General Information:
SX2571 Digital Earth Resistance Tester is applied to test earth
resistance of various equipments and conductor resistance value of
low resistance. It's widely used in power electric, posts,
railroad, communications, mine divisions and etc.
Features:
High strength aluminum alloy carrying case.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.DC/AC turning technology can make DC turning to AC low
frequency constant current, and easy to measure.Allowed auxiliary
earth resistance is changed within 0~2KΩ(RC),0~40KΩ(RP), no
influence on the test result.LCD screen, can test including earth
resistance, low resistance conductor resistance, soil resistivity
and AC earth voltage.The meter displays "1" means overflow, if the
test circuit is blocked.
