It is recommended to periodically clean the instrument with a damp cloth, to ensure the instrument user
interface and keypad is clean and legible.
The particulate exit aperture is protected by a stainless-steel grille to minimise the ingress of flora and
fauna into the XD One device. It is recommended that the grille it is checked and cleaned during
maintenance periods to ensure that it has not become clogged with ingress that may obscure the
particulate sensing airflow.
The XD One has been designed with an inbuilt compliance check routine / test to allow for the infrequent
checking of device functionality against a selection of sized reference particulates.
The Compliance Check uses certified sample material that can be passed through the sensor to ensure
that all sensing and sizing parameters are functioning as intended. Reference material with a size spread
ranging from 0.35 to 40µm allows each sensing region to be populated with reference data during the
process.
To run the Compliance Check sequence, connect the XD One to the BreatheLITE software application,
position in the supplied compliance base and cover with the particulate dispersion hood before selecting
the automated test routine within the device maintenance menu.
The use of the compliance base and particulate dispersion hood allows for units to be isolated within a
known volume during testing as highlighted below.
