This measuring range has to be forwarded to the network analyzer. The box is preset for the 20A measuring range of the mini current clamps. All values deviating from this ratio have to be corrected with the conversion factor of the measuring device. For the 200 A measuring range, adjust the factor x10 in the network analyzer. |
