The comprehensive tester for transformer characteristics is a multifunctional field test instrument designed specifically for testing transformers: volt-ampere characteristics, transformation ratio, polarity, error curve, calculation of inflection points, and secondary side loop inspection. The transformer characteristic tester only needs to set the test voltage and current value during the experiment, and the device can automatically boost/boost, and quickly display the transformer's volt-ampere characteristic curve or transformation ratio, polarity and other experimental results, support Data storage and on-site printing not only saves the tedious labor of manual pressure adjustment, manual recording, and curve tracing, but also uploads the test data to the computer for editing, saving or printing through the USB interface.

In order to ensure the safe use of the transformer characteristic comprehensive tester, we must understand the operating precautions of the transformer characteristic tester before use.

1. Before putting the comprehensive tester of transformer characteristics into operation, check whether the tester has any visible damage.

2. Do not operate the tester in rainy or humid climates.

3. Do not operate the tester in the presence of explosive gas or steam.

4. Before putting the tester into operation, make sure that the vents, power switch and power socket are not blocked.

5. High voltage may be generated inside the transformer characteristic tester! Therefore, only qualified personnel are allowed to open the tester.

6. To prevent parasitic current or voltage, always connect the equipotential ground of the tester to the protective ground.

7. Make sure that the terminal of the test object connected to the tester does not carry any potential. In the test, the tester is the only power source for the test object.

8. When measuring the transformation ratio of the transformer, please ensure that the wiring is correct, otherwise life-threatening voltage may be generated inside the transformer, which may damage the transformer under test and the tester!

9. If the transformer characteristic tester or any additional device or accessory does not seem to work properly, please stop using it.
