1, the measured frequency equivalent good. Test current waveform is a sine wave, frequency, frequency difference is only 5Hz, 45Hz and 55Hz using two frequencies measured.
2, anti-interference ability. The instrument uses a different frequency measurement, filtering techniques with modern hardware and software, making the instrument has a high resistance to interference, stable and reliable test data.
3, high accuracy. The basic error of only 0.005Ω, used to measure earth ground impedance small network.
4 powerful. Measure current pile, pile voltage, grounding resistance, step voltage, touch voltage.
5, easy to operate. Full Chinese menu operation, directly display the measurement results.
6, a small amount of wiring work, no large current line.
1, measuring range: 0 ~ 150Ω (including current pile impedance)
2 Resolution: 0.001Ω
3, the measurement error: ± (reading × 2% +0.002 Ω)
4, the maximum output voltage: AC 400V (45Hz, 55Hz, dual-frequency, sine wave)
5, the maximum output current: AC 5A (45Hz, 55Hz, dual-frequency, sine wave)
6, the current output gear: 5/4.5/4/3.5/3/2.5/2/1.5/1A, 0.5A one file for each of 9 files.
7, anti-interference ability: anti-50Hz frequency voltage 10V
8, soil resistivity measurement range :0-999 .9 Ω / M, accuracy: ± 2%, Resolution: 0.01Ω / M
