The meter display shows the detected concentration. The resolution
of the display changes with the magnitude of the reading. A reading
of 0 to 99.9 will be displayed with a resolution of 0.1 ppm or mg/m³.
A reading greater than 99.9 will be shown with a resolution of 1 ppm
or mg/m³. The meter will display concentrations up to 2000 ppm or
2000 mg/m³.
The status display is used to display the instrument status, date, time,
units and active soft keys.
