For the calibration of the sensor cartridge, you need a PC tool or the MSC-06-STL Service Tool. There is an automatic
routine in the calibration menu of the Service Tool STL.
As long as the calibration menu is open and the sensor is gassed with test gas, the alarm release is blocked.
Prior to calibration the sensor must be connected continuously to the power supply for stabilization for a running-in
period.
This running-in period of some sensors can be taken from the following table:
Sensor/Gas type

CO2

Combustible gases

Project protection
To prevent access to the sensitive calibration data by third parties, every customer receives his own internal project key.
All projects of the customer are delivered with this key. The key is also stored in each MSC-06-STL Tool that the
respective customer buys.
If the keys do not match, the following message appears
NO ACCESS AUTHORIZATION
The calibration is documented in the User Manual of the Service Tool.
