Automated Digital Hipot Testers for Electrical Safety Testing
A hipot tester, also called a dielectric withstand tester, applies a high potential between isolated conductive parts to evaluate insulation integrity and determine whether a product withstands the specified test voltage without breakdown or unacceptable leakage.
The ED&D Millennium Series models provide single-button test initiation, visible and audible pass/fail indication, a safety-protected start switch, selectable automatic test timing, and a low-current ground continuity test function.
The ED&D Check-MATE HP provides daily functional verification of compatible ED&D hipot testers.
Technical note: products containing EMI filters may require DC hipot testing. Confirm the permitted test method and voltage with the applicable product safety standard.

Frequently Asked Questions
What does a hipot tester do?
A hipot tester applies a high voltage between isolated conductive parts to verify insulation integrity and confirm dielectric withstand capability without electrical breakdown.
What is the difference between the HP-1000 and HP-2000?
The HP-1000 is an automated AC digital hipot tester, while the HP-2000 is an AC/DC digital hipot tester that adds DC test capability for applications where AC-only testing is not ideal.
When should a lab use DC hipot testing instead of AC?
