Product Notes
The EggTemp-RH consists of a temperature and humidity data logger inside an egg shaped
enclosure to simulate the humidity and temperature affects of a real egg.
LEDs
Once started, the green LED will flash every two seconds to indicate that the device is
running. The red LED will flash in two second intervals if there is an alarm condition.
Alarm Settings
To change the settings for the temperature alarm:
- Select Alarm Settings from the Device menu in the MadgeTech software. A window will
appear allowing the customer to set the high and low temperature alarms.
- Press Change to edit the values.
- Check Enable Alarm Settings to enable the feature. The values can be entered in the
field manually or by using the scroll bars.
- Click Save to save the changes. To clear an active alarm, press Clear Alarm.
O-Rings
O-ring maintenance is a key factor when properly caring for the EggTemp-RH. The o-rings
ensure a tight seal and prevent liquid from entering the inside of the device.
Please refer to the application note “O-Rings 101: Protecting Your Data”, found on the
MadgeTech website, for information on how to prevent O-ring failure.
