    Test setup verification
    Tim Hardin and Ray Rautenstrauch Recorded: Mar 25 2015 33 mins
    Sensor setup verification provides confidence in sensor performance and measurement chain installations, before running expensive or unrepeatable tests.

    A wide variety of techniques make it possible to verify sensor performance, connector and cabling integrity, signal conditioning, and data acquisition, or to identify problems along the measurement chain and make adjustments in the field.

    Meggitt experts Tim Hardin and Ray Rautenstrauch teach you about techniques and tools to simplify troubleshooting, verification, and system checks for vibration and pressure test systems which incorporate a variety of sensors.
