Calibration
Troubleshooting
Problem Solution
No Reading at Controller • Check sensor calibration (see above)
• Check for amperage in monitored conductor (> 2.5A)
• Assure that sensor core mating surfaces are clean and that the core clamp is completely closed
Setpoint screw has no stops The setpoint screw has a slip-clutch at both ends of its travel to avoid damage. Twenty turns CCW will
reset the sensor to be most sensitive. Repeat calibration above.
Both LEDs are lit Setpoint screw is too far clockwise. See solution above.
