OK, so I got the HB barometer and had it calibrated by the vendor. Hooking it up though, it displayed an almost constant 28.39 inHg, while three local weather stations (same altitude, about 2 miles from me) say it should be 29.76 (!).
After letting it sit for a day or so, it still gives me this huge offset and nothing changed. Now I want to check the voltages are correct, but I could not use the OneWireViewer for this as it could not detect the TEMP08 that I use to interface with the sensors. Is there a way to read the voltage using a multimeter directly on the board? Which pins should I use to get the correct voltage?
