In Auto Trigger mode, the Locator probe will automatically set the trigger levels to be slightly above the noise floor, meaning triggers are always present (unless the noise floor is below 0dB).
  • Page 13 EA Technology UltraTEV Locator Probe Operating Manual 2852-MANUL-V01.03.00 When in Manual Trigger mode, the level buttons on the UltraTEV Plus² screen can be used to control the trigger levels for each probe. 3.1.3 Level Buttons The Locator probe also has an automatic levelling function. This function determines the maximum trigger levels present and sets the trigger level to comfortably below this value.
