Adjusting OAT Offset
SkyView provides the ability to adjust the displayed OAT +/- 20F (11.1C). This adjustment is applied across the OAT’s entire temperature range. This adjustment can be made under SETUP MENU >HARDWARE CALIBRATION > ADAHRS CALIBRATION > OAT OFFSET.
(I know it's hard to look this stuff up ... NOT!)
I just want to make sure it calibrated correctly, I am going to check it with an alternate temperature sensor. The sensor is mounted on the side of the fuselage on an RV3B.While you are adjusting it, it is not often you need to do that.
Probe placement is usually the biggest cause for error. Where is your probe mounted and on what kind of plane?
Tucked under the cowl cheek I guess it was install ed so wiring does not need to be extended.Is it exposed to sunlight?
It is best placed under the ingot near the pitot tube or somewhere like that. Never near the fuse under the plane where exhaust gas gets it, and never under a fairing that gets hot.
Thanks, I will run some tests with an electronic fridge thermometer and tape the probe under the wing. I will compare results before I commit to moving the Dynon probe.That location will not read correctly. Air spills out of the intake, some can leak through the cowl seam and ideally the other side of the temp sender would also be at ambient temperature. Yours is right where your cabin heat is greatest when used. The installation manual says the wires can be extended with regular wire. I ran mine out to the aileron inspection bellcrank area. Out of the sun and all air inside and out of the wing is ambient there. It has been completely reliable.
