11.3.1 AutoCal for external mounting of the solenoid valves
Usually, solenoid valves that are not part of the analyzer are used for switching between
sample and test gas and for connecting zero and span gas. These solenoid valves are con-
trolled by the switching outputs of the analyzer.
When connecting the solenoid valves, observe the marking of the corresponding
sockets.
