  • Page 7: Handling Instructions

    HANDLING INSTRUCTIONS The coil is fully inserted when the user feels the free-end of the coil engage with the internal click-in mechanism inside the ferrule. Visual indication that the coil mechanism is fully inserted is provided by the black coil marker situated near the end of the coil, as shown below.

  • Page 8: Safety And Pre-Use Checks

    When bending the flexible coil around a conductor, avoid tight bends and sharp edges that could damage the coil. The voltage rating is clearly labelled on the coil. For the CMC this is 10kV peak. Never use at voltages greater than this value. The removable silicone sleeve supplied with the coil provides additional mechanical protection.

  • Page 9: Power Options

    POWER OPTIONS The CMC can be powered by an external DC source or by one of two battery options. The battery option is displayed along with the model type on the serial number label and will state either standard non-rechargeable batteries [B] or rechargeable option [R] External Supply The CMC can be powered by an external DC supply.

  • Page 10: Switching On

    4. Re-energise the conductor. 5. Use the push-button to switch ON by pressing and releasing the button, and to turn OFF by depressing the button fully; the LED indicates that the CMC is ON when the LED is GREEN. After switch on the CMC may require a settling period of up to 2 minutes before providing an accurate measurement.

  • Page 11: Obtaining The Best Measurement

    SHADED AREA SENSITIVITY TO EXTERNAL CURRENTS AND VOLTAGES The sensitivity of the CMC to currents that are outside the closed loop of the Rogowski coil is very small, provided that the external currents are less than the current rating of the transducer or that such currents are relatively distant from the coil.

  • Page 12: Cleaning And Decontamination

    In the event of a defect where the transducer has not been misused the CWT should be returned to PEM with all freight charges to be paid by the customer. Correction shall be in the form of repair or replacement.
