Error Filter (menu 6.6.3)

Here you can enter limits for reliability evaluation of flow measured values:
The appropriate error message will only appear when the proportion of bad measured values exceeds the
selected percentage value:
"uncertain": · Quality in measured value status is set to "uncertain" (uncertain, non specific")
· The "DIA_MEASUREMENT" diagnosis bit (DIAGNOSIS, chapter 4.1.3, page 17) is set
· Local display under "Device status": "Unreliable flow value"
"bad": · Quality in measured value status is set to "bad" (bad, sensor failure")
· The "DIA_MEASUREMENT" diagnosis bit (DIAGNOSIS, chapter 4.1.3) is set
· Local display under "Device status": "Measuring path error"
· The measured values for flow, sound velocity and ultrasonic amplitude are
set to 0 (related to measuring scale).
