4.2 Operating modes
The device can be used in two different modes:
z > see chapter 5
Measurement
Adjustment z > see chapter 6
4.3 Measuring range
The device operates with a single measuring range, but two different units of measurement (parts per
million [ppm], percent by volume [vol.%]). The device automatically switches between the different
units of measurement.
Conversion: 10,000 ppm = 1 vol.%
