    CIRCUTOR's after-sales service. 2.- PRODUCT DESCRIPTION CVM-NET4+-MC is an instrument that measures and calculates the main electrical parameters of three-phase (balanced or unbalanced) and single-phase industrial power networks. It measures effective (RMS) values, using three alternating and neutral voltage inputs and can measure up to 4 circuits with three current inputs (through current transformers In / 0.250 A) .
  • Page 7: 3�- Device Installation

    The CVM-NET4+-MC device must be installed by authorised and qualified personnel. The power supply plug must be disconnected and measuring systems switched off before handling, al- tering the connections or replacing the device.

    RX: Time Out 4�4�2�- CONFIGURATION OF THE TRANSFORMATION RATIOS The CVM-NET4+-MC can perform indirect measurements (using voltage and current transformers). For this reason, it has an input table to set the voltage and current transformation ratio configuration. If the voltage measurement is performed directly, the ratio is 1/1.
