nVision Operation Manual
Tare
Using the Tare function improves your dierential measurement uncertainty signicantly if used properly. The Tare function equalizes (normalizes) the nVi-
sion’s two modules at a non-ambient datum. The Tare reading displays the same units as the main ΔP or ΔT reading.
If y
ou apply the same static line pressure, temperature, or resistance signal to both sensors simultaneously, you should have a dierential reading of zero. Due
to the allowable error tolerance for each module, the reading may not be zero. The Tare function allows you to normalize both readings so that the dierential
reading is zero. This gives you a more accurate dierential reading than if this process were not completed.
Note: Tare should be reestablished every time your measurement conditions change, including vent condition. For instance if your ΔP reading has 8 inH20 of
Tare at 1500 psi static, when you return to vent condition this 8 inH20 of Tare will remain in place on your ΔP reading until cleared with the Tare button.
To Tare:
1 Use the (next) button to select the Dierential Mode Numerical Screen.
2 Press the
(zero) button until the display ashes dashed lines (- - - - -).
3 To clear the Tare value in the Dierential Mode, hold the button for 3 seconds until the main display readings change from (- - - - -) to (- - -).
