this instrument can also measure soil resistivity and ground
voltage.
3. Main features
1) High-strength aluminum alloy shell body, the circuit
equipped with phase locked loop and switched capacitor filter,
based on which the instrument play an effective role in shielding
power frequency and radio frequency interference.
2)
DC/AC converter can transform DC current into AC
low-frequency constant current for the measurement.
3)
Auxiliary grounding resistance can change in the
range of 0 ~ 2KΩ (RC), 0 ~ 40KΩ (RP), that will not affect
measurement results.
4)
Without manual adjustment to zero, with three and a
half bits LED display, the instrument can be used for
measuring the grounding resistance, the conductor resistance
of low resistance, soil resistivity and AC ground voltage.
5) If tested loop encounter failure, the screen displays
"1" indicating large range, which consistent with conventional
measurement practices.
