Product Content Description:

General Information:
UN2571 Digital Earth Resistance Tester is applied to test earth resistance of various equipment and conductor resistance value of low resistance. It's widely used in power electric, posts, railroad, communications, mine divisions and etc.
1. High strength aluminum alloy carrying case.
2. High anti interference ability. In order to avoid inference from power frequency, radio frequency, the device adapts phase-locked loop tracing detection synchronism method, and to be equipped with switched capacitor filter.
3. DC/AC turning technology can make DC turning to AC low frequency constant current, and easy to measure.
4. Allowed auxiliary earth resistance is changed within 0~2KΩ (RC), 0~40KΩ (RP), no influence on the test result.
5. LCD screen, can test including earth resistance, low resistance conductor resistance, soil resistivity and AC earth voltage.
6. The meter displays "1" means overflow, if the test circuit is blocked.
