d) Setting Altitude (Altitude Compensation)
To receive correct values from your measurements, the altitude at the operating site of the
CO
CO
2
meter must be set. The setting uses altitude meters referring to sea level (NN = sea
level).
Proceed as follows:
• Briefly press the „MODE“ button repeatedly (from the normal operating mode) until
„ALTI“ flashes on the display.
• Briefly press the button „ENTER“; the medium display line shows the altitude display and
the altitude unit „m“ (meter) flashes.
• Set the altitude with the arrows „“ and „“.
• Briefly press the button „ENTER“ to save the setting.
e) Setting the Carbon Dioxide Normal Value in the Outside Area
The carbon dioxide normal value is required as a reference value to calculate the
ventilation rate („VENT RATE“) (also see chapter 9 i). The pre-set reference value is the
generally applicable value of 400ppm (average value of CO
ventilation rate („VENT RATE“) (also see chapter 9 i). The pre-set reference value is the
generally applicable value of 400ppm (average value of CO
2
concentration in the
atmosphere).
To change the normal value, proceed as follows:
• Briefly press the „MODE“ button repeatedly (from the normal operating mode) until
„OUTSIDE“ flashes on the display.
• Briefly press the button „ENTER“; the medium display line shows the reference value
(factory setting 400ppm).
• Set the reference value with the arrows „“ and „“.
• Briefly press the button „ENTER“ to save the setting.
