particle measuring device BQ30
Carrying out a measurement
Info
Please note that moving from a cold area to a warm
area can lead to condensation forming on the device's
circuit board. This physical and unavoidable effect can
falsify the measurement. In this case, the display
shows either no measured values or they are incorrect.
Wait a few minutes until the device has become
adjusted to the changed conditions before carrying out
a measurement.
Once you have switched the device on, it automatically
performs the measurement. You can tell whether the device is
currently performing a measurement from the indicated
measurement status (15) on the display.
In addition to the displayed measurement results an indicator
scale for particle contamination (11) further helps you in judging
the measured results (see chapter Information about the device
for more details). When measuring the CO
2
concentration the
device displays the measured result in one of the following
colours:
Air quality
