Detail
Soil Resistivity Tester DY4300
Description:
It is specially designed for on-site measurement of grounding resistance and adopts digital and micro processing technology. It has a unique line resistance calibration function,anti-interference ability and environmental adaptability to ensure high accuracy, high stability and reliability of long-term measurement. It is widely used in the measurement of grounding resistance of electronic power, telecommunications, meteorology, oil fields, buildings,lighting protection and industrial electrical equipment.
Features:
1.2/3/4-Wire Digital Earth Resistance.
2.Designed to meet following safety standards.
IEC 61010-1(CAT.I II 300V, CAT. IV 150V, Pollution degree 2)
IEC 61010-031 (Requirements for hand -held Probes)
IEC 61557-1,5 (Earth Resistance Tester)
3.Stable measurement results can be obtained under noisy environment by introducing the FFT(Fast Fourier Transform) technology.
4.Dot-matrix 192x64, Monochrome LCD.
5.Backing function to view the test results in dimly areas.
6.Can switch frequencies of measuring signal 4-kind of frequencies :94/105/111/128Hz, are selectable by hand or automatically.
7.RK Function is available to cancel the residual resistance on the Test Leads.
8.Battery Check Function.
9.Can measure Series Interference Voltage/Frequency Voltage values and frequencies are displayed when Series Interference voltage(AC) exist.
10.Auxiliary earth resistances are measured and displayed.
11.Warnings are displayed on the LCD when auxiliary earth resistances are too high and may result in inaccurate measurements.
12.Auto-Power-Off Function.
13.The instrument is automatically powered off when 5 min passes without any Key operation.
14.Memory Function.Can save 800 measured results.
15.Direct measurement of soil grounding rate by quadrupole method.
16.Grounding resistance test of 6 ranges within the range of 0.001 Ω - 200K Ω.
17.After setting the spacing of auxiliary grounding rods,the grounding resistance test results are automatically calculated.
18.Warning function in case of super interference or high auxiliary grounding resistance.
19.Automatic mode, the instrument automatically selects the most appropriate frequency.
