5 Calibration
The service tool STL06 or PCE06 Software are available for convenient on-site calibration. See description of
Service Tool STL06 or PCE06 Software.
There is also the possibility to exchange the SC against a calibrated SC on site. The used SC can then be
calibrated directly in the office or at the MSR_E Calibration Service and then reused again.
Prior to calibration the Sensor Cartridge must be supplied with power voltage without
interruption for warm-up and stabilisation. The run-in time depends on the sensor element and is
shown in the following table:

Table Calibration
Please observe proper handling procedures for compressed gas and test gas bottles (regulations
TRGS 220)!
Test gas can be toxic, so never inhale it!
Symptoms: Dizziness, headache and nausea.
Procedure if exposed: Remove victim to fresh air at once, seek medical attention.
5.1 Calibration Work
Prior to calibration you have to activate the mode “Special Mode” at the basic device, only then the
calibration menu is enabled. During the special mode the basic device doesn’t issue alerts.
• Connect calibration adapter carefully to the sensor cartridge.
• Connect calibration tool you want to use to the PCB.
• Select the Sensor Cartridge to be calibrated by selecting the gas type.
