1. Product introduction
NR3571 Ground Resistance Tester applies to measure ground resistance of various devices and low resistance conductor resistance in electricity telecommunications railways telecommunications mining and other sectors; This tester also can measure soil resistivity and ground voltage.
2. Characteristics and functions
● Adopt high strength aluminum alloy case in order to prevent power frequency and radio frequency interference it uses phase-locked loop synchronously tracking detecting method and also equip with switching capacity filter that make the tester with high anti-jamming capability.
● Adopt DC / AC conversion technology change DC to AC low frequency constant current in order to measure.
● Allow the earth resistance changing between 0~2KΩ (RC) and 0~40KΩ (RP) it does not affect the measured result.
● No need to regulate balance artificially 3(1/2) bit LCD display not only can measure the earth resistance but also can measure low resistance conductor resistance earth resistivity and AC earth voltage.
● If measure the test loop fails the meter shows "1" means overflow that conform to the standard habit of measurement.
