Test Gas Supply Control for Automatic Calibration
Test Gas Supply
The test gas supply for automatic calibration can be started by means of the gas
module’s integral solenoid valves or via external solenoid valves.
Depending on the gas supply circuit and the number of analyzer modules installed
there are several test gas layout possibilities (see Figures 8-A-2 to 8-A-6):
1 Analyzer Module,
Gas Module Installed
with 1 Solenoid
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
