• The FSR is the current FSR, calculated upon a period of 200ms.
• The AccumFSR shows either the accumulated FSR of the current accumulation,
or if no accumulation is running, the results of the most recent accumulation.
This enables you to monitor real-time FSR behavior as you do things such as to
manually adjust the sampling point, to add errors, or to make adjustments to your
device.
Click this button to toggle between FSR or AccumFSR results.
This area displays the actual filler symbol error count or cumulative filler symbol
