Notes:

1. For personal and equipment safety, please read the instruction manual carefully before use and strictly follow the requirements for standardized operation.

2. Please ground the instrument reliably before the experiment.

3. This tester is an offline testing device for transformers. When conducting various tests on transformers, please be sure to disconnect the connecting wires on each terminal of the transformer.

4. During CT polarity test, the secondary winding that is not being tested should be short circuited.

5. When conducting PT volt ampere characteristic tests, the zero terminal of the primary winding should be grounded.

6. During the volt ampere characteristic experiment, press the controller and the tester will maintain the current voltage output for testing purposes. Press the controller again to end the experiment.

7. When conducting CT ratio experiments, if a large current causes the terminal to overheat, wait for the terminal temperature to decrease before unscrewing the connection again.
