New Array Variables for Channel Calculations


In Maintenance Release 2.9.8.24299-0329, new array variables were added to improve channel calculations for measurement points, uncertainty, and custom fields:

  • #ChMean – Mean result for all channels in the measurement point.
  • #ChStdDeviation – Standard deviation for all channels.
  • #ChError – Error for all channels.
  • #ChDelta – Delta for all channels.
  • #ChRange – Range for all channels.
  • #ChHysteresis – Hysteresis for all channels.
  • #ChUncertainty – Uncertainty for all channels.


The updates in Qualer’s Maintenance Release benefit service providers by enhancing the accuracy and efficiency of channel calculations, improving measurement capabilities for multi-channel instruments, and offering greater customization through custom fields.  



Example Usage:

  • AVG(#ChMean[]) for average mean.
  • AVG(#ChError[]) for average error.
  • MAX(#ChDelta[]) for maximum delta.
  • MAX(#ChRange[]) for maximum range.
  • MAX(#ChUncertainty[]) for maximum uncertainty.
