What to do if METER Weather Station ATMOS 41 is not reading any rain?

  Martin GomezAug 20, 2025
  First, inspect the rain gauge funnel and clear away any obstructions. Ensure the ATMOS 41 is leveled within approximately ±2 degrees in both the X and Y directions for accurate rainfall measurements. If it's not level, drops might miss the electrodes. Check level measurements in the ATMOS 41 data stream to confirm. Gently twist and remove the rain gauge funnel, being careful to unplug the pyranometer connector inside before removing the funnel completely. Inspect for any issues and ensure the gold electrodes are correctly aligned.

  Check the anemometer pathway, ensuring nothing blocks the sonic transducer measurement path. Inspect the sonic transducers for water build-up; if present, gently dab it away with a dry cloth. Ensure the acoustic mirror is clean by flushing it with water and drying it with a cloth. Also, make sure the ATMOS 41 is level.

  Check the sensor's power supply, cable, and the 3.5-mm plug. Verify the data logger wiring connections: Brown to 3.6 V to 15 V power, Orange to digital out, and Bare to ground. If the sensor remains unresponsive, use the ProCheck to ensure it is working correctly.

  Check the temperature needle to ensure it hasn't been pushed in, as this can break the thermistor wires and stop the measurement. Be careful when cleaning around the temperature needle to avoid damaging its delicate lead wires.

Why is my METER ATMOS 41 Weather Station not reading rain accurately?

  Julie ScottAug 31, 2025
  If your METER Weather Station ATMOS 41 is not reading any rain or is measuring it inaccurately, first, clear any obstructions from the rain gauge funnel. Ensure the ATMOS 41 is within approximately ±2 degrees of dead level in both the X and Y directions. Use the internal level measurements in the ATMOS 41 data stream to confirm it's level. Gently twist the top of the weather station and remove the rain gauge funnel to inspect for any apparent issues and check that the gold electrodes are aligned correctly. You can also check the drip counter calibration using the procedure described in How to check the drip counter calibration (metergroup.com/atmos-41-drip-counter-calibration).

  If your METER Weather Station ATMOS 41 is not responding, verify the power supply to the sensor. Inspect the sensor cable and stereo plug connector for any damage. Try using a different port on the data logger. Ensure the data logger wiring is correctly connected, paying attention to these connections: Brown—3.6- to 15.0-V power supply, Orange—digital out, and Bare—ground. If the sensor still doesn't respond, use the PROCHECK to ensure it's functioning correctly.

  Brandon EdwardsSep 4, 2025
  If your METER Weather Station shows no wind speed, check the anemometer pathway for any obstructions blocking the sonic transducer measurement. Inspect the sonic transducers for any water accumulation and gently dab it away with a dry cloth. Ensure the sintered glass plate is clean by flushing it with water and drying it with a cloth. Make sure the ATMOS 41 is level.
