Before you measure

• Wait at least 30 minutes after bathing, feeding or physical activity. Measuring immediately after any of these may give an inaccurate reading.
• If the person or the device has come from a very cold or very hot place, allow both to stabilise at room temperature for several minutes.
• Measure in a stable, draft-free environment. Air flow from a fan or air conditioner can alter the reading.
• Make sure the underarm area is clean and completely dry, and remove bulky clothing from the measurement area.
• During the measurement, keep mobile phones and other devices that emit electromagnetic fields at least 30 cm away from the thermometer. Closer than that may cause incorrect operation or an inaccurate reading.

Placing the device

1. Position the thermometer in the strap so that the sensor part passes through the opening and is secured within the small fastening loop.
2. Place the strap around the patient so that the sensor sits firmly under the armpit, in direct contact with bare skin.
3. Adjust for a snug but comfortable fit — tight enough to keep full skin contact, but not so tight that it restricts breathing or causes discomfort.
4. A few seconds after correct placement, new temperature readings appear in the app.

Reading the temperature

It takes about 2 minutes to get a steady temperature readout. Watch the live display in the app: the value rises and then levels off at a plateau — that stable value is the measurement. If you reposition the device, allow it to settle again.

The measurement is recorded automatically and saved to the history with a timestamp.

Confirm who you are measuring

Before you record, export or act on a reading, verify the patient name or identifier shown at the top of the screen. See Confirming the Correct Profile Before You Act on a Reading.

Tips for accurate results

• Always use the same armpit so readings can be compared over time.
• Keep the arm closed against the torso and minimise movement during the reading.
• Make sure the sensor touches bare skin only, not clothing.
• For infants and children, gently hold the arm in place, or measure while the child is calm or asleep.

Continuous monitoring

Attach the thermometer with the elastic strap, confirm the connection in the app and set your alert threshold. Keep your phone within Bluetooth range. If the connection is temporarily lost, the thermometer stores measurements in its 48-hour internal buffer and synchronises automatically when the connection is restored.

Do not wear the device continuously for more than 24 hours.
