Hipot testers are the opposite of continuity testers. These testers make sure current does not flow from one point to another on an electronic device even with extremely high voltage. A hipot tester checks for good isolation between circuit parts. Passing this test indicates you offer a product that is safe to use and meets superior performance standards.

Use a direct current hipot test, also called a dc hipot test, or an alternating current hipot test to assist in the location of stray wire strands, contaminants around the conductors and other conditions that might make a device unsafe or less productive. When purchasing a hipot tester you should:

1. Find the safest hipot test equipment that will suit your specific needs.

2. Sample hipot testers to ensure the hipot tester you buy works like you expected it to.

3. Purchase hipot test equipment from a supplier that offers training and product support.
