Hold the outer ear and gently pull it towards the rear of the head to straighten the ear canal.
- Children under the age of 1: hold the outer ear and gently pull it straight back. (Fig. 7)
- Children aged 1 year or older: hold the outer ear and gently pull the ear up and back (Fig.8).
Insert the probe tip very gently and slowly into the ear canal (Fig. 9).
Make sure the probe tip points straight towards the eardrum when you hold it (Fig. 10).
Always insert the probe tip into the same ear, in the same direction and at the same depth.
Note: If you do not point the probe tip towards the eardrum (Fig. 11), the measurement result will be inaccurate.
