How many selectable height range functions does the FZU-39/B proximity sensor have?

The FZU-39/B proximity sensor is designed with a specific number of selectable height range functions that allows it to operate effectively under various conditions. In this case, the correct answer indicates that there are 10 selectable height range functions. This feature is crucial as it enables the sensor to tailor its performance depending on the operational requirements, such as the environment and the specific targets being engaged.

The existence of 10 different height range functions enhances the flexibility and adaptability of the FZU-39/B sensor, allowing it to be utilized across a range of scenarios and ensuring that it can effectively recognize the proximity of targets at differing altitudes. Such functionality is paramount in precision munitions and contributes to maximizing effectiveness while minimizing collateral damage.

In contrast, the other options incorrectly specify a different number of selectable height range functions, which would imply a limitation in the operational adaptability of the sensor that is not consistent with its design specifications. The accurate identification of these functions is essential for munitions systems personnel to ensure that they are employing the sensor to its fullest capability.
