3.1.2 Auto Trigger Mode/Manual Trigger Mode
The Locator probe can be used in either Auto Trigger mode or Manual Trigger mode.
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). This
mode can be used to determine the approximate noise floor of the measurement and to get an
approximate overview of the current PD activity.
To set the Locator into Auto Trigger mode, press the Auto Trigger button in the bottom centre of
the screen. If the button contains the following text "Manual trigger" the unit is currently in Auto
Trigger Mode.
In Manual Trigger mode, the trigger levels are manually controlled using either the Locator probe or
UltraTEV Plus buttons. Manual Trigger mode gives the user more control meaning the user can
2
adjust the trigger levels as the situation requires, allowing more accurate measurements to be taken.
To set the Locator probe into Manual Trigger mode, press the Manual Trigger button in the bottom
centre of the screen. If the button contains the following text "Auto Trigger" then the unit is already
in Manual Trigger mode.
You can also set the Locator probe into Manual Trigger mode by pressing the Level button on the
Locator probe, or the level button's on the UltraTEV Plus² screen.
