After receiving the unit, please check the following points:(a) Does this device correspond to your order specifications?(b) Check if any damage was done during the shipment process.(c) Verify that it includes the correct instruction manual.The manual you hold in your hands contains information and warningsabout the CVM-LC that the user should respect in order to guaranteea proper operation of all the instrument functions and keep its safetyconditions. Before powering the instrument for the first time, verify following points:(a) Power supply: see rear part of your CVM-LC Standard : 230 V a.c. Single-phase, Frequency: 50 ... 60 Hz SDC Model : 24 .... 120 V d.c. Other supply voltages, on request.(b) Maximum measuring voltage: Standard : 300 V a.c. phase-neutral / 520 V a.c. between phases Other models: on request CVM-LC - measuring 110V: 110 V a.c. phase-to-neutral /190 V a.c. phase-to-phase CVM-LC - measuring 500V: 500 V a.c. phase-to-neutral /866 V a.c. phase-to-phase (c) Maximum measurable current: Current transformer of In / 5 A a.c. ----- Supply network analyzer CVM-LC ------ User's manual --- Page No. 3 2.- MAIN FEATURES The CVM-LC power meter is a programmable measuring instrument, offeringseveral operation possibilities selectable in its SET-UP option. Before powersupplying the instrument, read the CONNECTIONS and SET-UP sections andchoose the most suitable operation mode for getting your desired data. CVM-LC L1L2L3 The CVM-LC is an instrument which measures, calculates and displays all themain electrical parameters at any electrical network (balanced or not). Themeasuring is true RMS value, through three a.c. voltage inputs and three a.c. currentinputs (from Current Transformers .../ 5A).
