To calibrate the rain gauge on the AcuRite 06014 Home Weather Station, follow these steps:
1. Ensure that the 5-in-1 sensor is perfectly level using the built-in bubble level.
2. Use a compatible companion unit or AcuRite software to monitor during calibration.
3. Make a pinhole in the bottom of a plastic cup. Hold the cup over the rain gauge and fill it with exactly 1 cup (8oz) of water, allowing the water to drip into the rain gauge. You should hear the internal buckets tip and see water drain through the rain gauge.
4. A few seconds after each bucket tip, the companion unit displays rainfall in approximately 0.01” or more increments.
5. The cup of water should take more than 20 minutes to empty; a quicker period will result in an inaccurate calibration. Try to simulate a normal steady rainfall. When the cup is empty of water, the companion unit should register 1.06”.
6. There should be nearly an equal number of water drops (about 25 water drops) between bucket tips. If not, adjust the calibration screws on the bottom of the 5-in-1 sensor until an equal number of water drops are tipping the buckets.
7. If the rain gauge doesn’t register close to 1.06”, make an equal adjustment to the two calibration screws on the bottom of the 5-in-1 sensor. Turning screws clockwise increases rainfall; counter-clockwise decreases rainfall.
8. To adjust the rainfall reading by 2%, turn both screws 1/8 of a turn.
9. To adjust the rainfall reading by 4%, turn both screws 1/4 of a turn.
10. To adjust the rainfall reading by 8%, turn both screws 1/2 of a turn.
Please refer to the AcuRite 06014 Home Weather Station Instruction Manual for more detailed instructions and illustrations on calibrating the rain gauge.
