Note: The table shows the possible combinations of Pressure Measurement Rate and oversampling when no

temperature measurements are performed. When temperature measurements are performed the possible

combinations are limited to Ratetemperature x Measurement Timetemperature + Ratepressure x Measurement

Timepressure < 1 second.

The temperature measurement time versus temperature oversampling rate is similar with pressure

measurement time versus pressure oversampling rate
