Every nutrient is zero, or all values are the same — usually a disconnected fiber cable.

  1. Check the fiber optic cable (Part C). Look for disconnection or kinks.
  2. Fully reseat the fiber optic cable at the 45° connector at the probe (Part A).
  3. Confirm the probe power source (Part B) is connected to the probe handle and plugged into the power outlet, and that the probe tip light is visible.
  4. Restart the software, recalibrate, and scan a fresh leaf.
