Features: High-Definition LCD Display: The tester features a high-definition LCD display with a built-in backlight, allowing for easy reading of measurements in both brightly lit and dark environments and ensuring clear visibility of values at all times. Multi-Voltage Level Design: Unlike traditional hand-cranked meters, this digital insulation resistance tester is designed with multiple voltage levels, allowing it to meet a wider range of voltage testing requirements. High Accuracy: The insulation resistance tester boasts a high level of accuracy, with a range of ±(3%+5dgt) for 0.00MΩ-99MΩ and ±(5%+5dgt) for 100MΩ-11.0GΩ, ensuring precise measurements and reliable results. Buzzer Alarm: The insulation tester is equipped with a buzzer alarm that sounds when the insulation resistance of the device being tested falls below 4MΩ. Wide Application: The insulation resistance tester can be used in a variety of applications, including electromechanical installation testing, cable testing, electrical equipment testing, power transmission testing, insulation fault detection in new energy vehicles, and insulation testing in new energy vehicles.
