To calibrate analyzer modules with simplified calibration procedures:
• Caldos27 with single-point calibration
• Magnos206 with single-point calibration
• Limas11 with calibration cells
• Uras26 with calibration cells
• Oxygen Sensor
The external solenoid is controlled via a digital output on the electronics module
(Digital output DO4 on Digital I/O Module – "Status signals / Externally controlled
calibration" standard function block application).

To calibrate all analyzer modules with zero and span gas even without an integral
gas module.
The external solenoids are controlled via digital outputs on the electronics module
(Digital outputs DO1, DO2 and DO3 on Digital I/O Module – "Calibration control"
standard function block application).
