Instroduction:WDJD-4 Multi-function Digital DC Resistivity/IP Meter is our new generation model with 32 single-chip and 24 bit A/D technology on the basis of years of experience of design and manufacture,which could carry on Res and IP survey at the same time. It features multiple functions, high accuracy, fast speed, high reliability and excellent expandability. Measured data of WDJD-4 can be processed by other multi-electrode resistivity software, which makes the interpretation more convenient.The single WDJD-4 can conduct general electrical resistivity/IP survey with twist pair wire, iron electrodes and power source. If WDJD-4 is used together with WDZJ-4 multiplex electrode switcher multi-electrode cable, electrodes and power source, it can conduct not only general electrical resistivity/IP survey but also multi-electrode 2D Resistivity imaging.Underground water inspectionEngineering geology inspecting as dam base exploration and floodMetal and Non-metal source explorationCity geophysical explorationRailway and bridgeTechncial Specification:Receiving partVoltage channel: ± 6 VSurvey precision: if Vpâ?¥10 mV then ± 5â?° ± 1 LSB, if Vp < 10 mV, then ±1% ± 1 LSBInput impedance: â?¥50MΩApparent polarizability precision: ±1% ± 1 LSBSP compensation range: ±1 VCurrent channel: 5 A, survey precision: if IPâ?¥ 10mA then ± 5â?° ± 1 LSB, if IP < 10 mA, then ±1% ± 1 LSSuppression: â?¥80dB for 50Hz industrial frequencyTransmitter partVoltage maximum: 900VCurrent maximum: 5A( when voltage â?¤ 900V )Pulse width: 1ï½? 60s, duty ratio 1:1OtherOperating temperature: -10â??ï½?50â??, humidity: 95 %RHMemory temperature: -20â??ï½?50â??Instrument power: eight D size batteries (or same specs nickel-cadmium battery)Complete appliance current: â?¤ 55mAWeight: â?¤ 7 KgDimensions (LÃ?WÃ?H): 310mm X 210mm X 210mmStandard configuration List of WDJD-4 undergound water finderNo.DeatilsQty1WDJD-4 Mianframe1 Set2USB Communication Line1 Set3Charger1 Pc412V Power Input Line1PC5Instrument backpack1PC6Windows Software U Disk1PC7Operational Manual1PC8Unpolarized Electrodes1Pair9Iron Electrodes10PCS
