The status of the Virtual Measurement is shown in the block immediately above the trendlines. During normal operation, this box will remain gray and read ‘Normal’. This indicates that the virtual measurement is receiving valid inputs to calculate the inferred weight, and also that a valid scanner measurement of weight is available.
During this normal operation, while the scanner is on-sheet and measuring, the virtual measurement continuously correlates itself to the scanner measurements – to improve accuracy during the critical times when the scanner is unavailable.
If there is a lack of data for the online calculation, or the input signals are invalid, an error message such as “out of range” appears.
When the machine starts up, so do the input signals, and the virtual measurement can pull data to calculate the inferred weight. The status changes to “estimating”, turning a bright blue to draw attention.
This would be an indication that the QCS scanner is offline. It’s also when the Weight Virtual Measurement is most valuable, becoming the stand-in for the now missing physical measurement of weight.
