3. Finish setting up the dynamic proximity probe measurement by setting
Data Type to Magnitude and Units to mils or um.
You can use a Filter if desired.
Follow these steps to setup a Static (DC) component or gap.
1. Set up a displacement transducer in the Transducer Calibration dialog box
with Input type set to DC Coupled and Units set to mils or um.
Make sure you enter the Calibration value that converts the voltage to a
displacement. If you are using the DC Input Module to remove the AC
component and attenuate the signal be a factor of 2.5, then you must
divide your transducer's calibration by 2.5.
2. Set up a Collection Specification with Transducer set to the DC
displacement and Signal detection set to RMS.
3. Finish setting up the dynamic proximity probe measurement by setting
Data Type to Magnitude and Units to mils or um.
You must set the Filter to None because any type of high pass filtering
removes the DC component.
