CEL-712 Microdust Pro Real-time Dust Monitor
29 Casella Measurement
Allow a few seconds for automatic ranging and for the reading to stabilise. If the
reading does not stabilise, squeeze the bulb five or six times and try again.
When the measurements stabilise during the clean-air purge, press the Yes soft
key to start the zero adjustment. A progress bar is displayed during the zero
adjustment and the screen will indicate whether the calibration is successful.
Press the Ok soft key to return to the main Calibration screen.
IMPORTANT
If the instrument cannot zero itself in the range 0 to 2.5 mg/m³, it displays a
‘Contamination Warning’ message and selects the 0 to 25 mg/m³ range. This then
becomes the Instruments lowest available range until the probe is cleaned. For
accuracy and stability, you should arrange for cleaning to be done by an approved
Casella Service centre.
After you have set the zero, make sure you fit the rubber cap on the probe’s
purge inlet.
