4.2 CO
2
sensor
Connect or remove the CO
2
sensor without rotating and only when the incubator is turned off. Remove
the CO
2
sensor before removing or replacing its filter cap. The Teflon filter of the CO
2
sensor prevents dirt
and humidity from intruding into the measuring cell. It is available as a spare part. Replace it whenever it
is damaged or soiled.
The accuracy of the indicated values of CO
2
depends on the ambient air pressure (approx.
0.08 vol.-% per 10 mbar / 0.15 psi ). In order to compensate this effect when measuring the
CO
2
concentration, the altitude of the installation site above sea level can be entered into the
controller (chap. 8.1).
The CO
2
sensor is temperature resistant up to a maximum temperature of 60 °C / 140°F.
CAUTION
Excess temperature.
Damage to the CO
2
sensor.
∅
Do NOT autoclave the CO
2
Sensor.
∅
Do NOT expose the CO
2
sensor to hot-air sterilization.
The CO
2
sensor head was especially adjusted for the specific chamber. To avoid confusion, an adhesive
label with a serial number is adhered to the sensor head. When exchanging the sensor, you must repeat
the CO
2
adjustment.
CAUTION
Different CO
2
sensor.
Invalid calibration.
∅
Do NOT change the CO
2
sensor head.
¾ Note down the serial number of the CO
2
sensor.
Avoid strong shocks when handling the CO
2
sensor.
CAUTION
Shocks of the CO
2
sensor.
Damage to the CO
2
sensor.
∅
Avoid strong shocks of the CO
2
sensor (by putting it down hard, or dropping).
4.2.1 Connecting the CO
2
sensor
Turn off the unit. Open the door of the inner chamber and plug the CO
2
sensor (4) without rotating into
the connection socket located in the upper part of the rear of the inner chamber.
The sensor must click in correctly and sit tightly in the connection socket.
CAUTION
Connecting or removing the CO
2
sensor during operation.
Damage to the CO
2
sensor.
∅
Connect or remove the CO
2
sensor only with the unit turned off.
