In the BMP388 data sheet (linked here for convenience) in Section 1 "Specification," there are "operational" and "full accuracy" ranges listed for temperature, but only "full accuracy" is listed for pressure. Is there a pressure operational range?
The reason for my asking is because I have recently collected data which corresponds to pressure values as low as 4882 Pa (48.82 hPa) which is much lower than the datasheet stated range of 300...1250hPa.
Are my measurements of 48.82hPa valid, and if so what is the relative accuracy I should expect? I see the data sheet states typical relative accuracy of pressure in the range of 900...1100hPa, but nothing regarding beyond that range.
I am fairly confident in these measurements (+/- 3hPa) as this was part of an aloft balloon experiment with GPS altitude measurement.
