    You can, for example, use a typical, often-used device under test as a reference, or use measurement equipment with a certified high accuracy. Should the test equipment fail, immediately contact OMICRON Support for calibration or repair. Do not try to use it anymore.
  • Page 19: Main Power Supply

    Operational limits in conjunction with a weak power supply input voltage In general, the maximum output power of the CMC 310 is limited by the power supply input voltage. If the power supply input voltage is less than 120 V , it is possible to supply the CMC 310 with 2 phases (L-L, for example with a NEMA 6 240 V U.S.
