Setting Signal Polarity
Quick access:
Explorer tab > Set Up > New Specimen > Install Fixturing
Note:
Stop all tests before changing signal polarity.
Changing signal polarity requires the Change Polarity user privilege. If you do not have this privilege,
you will be prompted to log in with a role and password that has the Change Polarity user privilege.
Setting signal polarity allows you to specify which direction of the sensor shows positive values and which
shows negative values. Changing signal polarity is most commonly done when switching between a tension
test and a compression test. The polarity setting for the station persists until you change it, even if you
close and re-open the MP application.
