It also measures insulation voltage across switch terminals, connector pins, and transformer windings.\u003c\/p\u003e\n\u003ch4\u003eQ: Does the tester have built-in safety features for high-voltage operation?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The unit features an 80 °C over-temperature protection circuit that activates a blue indicator light and halts operation to protect both the tester and the component under test. A low-battery alert also triggers when the lithium cell drops below 3.3 V, preventing inaccurate readings due to insufficient power.\u003c\/p\u003e\n\u003ch4\u003eQ: How is the tester charged and how long does it take?\u003c\/h4\u003e\n\u003cp\u003eA: The tester charges via a standard USB Type-C port using any 5 V\/1 A smartphone charger (not included). The built-in 700 mAh lithium battery charges at 550 mA; a red indicator light shows charging in progress, switching to green when fully charged.\u003c\/p\u003e\n\u003ch4\u003eQ: What is the output voltage accuracy and resolution?\u003c\/h4\u003e\n\u003cp\u003eA: The display accuracy is 0.3%. Voltmeter resolution is 0.1 V for readings at or below 100 V, and 1 V for readings above 100 V. The output voltage error is ±50 V, so at maximum output the actual range is approximately 3,650 V to 3,750 V.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
