The rain gauge features a small circular spirit level on the base. Loosen the locking nuts on the three adjustable feet, adjust them until the bubble is centered in the spirit level, and then retighten the locking nuts to secure the position.
EML recommends re-calibration every 12 to 24 months depending on the application and environmental conditions. Calibration involves ensuring the tipping bucket mechanism triggers at the correct volume of water.
Regularly inspect the funnel and filter gauze for debris such as leaves or dirt that may block water flow. Clean the filter by removing the end cap and rinsing the mesh. Also, verify that the gauge remains level during site visits.
The ideal site is on level ground with a uniform scattering of objects in the surrounding area to reduce wind speed without causing turbulence directly near the gauge. Avoid placing it too close to large obstructions like buildings or trees; the distance to the nearest object should be at least twice the height of that object.
