The GFR-2 system can work with a wide variety of Sensors. Skymatic Controls can recommend an appropriate model. The trip range and the appropriate sensor (for which the relay was calibrated) are displayed on the label.

The final calibration will be completed in the following sequence:

  1. Turn the potentiometer clockwise
  2. Set the calibration current
  3. Turn the potentiometer counter-clockwise until the relay trips
