Why does AquaCalc reset the timer and counter during a measurement?
There are two primary reasons: • The cat whisker hairs are dirty. When using a cat whisker be sure that the cat whisker is adjusted properly and free of oil and dirt. The proper adjustment of the cat whisker allows contact to be made through 30 degrees of rotation (dwell). • You are in a turbulent flow condition. If the above doesn’t fix the problem, you may be trying to measure in a surging stream condition. If the AquaCalc sees rapid changes in the velocity of the stream that exceed 50% of the previous cup rotation, it will reset itself in order to get a stable measurement. Move left or right to a new vertical distance and measure again. This problem is more common with the Pygmy meter. For more information on AquaCalc resetting problems click here. If you frequently perform measurements in turbulent flow conditions, you should consider updating your firmware EPROM to the latest version which has greatly improved turbulent flow handling capabilities.
