Program for Setting up the EC Channel

This software ensures the following:

  • Rapid set up of all EC channel parameters: EC probe frequency, generator output voltage, gain, filters, threshold level type, encoder, etc.
  • Four independent threshold levels for automated defect triggering (ALARM) for each displayed area;
  • Saving the testing setups into the PC or tablet`s memory;
  • Estimating the defect depth and length;
  • Channels mix.
