Sync Sensor Arming Threshold

Sync Sensor Arming Threshold

Arming thresholds for digital signals (including crank and sync sensors) describe the level in which the voltage level must go above before the signal can be valid.  Regardless of signal (magnetic, or digital), the threshold voltage level must be reached before the signal can be considered valid.  

** The threshold value does not mean this is the value in which the ECU “triggers”.

Note: This option is available on ALL trigger types. 

On any square wave 0- 5V signal it is recommend to set the arming threshold to 2.0V flat across the table.

** Use the scope function within the Emtron to validate the voltage threshold to be used.  See Scope - Uses of Scope
