4 Periodic Auto-zero Calibration
Sauermann recommends performing a fresh auto-zero calibration cycle approximately every
30 to 60 minutes of testing with the Si-CA 8500. This auto-zero calibration is performed
by simply disconnecting the hoses from the analyzer, and then turning the unit OFF & then
back ON.
Upon turning the analyzer back ON, the 180 second auto-zero calibration cycle and
condensate drain will initiate. After this has been completed, you can put the probe back
into the stack and then continue your tests. This procedure will help optimize the stability
and accuracy of your measurements over time.
5 Purging
When shutting the analyzer down after the testing is completed, it is recommended to
purge the analyzer with clean air for a few minutes with the hoses connected and then
at least another 10 minutes with hoses disconnected before completely turning off the
analyzer. This procedure will allow the analyzer to purge any toxic gases and help to
better protect the sensors and lengthen the sensor lives.
6 Periodic Filter Replacement
The Si-CA 8500 has two internal filters that are part of the flue gas sample conditioning
system that help maintain the performance of the flue gas sample while also protecting
the pump, sensors, and other internal components of the analyzer. The Line Filter
(#Si-CA8500 Line Filter) is designed to remove ash, dust, and particulate matter present
in the flue gas sample. The Condensation Filter (#Si-CA8500 Cond Filter) is designed to
remove any residual moisture that was not already removed by the condensate removal
pump. Both filters should be periodically examined and replaced as needed. Turn the
analyzer off when inspecting and/or replacing filters.
The Line Filter should be replaced
if it begins to accumulate excessive
particulate matter on its outer
surface, if the filter begins to show
signs of cracks in the filter, or if
the filter gets wet. This filter can
be easily replaced by accessing the
window on the face of the analyzer
as shown in the following photo:
The condensation filter is typically replaced much less frequently than the line filter and
should be replaced if it becomes saturated with water. This filter is accessed by opening
up the analyzer. More details can be found in the Maintenance section (Chapter 12) of
the complete Si-CA 8500 user manual.
7 Calibration
The Sauermann factory recommendation for recalibration of the Si-CA 8500 analyzer
is at least one time each year. This can be done at the Sauermann factory or another
calibration laboratory that has the proper gas bottles and setup to perform the
calibration. The calibration procedure and details are published in "Calibration" section
(Chapter 10) of the Si-CA 8500 user manual.
