Unit UT501B Insulation Resistance Tester is an insulation resistance tester model from the UNI-T UT500 series. It has a 2000-count display. Measurement functions: AC voltage (30 V – 600 V), insulation resistance, low resistance (continuity) (0.01 Ω – 200 Ω (approx. 5.0 V / >200 mA)). Test Voltages: 250 V / 500 V / 1000 V · output tolerance 0% – 10%. Short-circuit current <2 mA. Other features: PI (polarization index), secondary test voltage display, 10 MΩ internal resistance test, auto range, low battery indicator, backlight, visual alarm, audible alarm, high voltage indicator, overload indicator, automatic discharge, DAR (dielectric absorption ratio, 60 s / 15 s and 60 s / 30 s). Power source: 6 × 1.5 V battery (LR6). Box contents: batteries, test probes, alligator clips, hanging strap.
