1. When high measurement accuracy is required, it is best to use an internal transformer for measurement. When connecting a current transformer, it is necessary to strictly ensure that the secondary side of the current transformer is not open circuit.
2. Clamp type transformers are high-precision measuring transformers. It is important to handle them with care to avoid collision or damage, otherwise it may affect the testing accuracy. The incision surface of the clamp watch should be kept clean and smooth, without contaminating other debris, to ensure good closure of the clamp watch.
3. Before starting the test, please enter the correct setting parameters, otherwise it may cause deviation or errors in the data results.
4. When using a clamp shaped watch to clamp an aluminum bar, be sure not to let the iron core of the clamp shaped watch cut into the aluminum bar, otherwise it may cause danger and damage the clamp shaped watch and instrument.
