The HS-2 also features an audible alarm that gives warnings when the CO2 value exceeds the maximum (see P1.0 for Alarm setup). The HS-2 will beep (80 db) when the CO2 value exceeds the set-value and can be switched off by pressing a random key, except “SET”. Restart the meter if the beeping does not stop. - Page 5 WARNING: Do NOT calibrate the HS-2 in an area of which the CO2 value is unknown. Otherwise, the meter will be calibrated automatically as 400ppm, which will lead to inaccurate measurements. It is advised to conduct a manual calibration in outdoor air when the weather is sunny.
