1. If the display is showing rain rate, change to daily rain to track the rain accumulation better.
  2. Make certain the rain gauge is level. If not perfectly level, the tipping mechanism will not work properly and under report rain.
  3. Make certain there are no obstructions in the funnel and tipping mechanism.
  4. 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.
