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: When you do not point the probe tip towards the eardrum (Fig. 11), the measurement result will be inaccurate.
