You must measure the humidity. I like the inexpensive combination humidity and temperature gauges one can buy at most hardware stores and stores like
Wal-Mart. Do not use this device for measuring temperature! It is very inaccurate and responds too slowly to changes in temperature.
The quotto is from Alan Standford's web Page Brown Egg Blue Egg --
I made this mistake last year used a hydrometer and it was 2 degrees low...
Cost me a whole load of silkie eggs-
The R-Com should be preset and ready to roll -
The good part about
Brinsea is they have excellant customer service if you are unhappy.
As many know I started out with an R-Com and I felt like you ,with the money invested i wanted it to work --
Fertile Egg follow directions 21 days later I wanted a chick --
This was not the case for me so first the Company swapped me units --the second was no better then the first so I traded it for a regular
Brinsea which has been awesome---
I am betting your R-Com is correct I would set a group of test eggs It will probabally not need any adjusting--
I know a few people use the R-Com 20 and seem to have great results --
