twice a year.
- 1. Disconnect the rain collector cable from the junction box.
- 2. Separate the cone from the base.
- 3. Use warm soapy water and a soft cloth to clean pollen, dirt, and other debris from the cone, cone screens, and bucket.
- 4. Use a pipe cleaner to clear the funnel hole in the cone and the drain screens in the base. When all parts are clean, rinse with clear water.
- 5. Reattach the cone and replace the screen.
- 6. Reconnect the rain collector cable to the junction box.
- For greatest accuracy, you should thoroughly clean the Rain Collector II at least once or twice a year.
- Using the Rainfall Function
- To Clear Rainfall
- Rain and total rain are independent of each other. You must clear each register separately.
- Daily Rainfall Cleared
- Note: Performing a “total clear” on the weather station does not clear rainfall.
- Calibration of Older Model Weather Stations
- This information applies only to users of the Weather Wizard II-S, Weather Wizard III, and Weather Monitor II manufactured prior to April, 1993. To check if your station meets this criterion, press the RAIN button on the console. If, when set to inch...
- When using the 0.01” setting of the Rain Collector II with an older model station, note that the station is pre-calibrated for an earlier model 0.1" rain collector. To re-calibrate your station, first set the display to inches, then change CAL to 0...
- When using the 0.2 mm setting of the Rain Collector II with an older model station, note that the station stores rainfall amounts in 0.2 mm increments but displays amounts rounded to the nearest whole millimeter.
- Note: Keep in mind when testing the rain collector with older weather stations that the display adds 1 mm for each 5 tips of the bucket. Because the display rounds, however, the first change occurs after the bucket tips 3 times (0.6 mm rounded to 1 mm).
- To calibrate your station for rounded millimeters, set the console to display rainfall in millimeters and then change CAL to 0005. (See “Rainfall Calibration Number” on page 4 and/or your station user’s manual for instructions on how to change ...
- If you want your station to display rainfall in tenths of a millimeter, you can “trick” it into displaying in 0.2 mm increments. To “trick” the station, first display rainfall in INCHES and then enter a CAL value of 0005. To display rainfall ...
