Output voltage Air Level means the output level in the condition where nothing is placed against the sensor
surface (in other words, in air). This rating value is obtained by measuring 32 points within one line of the
sensor output and then taking the average.
The gain setting for this measurement is (011).
2
Output voltage Water Level specifies the degree to which the output level changes from the Air Level when
a drop of water is placed on the sensor surface. However, it is unrealistic to place a drop of water on each
sensor surface when sorting products, so 32 virtual capacitors (parasitic capacitance equal to the level
when a drop of water is placed on the surface) are built into the sensor chip, and the average of these
output values is calculated. The difference from the Air Level noted above becomes the Water Level.
The gain setting for this measurement is (011).
