Meaning Explanation
After calibration, verify that the displayed status is "auto." Oth-
erwise data may not be saved correctly or the device does
not start up automatically after a power failure.
An error is also indicated if the aerosol sensor is defective
and no PM values are being measured (all values = 0).
The Status log on the right side of the screen shows activities occurring
on the device, along with the date and time.
Meaning
Standard device operating mode
During calibration the data is labeled as c and not considered for the
evaluation.
The device is in idle mode and is not measuring any data.
The device is in "manual" mode.
The electronic oscilloscope, which can analyze single signals, is acti-
vated.
No measurements occur during this time.
The measured particle size distribution is invalid.
The concentration was so high that more than 10% of the values
were measured in coincidence, meaning that more than one particle
was in the detection volume at the same time.
