Range | Nominal Resistance( Ω ) | Initial Deviation[1] ( ± μΩ/Ω ) |
Year Stability ( ± μΩ/Ω ) |

Note[1]:The initial deviation refers to the deviation between the measured resistance value and the nominal resistance value after the rated DC current is applied for 10 minutes under the calibration temperature environment; [2]:The initial deviation of the DC resistance has included the power factor influence error under the nominal current. When measuring other non-nominal current values, additional measurement uncertainty should be introduced. The calculation formula is: |
Range | Primary Nominal Current ( A ) |
Secondary Nominal Voltage ( V ) |
AC/DC Difference[3] ( ppm ) | Maximum Working Current( A ) | Instant Current ( A, <5 s ) |

20 A | 20 | 1 | 20 | 30 | 100 | 22 | 50 |
Note[3]:The measured value of AC current should be calculated according to the following formula, and the unit of AC/ DC difference is ppm: |
