Setup and Installation
Follow these steps for proper installation of your split core current sensor. Ensure all power is disconnected from the circuit before proceeding.
- Safety First: Always disconnect power to the circuit where the sensor will be installed. Verify with a voltage tester.
- Open the Sensor: Gently open the split core sensor by releasing the latch mechanism.
- Position the Conductor: Place the primary conductor (the wire carrying the current to be measured) through the opening of the sensor. Ensure the conductor passes cleanly through the center of the core.
- Close the Sensor: Carefully close the two halves of the sensor until the latch mechanism securely clicks into place. Ensure there are no gaps between the core halves.
- Connect Output Wires: Connect the red and black lead wires from the sensor to your measurement device (e.g., multimeter, data logger, energy meter). The sensor typically has S1 and S2 terminals for connection. Refer to your measurement device's manual for correct wiring.
- Verify Connections: Double-check all connections to ensure they are secure and correctly polarized if applicable.
- Restore Power: Once installation is complete and verified, restore power to the circuit.

Operating Instructions
The OPCT24AL sensor converts the primary alternating current into a scaled output current or voltage, depending on the specific model variant.
- Current Measurement: The sensor provides an output proportional to the AC current flowing through the primary conductor.
- Output Interpretation: The output (e.g., 26.6mA, 333mV, 100mA) needs to be interpreted by a compatible measurement device. Refer to the sensor's current ratio (e.g., 2000/1) to calculate the primary current from the measured output.
- Directionality: While split core CTs are generally not strictly directional for magnitude measurement, consistent orientation of the primary conductor through the core (e.g., always entering P1 and exiting P2 if marked) can be beneficial for phase-sensitive applications.
- Overload: Avoid exceeding the maximum rated primary current of the sensor to prevent damage and ensure accurate readings.
Maintenance
The CLXDKLKEQ OPCT24AL current sensor is designed for minimal maintenance.
- Cleaning: Keep the sensor clean and free from dust and debris. Use a dry, soft cloth for cleaning. Do not use abrasive cleaners or solvents.
- Inspection: Periodically inspect the sensor for any signs of physical damage, such as cracks in the housing or frayed lead wires. Ensure the latch mechanism operates smoothly and securely.
- Environmental Conditions: Ensure the sensor is operated within its specified environmental conditions (temperature, humidity) to maintain performance and longevity.
- Core Integrity: The mating surfaces of the split core should be kept clean and free of foreign material to ensure proper closure and accurate readings.
