Using your Closer to Nature Digital Thermometer
An incorrect reading (around 2°C lower) can be measured if the ear canal is not straightened correctly. The ear canal is not identical in each ear; this can result in a slight difference in some individuals.
It is therefore important to straighten the ear canal prior to taking a reading. For children under 2 years old, gently pull the ear back. User technique is critical.
The instructions for use advise that three readings should be taken, with the highest being the one which is registered. The unit measures the infrared heat generated by the eardrum.
I seem to be getting a constant “LO” or “HI” reading?
Firstly, make sure that you have a new hygiene cover in place (you require a new cover for each new reading) and the thermometer has been sat in the same room for at least 15 minutes for it to detect the ambient room temperature. Don’t hold the thermometer in your hand for more than 3 minutes as this can affect the reading. Ensure that the ear canal is clean and straight as the probe needs to be aimed at the eardrum. If your little one is under 2 then you need to gently pull the ear back. If they are over 2 then you will need to pull up and back to straighten the canal.
How long should the battery last?
The battery can last up 3000 readings
How do I change the battery and what battery can I use?
The thermometer requires 1 x CR2032 battery. When placing the new battery into position, please ensure that you tuck the battery under the small metal hook before pushing it into place.
How can I switch between Fahrenheit and Celsius?
In “power off” mode press and hold the “scan” button, then press the “On/Mem” button for 3 seconds whilst still holding the scan button. The “C” will change to “F” and vice versa.
- The ear canal needs to be clean
- The thermometer lens needs to be clean and undamaged
- A fresh hygiene cover must be used each time
- The unit must be equilibrated to the temperature of the room where readings are taken
- Accidentally pressing the on/mem button instead of the scan button will show a previous reading from the memory rather than take a new reading
- A higher temperature will be recorded in an ear that a child has been laying on compared to their other ear
