Introduction to the performance of groundwater detectors

- Jan 08, 2019 -

  The groundwater detectors is small in size, low in power ;consumption, and has many functions. If the operator does ;not operate for 10 minutes, the instrument automatically turns off the power.;The receiving part has the instantaneous overvoltage input protection capability, and the transmitting part has overvoltage, overcurrent and AB open circuit protection capability. Multi-parameter, multi-method - the instrument can directly give the natural potential, apparent resistivity, apparent polarizability, half-life, attenuation, excitation ratio, deviation and comprehensive parameters and other water-seeking parameters, working in the quadratic time difference method At the same time, the instrument can also give the second time difference parameter and the quality discriminant parameter to draw the measurement parameters on the whole line on the large screen display, and the measurement result is straightforward. The full Chinese character touch panel is equipped with a Chinese character menu prompt, which is extremely convenient to operate. The working cycle can be set arbitrarily, and there are 9 kinds of field working methods to choose and their pole distance constant, device constant input and calculation function, pole distance constant table - for all devices, up to 100 sets of different pole pitch constants can be pre-stored In order to avoid the input errors that may be caused by repeated input of the same pole pitch constant, only one number can be input to call up or reset the corresponding group pole pitch constant. Grounding resistance check - It is convenient and practical to check the grounding of each electrode at any time. Ultra-large-capacity data storage—Measurement parameters are stored along with the pole-distance constants, and the instrument can store up to 2,250 points of data. All instrument setting parameters and measurement data have power-down protection. The equipped RS-232C interface can work with other microcomputers. The diagnostic program quickly and accurately determines the location of the fault and the major damage to the device. The fully sealed structure has the advantages of waterproof, dustproof and long life.
