What air pressure value should I enter in the SDR software? Where do I get it from?
By default, the air pressure of the applied calibration data set is shown in the Measurement Settings. However, if you know the current air pressure value, you can enter it in the software for more accurate oxygen value calculation. You will have to measure the air pressure with an external device, as the SDR does not have a built-in pressure sensor.
