2. 3 How it works The Altis v4 uses a modern fast digital pressure sensor which allows it to sense very low pressure differences This gives the unit an altitude resolution below 0 25m with sample rates as low as 0 1s Since atmospheric pressure changes over time these changes will affect your measurements For this reason long term measurements may not be precise enough However the altitude for short term flights which are common in R C aircraft can be recorded very precisely The measured altitude is stored in the high capacity internal memory which allows approx 15 hours of recording with the fastest sampling rate 0 1s After the Altis v4 is connected to a power supply it will initialize in the first 3s During initialization the reference altitude and a zero throttle level are measured Note It is necessary to keep the throttle on your R C transmitter turned off during this phase It is recommended to set the initial altitude before each flight by disconnecting and re connecting the power supply Hardware description Connectors of your Altis v4 Your Altis v4 has 5 connectors They are shown in Fig 1 IN input signal from the R C receiver Power to Altis v4 is provided from the receiver via this connector OUT output signal to ESC Electronic Speed Control USB micro Connects the Altis v4 to a computer via USB COM A COM B Molex connectors for connection with telemetry equipped receivers as well as
