The Associated Research 7650 HypotULTRA III is a 5 kVAC / 5kVDC Hipot tester with a built-in Insulation Resistance and Continuity Tester. It can perform a low current continuity test simultaneously with the Hipot test, or use the separate continuity test mode to perform an independent continuity test. In this mode, the range is adjustable from 0.01 to 10 ohms. In addition, point-to-point continuity test can be run through the optional built-in scanner. The AR 7650 has up to 30mA of current is available in AC Hipot mode and 10 mA in DC Hipot mode with resolutions of 1 microamps in AC and 0.1 microamps in DC. The Insulation Resistance measurement range of the HypotULTRA III allows for measurements up to 50 Gigohms. It has an enhanced graphic LCD display with analog bar graph for monitoring test results.
