What to do if my Airflow Measuring Instruments have no display?
- RrdiazAug 10, 2025
If your Airflow Measuring Instruments unit shows no display, first ensure the unit is switched on. If the display remains off, replace the batteries, as they may be low or dead. Finally, check and clean the battery contacts, as dirty contacts can prevent the unit from powering on.
