Usage Guide

1Connect this device to the tested current transformer.K2With the validatorTxBetween.

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

Note:Secondary loads of some current transformers are represented by resistance.,Ω.The load of a current transformer load box is generally expressed in terms of capacity.VA.The 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, the total resistance value of the two connection lines at the secondary terminal of the transformer must be connected to the load box.0.06If a secondary link-up verification instrument is used, the load caused by the secondary of the transformer should also be taken into account to ensure accuracy.
