Configuring Multiple Channels - Fluke 2680A User Manual

Channel A or Channel B
Select from the configured channels in the instrument for difference functions.
You cannot select channels in another instrument.
Equation
Computed channel equations are described in Using Equations with Computed
Channels later in this chapter. See Appendix E for detailed information.
Average Channels
Select which channels you want to average. You can select any configured
channel on any module in the instrument as well as any configured computed
channels.
Factors (Mx + B)
Used to scale measurements with a slope-intercept linear equation. Mx + B
scaling multiplies a measurement by a multiplier (M) and then applies an
offset (B). For example, Mx+B scaling of 100x+50 applied to a measured
value of 1.15 would result in a reading of 100(1.15)+50=165.
Input or Scaled Range
You can enter the Input and Scaled range and press the Calculate M and B
from Ranges button to have Fluke DAQ calculate the M and B values.

Configuring Multiple Channels

You can change or set configurations using multiple selections in the TreeView
window. The screen that displays when a multiple selection is made has controls
that assume the values of the lowest selected node. Fluke DAQ considers the
lowest node the one that has the lowest number between the selected nodes. When
the other selected nodes have data that differ, the controls on the dialog assume a
different state. The table below lists the controls and their possible states:
