Appendix A Maintenance and Troubleshooting of this Device
The procedures stated in “Acquisition of index values under normal conditions” and “Clogging
simulation test” refer to the following parameters and process variables.
Pressure Frequency Index
Press Freq Index Max
Press Freq Index Min
Standard Deviation
Standard Deviation Max
Standard Deviation Min
The standard deviation values are not directly used to diagnose clogging, but it may be necessary to
refer to them during parameter adjustment. Therefore, it is recommended that they be collected at
the same time as the pressure frequency indexes.
