You can configure the sensor behavior for the event that no measurement is possible.
The following options are available:
Output minimum/maximum value (clamp)
A replacement value is output in place of the distance value (see value for “Signal too
weak” in the previous table).
This behavior corresponds to the factory settings.
Hold last measured value
The last valid distance value is frozen and output again (held). This process repeats
until it is once again possible to run a measurement.
Temporarily hold the last measured value (HoldX)
The last valid distance value is frozen and output again (held). This process repeats
until it is once again possible to run a measurement. However, it does not continue
beyond a preset time span. If a measurement is still not possible after this time has
elapsed, the minimum/maximum value is output.
The maximum time span is adjustable. It is the product of the configured measurement
integration time and a selectable factor. This factor is one of the following values: 2, 4,
8, 16 or 32.
Example
Integration time: 3.33 ms (medium speed), factor: 8 (HoldX8)
Maximum holding time = 8 x 3.33 ms = 26.64 ms
