Steps 2, 4: Connect zero gas / Connect span gas
During the transition to steps 2 or 4, the device changes to "Calibration" operating state.
Any assigned external solenoid valves for the zero gas or span gas are switched according
to the parameter assignment of the digital outputs.
If you do not use a gas connection controlled by external solenoid valves, the wizard
prompts you to connect the respective gas manually.
Setpoint and actual value (measured value) are displayed. As soon as the actual value
shows a stable behavior, apply this value. The wizard continues the process.
Steps 3, 5: Calculation
During steps 3 or 5, the current measured value is filtered first and then the calibration
factors are calculated. The actual value (measured value) then corresponds to the assigned
setpoint.
The processing progress is signaled by a bar graph. The remaining time until the end of the
calculation is output as well. The device automatically switches to the result window at the
end of the calculation.
Steps 4, 6: Information about the success of the calibration ("Result")
The wizard lists the results of the calibration in the result window and makes a logbook entry
in the background. This logbook entry captures the calibration data as well as the
corresponding result status (successful / not successful).
Exiting the wizard
When you exit the wizard after a calibration, the external solenoid valve is switched and the
measuring chamber is once again purged with sample gas. The device stays in "Calibration"
operating state for the assigned duration of the sample gas purging time.
The device switches back to "Measurement" operating state after expiration of the sample
gas purging time.
