I have an existing digital electronic OAT gauge in the airplane and have recently installed your OAT along with the EDC-10A. I have noted that in flight the Dynon unit shows a higher temperature than the existing but that on the ground both are nearly the same.
Today I used an ice water bath to "calibrate" both units at my main temp of interest - freezing. The existing one showed 0C and the Dynon +6C so I reset it per the installation manual back to 0C.
Later today while on the ground I compared the temperature on AWOS to my existing digital OAT. Both were within one degree C but the Dynon was showing about 4 degrees higher. I am assuming the Dynon is accurate at freezing since I set it to zero with the probe in ice water. I am surprised that at today's ambient temp of +18C it is still off by several degrees. Is this common or is something else going on?
