    Functions  Tare Using the Tare function improves your differential measurement uncertainty significantly 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 you apply the same static line pressure, temperature, or resistance signal to both sensors simultaneously, you should have a differential reading of zero.

    Modules  „ „ „ „ „ BAROMETRIC REFERENCE (BARO) MODULE INSTRUCTIONS Installation of the BARO module in the power bay allows you to convert your gauge pressure measurement to the absolute scale if so desired. You may also view the barometric reference reading directly on a dedicated numerical screen. When the BARO module is installed, it may also be disabled in CrystalControl to conserve battery power, however your nVision will not be able to display absolute readings unless it is active.

    Support  Support „ „ „ „ „ TROUBLESHOOTING The nVision is a very high performance reference recorder. Due to the high resolution of this product, you may observe conditions that appear to be defects in the product, but are in fact a result of being able to read and measure pressure to a degree not possible with other instruments. Noisy or unstable reading when used with fluids When calibrating or comparing the indicated pressure from an nVision against a hydraulic deadweight tester or piston gauge, the reading on the nVision may appear unstable—the least significant digit jumps up and down several counts.
