User's Guide

1Connect this device to the test current transformer.K2With the calibratorTxBetween.

2Adjust the load to the actual secondary load of the test current transformer.

Note:Secondary loads of some current transformers are represented by resistances.,Unit: Ω.The load of a current transformer burden box is generally expressed in terms of capacity.VA.Their conversion relationship is::

Capacity(VA)=Resistance Value(Ω)*Secondary Current(A)* Secondary Current(A)

（1Ensure proper grounding of this equipment.

Caution: To ensure the accuracy of the secondary load of the transformer, it is necessary to connect the secondary terminals of the transformer to the two connection lines of the load box, with a total resistance value of0.06If the secondary reconnection verification meter is used, the load caused by the secondary of the transformer should also be taken into account to ensure accuracy.
