At the end of a Passing test sequence, the resistance of the EUT from Line to Neutral is measured. The meter on the HT-series displays the tolerance of the measured value (percentage above or below nominal) to an accuracy of 0.5%. Pressing a button on the HT-series tester causes the front-panel meter to display actual resistance (customer to specify tolerance and range). Separate LED indicators on the front panel of the HT-Series tester indicate when the measured value is above or below customer-specified values. This option is useful when testing products with resistive elements, such as heaters, ovens, or soldering irons.

If a failure is encountered during the hipot test sequence, the test is terminated as usual and no run time test is conducted.
