Cleaning the filter of the Apogee SIF-111 Infrared Radiometer is an important maintenance task to ensure accurate measurements. The filter can become partially blocked by dew, frost, salt deposits, dust, dirt, or insects. Here is the recommended procedure for cleaning the filter:

1. Remove the sensor from its mounting location and disconnect it from any power source.
2. Inspect the filter for any visible signs of blockage or debris.
3. If there is dew or frost on the filter, allow it to naturally evaporate before cleaning.
4. If there are salt deposits on the filter, use a dilute acid solution (such as vinegar) to remove them. Do not use solvents like alcohol or acetone for salt deposits.
5. If there is dust or dirt on the filter, gently clean it with deionized water, rubbing alcohol, or acetone. Use a cotton swab dipped in the appropriate solvent and apply gentle pressure to remove the debris. Avoid using abrasive materials that may scratch the filter.
6. If there are spiders, insects, or nests in the aperture leading to the filter, apply a repellent around the aperture entrance (not on the filter) to prevent their presence.

Remember to always handle the filter with care and avoid applying excessive force or using abrasive materials that could damage it. Regular cleaning and maintenance of the filter will help ensure accurate measurements from the Apogee SIF-111 Infrared Radiometer.
