What should be done if the air content exceeds the 9% range of the meter?

If the air content exceeds the 9% range of the meter, adding calibrated cups of water is an effective way to adjust the measurement. This approach works by increasing the density of the fluid sample being measured, thereby diluting the concentration of air in that sample. By adding water, the overall mixture becomes more stable for accurate readings, providing a better representation of the sample's true air content.

This method is particularly valuable in ensuring that the measurement tools remain effective and that the results obtained fall within the acceptable range for accurate testing. Calibrated cups ensure that you are adding a precise amount of water, which is crucial for maintaining the integrity of the measurement and ensuring consistency in results.

Other strategies, such as replacing the meter or recalibrating it, may not directly address the immediate issue of high air content and would not resolve the problems associated with inaccurate readings at that time. Thus, using calibrated cups to dilute effectively manages air content.
