Matters needing attention and safety measures when using transformer DC resistance tester

1. Read this manual carefully before using the transformer DC resistance tester.

2. The operator of the transformer DC resistance tester should have general electrical knowledge.

3. When using the transformer DC resistance tester, avoid rain, corrosive gas, excessive dust, high temperature, direct sunlight and other places.

4. The transformer DC resistance tester should avoid severe vibration.

5. After the test, be sure to wait for the discharge alarm to stop before turning off the power and remove the test wire.

6. When measuring the no-load voltage-regulating transformer, you must wait for the discharge indication alarm sound to stop before switching gears.

7. During the test, it is forbidden to move the test clip and power supply line.

Precautions

1. For the no-load voltage regulating winding, it is not allowed to switch the no-load tap changer during the test or when the power is not discharged.

2. For the test object of inductive resistance, it is not allowed to remove the test wire when the battery is not discharged (when the buzzer is sounding) to avoid electric shock.

, During the test, if the external AC220V is suddenly cut off, the transformer DC resistance tester will start to discharge automatically. At this time, it is not allowed to remove the test wire immediately, and the wire can be removed after 5 minutes.
