HTT-1R LomA, Function Checker, Ground (Pass 0.1 Fail 0.025 ohm) Leakage (Pass 4.232M, Fail 2.088M) Arcover 750V ± 400V.
The HTT-1R was designed to provide a fast, safe and reliable way to verify proper operation of Dielectric Withstand (hipot) and Ground Bond Testers between calibration cycles, using actual component values which mimic the product being tested. It provides a stringent periodic check of your production line hipot and ground bond testers as required by TUV and others. The HTT-1R functions like our successful HTT-1 tester, but goes a step further by providing component values as the test loads, instead of opens and shorts provided by the HTT-1.
By choosing one of our standard configurations conforming to your testing parameters (or custom parameters based on your requirements), the hipot and ground bond tester in use are checked by realistic component values which mimic the characteristics of your production items.
The HTT-1R verifies the result of the three failure modes encountered in production hipot and ground circuit testing (open ground, high leakage current, and dielectric breakdown) separately or in any combination to verify proper test equipment operation. A passing test can also be simulated.
The HTT-1R is designed to test up to 30A ground bond testers using these values to simulate actual operation. Connections to the Ground Bond Tester will add approximately 0.03Ω to these values.
