Dräger Polytron 7000 Instructions For Use Manual page 47

Disposal of electrochemical sensors:
— Sensors must be disposed of as special waste.
Do not throw sensors into the fire – explosion hazard.
Do not open sensors forcibly – risk of caustic burns.
Note the relevant waste disposal regulations.
Further information can be obtained from the relevant local authority and
from appropriate waste disposal companies.
Sensor-diagnosis function
This function is active only if the Polytron 7000 is equipped with a sensor diag-
nosis dongle (Part No. 83 17 860).
— Extended sensor self-test function, taking such things as the temperature,
gas monitoring and remaining sensitivity into account.
— During normal operation, the sensor status is indicated by the sensor-diag-
nosis icon in the display:
The sensor is ready
The sensor is ready, but is approaching the end of its operating lifetime
The sensor is still ready, but it should be replaced as soon as possible
