Now that we have zero-gas flushed through the validation cell and baseline
subtraction is turned on, the analyzer will record the zero measurement.
The zero measurement will now be available for reading over Modbus.
There is no involvement from the HMI in this step and the Laser 3 Plus will
automatically proceed to the next step once the zero measurement has been
recorded.
The analyzer will now ask for the span-gas to be turned on and the zero-gas to be
turned off.
The process is exactly the same as previously described for turning on the zero-gas.
As soon as it has asked for span-gas to be turned on, the Laser 3 Plus will proceed
to the next step which is span-gas flush.
The Laser 3 Plus will now wait for the span-gas to flush through the validation cell.
The process is exactly the same as for the zero-gas flush in step 6.
There is no involvement from the HMI in this step and the Laser 3 Plus will
automatically proceed to the next step once span-gas flush has been completed.
Once we have completed the span-gas flush, we again have to wait for the
measurement to stabilize. The measurement, once it has stabilized should be the
validation gas concentration plus or minus a tolerance.
The process is exactly the same as for step 4.
There is no involvement from the HMI in this step and the Laser 3 Plus will
automatically proceed to the next step once span measurement stabilization has
been completed.
