Thread: Pressure Sensor Setup Issue

  1. #1

    Default Pressure Sensor Setup Issue

    I'm having an issue setting up a custom pressure sensor. When I unplug the sensor completely I'm still getting a pressure reading in the Holley. I would think when nothing is connected it would read 0. When I enter the scaling per the manufacturer documents, Honeywell, it reads 10 psi with no pressure on it. Slightly confused here.

    0V usually does not = zero pressure, so it'll read something when the sensor is unplugged. Adjust your scale to read zero with no pressure. The manufacturers scale must be incorrect.
