      If the measuring value stays at "0" and does not change, ensure that the device has warmed up completely. Wait until the rdy mode is active before starting measurement. Also, make sure you press the measurement key in rdy mode. Check the connection between the probe and the analyzer, verifying the connection status between the probe and hose (gas inlet). Finally, inspect the probes, hoses, and filters for any blockages, as water-icing can occur, especially in the winter.
