You get frustrated just like me. You said you called the factory... did they tell you how they test the temp/hygrometers and they are accurate?I tried three times. I unpluged the bator and pluged it back in while holding down the up/down button. which brings up 2.9. Then I pressed the up button but it doesn't change the numbers?What am I doing wrong? O.k I don't feel so dumb! I called company and they couldn't figure it out either.
I have tested my 4 incubators using 2 of those temperature checking eggs at the same time. When the eggs were new late winter they read exactly the same.
I put the batteries in this week to use them and they are 1.1 degree different. One of the egg thermometers matches that incubator.
In my #2 Genesis, I have the incutherm temperature/hygrometer that I bought new this year. That incubator has a new replaced thermostat sent by the factory this winter.
The temperature of the incubator is reading .5 degree lower than the incutherm gauge.
The humidity in the incubator is 10% less than the incutherm gauge. THAT concerns me.
I had tested the incutherm gauge and 4 cheapo crappy accurite temp/hygrometer gauges using the salt method a few weeks ago. The incutherm gauge was perfect.
Maybe I better check it again.
