    OMP40-2 installation guide Trigger Logic™ All OMP40-2 settings are configured using the Trigger Logic™ technique. Trigger Logic™ (see Section 4 - Trigger Logic™) is a method that allows the user to view and select all available mode settings in order to customise a probe to suit a specific application.

  • Page 11: Modes Of Operation

    Note: This method is required when operating a twin probe system with an OMI-2T. After being switched on, the OMP40-2 must be on for 1 second minimum before being switched off. Timer off (time out) Time out will occur (12, 33 or 134 seconds) after the last probe trigger or reseat.
