I have calibrated this thing 3 times in the first week now. In the tank temperature matched with temp compensation turned to 2.2. Still, it slowly drops each day until I come home and give it a quick shake/tap in the tank. This is in the sump in the lowest flow area I can find. Is there any other solutions? or a special chamber or something? Can you guess what time I tapped the probe to get the bubbles out?
