My rain gauge appears to be under reporting.
- If the display is showing rain rate, change to daily rain to track the rain accumulation better.
- Make certain the rain gauge is level. If not perfectly level, the tipping mechanism will not work properly and under report rain.
- Make certain there are no obstructions in the funnel and tipping mechanism.
- In heavy downpours or sideways wind, the rain droplets can “bounce” out of the rain gauge. Use Teflon spray:https://www.amazon.com/DuPont-Silicone-Lubricant-Aerosol-14-Ounce/dp/B00D3ZKVASto prevent accumulation of the droplets on the walls of the rain gauge.
