CIRCUTOR's after-sales service. 2.- PRODUCT DESCRIPTION The CVM-C11 device measures, calculates and displays the main electrical parameters of the following networks: single-phase, two-phase, with and without neutral, balanced three-phase, with ARON meas- urements or unbalanced. The measurement will be taken in RMS with the three AC voltage inputs and four current inputs.
The CVM-C11 device must be installed by authorised and qualified staff. The power supply plug must be disconnected and measuring systems switched off before handling, al- tering the connections or replacing the device.
The flexibility of the sensor allows it to measure an alternating current irrespective of the position of the conductor. CIRCUTOR has 1 Rogowski sensor model that can be used with the CVM-C11-FLEX-IN-485-ICT2: MFC- FLEX. Note: For more information, consult the corresponding sensor guide.
