Interval
After detection of a flaw, subsequent flaws detected within this time period (or within the length) will
be ignored (subsequent flaws are effectively counted as part of the first flaw).
Measurement avg
Set the time window over which diameter measurements are averaged to generate the “Measurement
Diameter”.
Reference avg
Set the time window over which diameter measurements are averaged to generate the “Reference
Diameter”.
A flaw is detected if the above “Measurement Diameter” deviates from this “Reference Diameter” by
more than the preset upper or lower SMFD flaw limits.
Flaws are detected when the “Measurement Diameter” deviates from the “Reference Diameter” by
more than the preset upper or lower SMFD flaw limits.
The “Measurement Average Time” should be set to smooth out any short duration noise on the
measurement; it may be left at its default value of 1ms unless measurement noise is large.
The “Reference Average Time” should be set to approximately 100 times the time duration of the
longest expected flaw.
If the “Reference Average Time” is set to too short a duration (i.e. close to the time duration of the
flaws), then the flaws will significantly affect the value of the “Reference Diameter” and may result in
the detection of false flaws.
If the gauge has just been powered on or a cable has just been inserted into the empty optical gate,
then the calculated “Reference Diameter” will only be valid after the “Reference Average Time” has
