If your temperature seems too high or low on your incubator, check your sensor.
When setting up your Little Giant® incubator it is very important to make sure all cables are securely connected as it is possible they could become loose. Also be sure to make sure the sensor on the lid of your unit is hanging freely and not caught in any other cables.
The sensor can only measure the temperature and humidity at its specific location in the unit, so it is important that it hangs freely and is not tangled up in a higher location.
Temperatures can vary inside your unit depending on the height and distance of your sensor from the center of the unit.
Secondary Thermometer
For best results, we recommend the use of a trusted calibrated second thermometer in addition to the one built into your Little Giant® unit. There are combination units available that will measure both temperature and humidity. If a combination hygrometer/thermometer is unavailable in your area, a common household medical thermometer will work just fine. We recommend placing your secondary thermometer at egg height in the middle of either window.
Place your secondary thermometer at egg height in the center of either window as marked by the green circles. The second thermometer will help to give you a more accurate view of the temperatures at egg level in your unit.
Why?
The hanging sensor gives an accurate reading but can only measure the temperature at its specific location within the unit. Temperatures may vary inside the incubator depending on the environment of the location where you choose to keep your unit. For best results, we recommend consulting with a local expert in your area, keeping your incubator in a room with a consistent temperature between 70-85 F, using a second thermometer located at egg level, and rotating the location of your eggs in the unit when turning.
In addition to the small differences in temperature due to location, you may notice the temperature of your secondary thermometer go up and down a few degrees as the incubator runs. This is due to the normal heating cycles of the unit and is okay as long as your average temperature is at your desired set point.
To regulate heat in your Little Giant® Incubator, the system runs in cycles. The hanging sensor will read the temperature in its location in the incubator. When the incubator sensor detects a temperature below the set temperature, it will activate the heater raising the temperature until the temperature detected by the sensor matches the set temperature. It will then turn the heating component off until the temperature dips below the set temperature. Depending on the temperature and humidity in your incubator’s location, this cycle can happen more or less frequently. The average temperature is one of the important factors for the incubation of your chicks and is why we recommend you take an average reading over the course of 10 minutes when using the worksheet.
