The gas sensor must be in the "normal" state for a calibration to be performed� The
second line shows the current CO
line is a button that facilitates setting the target or actual concentration� Leave this
at zero if pure nitrogen is being used for calibration�
The fourth line is the [Base Cal Now] button� This causes the sensor to execute a
calibration function to make its output match the target concentration� Calibration
takes about 15 seconds� Another calibration cannot be performed without leaving
and returning to this screen�

This screen is available only on models with the optional temperature humidity
sensor and after the level 2 password has been entered� This feature allows the
monitor to be installed in an area that is known to be characteristically cooler or
warmer than the rest of the space (e�g�, near a photocopier)� This requires that a
desired value ("target temperature") be entered�
The monitor is precalibrated so calibration is unnecessary�
Press the "Target" button to enter the target temperature through the numeric
keyboard, within a range from 32 to 122°F (0 to 50°C)� The default value is 68°F
ü
(20°C)� Press [ ] to return to the Cal Temperature menu, then press the "Calibrate
Offset" button� The monitor will then calculate the difference between the room
temperature and the desired temperature� This difference is the offset� When the
calibration has been completed, "Calibration Done" will be displayed� Press [X] to
