Put the salt in the container. Put a few drops of water onto the salt, just to moisten the salt. Then place the container inside the baggie. Now place the gauge in the baggie. Make sure you have this in a spot somewhere that no small kids can get to or that it can be knocked over. Wait between 4-6 hours. When you check it after that amount of time, look in the bag without opening it.Your gauge should be reading 75%. If it IS NOT, then thats how much your gauge is off by. To fix this you can get a small screwdriver and turn the screw on the gauge. If it's off by 7%(68%) then turn it so it reads 7% higher.

OK.. I must be missing something... I missed the part on why you need TWO baggies.
As I go over the instructions it says add salt to cap lid... add a few drops of water (I'll assume 3 or 4..????)
Then it says put lid in baggie,.... then put gauge in baggie.
DO you put the whole thing in TWO baggies,.. put the lid in one baggie, and then put the gauge in an different baggie and put it in the first with the lid (although this is the only way I can see using two baggies to any effect, it would seem that having the gauge sealed in a ggie by itself would have no effect..
Anyway,.. you see why I am confused.
Please advise
