AVERAGING MODE
Averaging mode reports the average reading during the recorded run. If this screen is enabled, data displayed here represents the average of all past data
points, over the duration of a recording. The start date and time, duration of the recorded run, and the live reading are displayed.
nVision calculates averages as follows:
r
1
+ r
2
+ r
3
... + r
n
n
r
n = current reading
n = total number of readings

DIFFERENTIAL MODE
The nVision automatically displays numerical and graphical differential screens if two similar module types are installed. ΔP becomes available if your nVision
is populated with two PM modules. ΔT becomes available if your nVision is populated with two RTD100 modules.
In the case of the pressure modules (PM), this mode does not require them to be the same full scale range.
!
WARNING: Two MA20 modules cannot be installed at once. This configuration may permanently damage your nVision.
In Differential Mode the ΔP or ΔT represents a filtered reading of the upper module – lower module + tare reading.
Filtered live reading of upper module
Filtered live reading of lower module
Tare value equalizes the upper and lower modules
Differential Mode
The units selected for this view are independent of the units selected for the other screens such as the Numerical or Graphical views. Data viewed in the
Graphical screens will represent the data acquired from either module and not represent the specialized view of the Differential Mode.
Note: To change the displayed units on any Differential Display, see the Units section.
