carried out. The automatic test interpretation follows the latest 11 level ATS (American

Thoracic Society) classification. Each test can be repeated as required. The best parameters

are always available for review. The normal (predicted) values can be selected from several

normal “sets”. For example, within the European Union the majority of doctors use the ERS

(European Respiratory Society) predicted values.

The device has two batteries:

• Main power: 9V battery (1 battery is required)

• Memory back up: lithium battery type CR2032 of 3V. The battery life is about 10 years,

depending on the use of the device
