Precision Flexible AC Current Probes SymmProFlex® FCP 3121 and FCP 3321 are current probes based on Rogowski principle designed to measure alternating current up to 3000 A, 6000 A, 12000 A or more. Current Probes SymmProFlex® FCP 3121 (single-phase) and FCP 3321 (three-phase) are designed for usage with measuring equipment which is able to use I2C communication for accessing software calibration parameters stored in probe’s internal EEPROM memory.
