15.3 Cleaning labels
It is recommended to periodically clean the instrument with a damp cloth, to ensure the
instrument user interface and keypad is clean and legible.
15.4 Particulate entry/exit apertures
The particulate exit aperture is protected by a stainless-steel grille to minimise the ingress
of flora and fauna into the D1
+
device. It is recommended that the grille is checked and
cleaned during maintenance periods to ensure that it has not become clogged with ingress
that may obscure the particulate sensing airflow.
15.5 Compliance audit check
The D1
+
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 specific size spread allows each sensing region to be populated with reference
data during the process.
To run the compliance check sequence, connect the D1
+
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.
1. Insert the D1
+
into
the compliance dock.
2. Cover with particulate
dispersion hood.
3. Run BreatheLITE
compliance check.
