yes with a "zip-bag", it was rougly -0,4 to reach 0 celcius on both BUT
with a salt test that should result at 84,6% both were measuring rougly 1% to much WITHOUT offset and rougly 4-5% to much with the right offset.. so either the icewatertest was wrong or the factory calibration was way off, or the offset just needs second point at 20-30 Celcius to compensate the non-linearity
