CR-ER03 Double Clamps Earth TesterCR-ER03 Double Clamps Earth Tester is widely used in the fields of resistance testing for earth resistance of various equipment and building. It also can test the soil resistively and leakage current of earth systems under different conditions.  It not only possesses the function of the traditional method but the features of earth resistance testing without assistant poles, It realizes the on-line measurement of earth resistance without assistance poles and isolation of earth devices and equipments by adopting the principle of 2-poles measurement and the technology of double jaws. Key Features                                                                                                                                                          1. Adopt the measurement method in the type of jaw and meters, can be operated without assistance poles.2. Realize the on-line measurement; it is unnecessary to isolate the earth device from equipment.   3. Test the RMS of leakage current under the conditions of earth/unearth of system.  4. With the function of self-checking and avoid the influence for the test result by connecting the resistance and line resistance 5. Realize the alternation of functions, adopt the digital switch to cutover the function in order to improve the reliability of system.  6. Communicate with the upper-level PC to realize uploading of the test data which can be saved and printed easily.   7. Easy and convenient operation with broad range of usage and measurement, with the backlighting system.   8. Electrical safety: It should agree with the standard of IEC1010-1, EN61010-1 or IP53.Technical Specifications                                                                                                                                       ModelCR-ER03Measuring range for the four-wires measurement method: 0.00Ω~19.99K Error:0.00Ω~19.99Ω≤±3%+4pxs20.0Ω~19.99KΩ≤±5%+4pxsMeasurement method of four-wires and jaw: 0.00Ω~1.99KΩ Error:0.00Ω~1.99KΩ≤±3%+4pxsFor double jaws: 0.00Ω~100ΩError:0.0Ω~19.9Ω≤±10%+3pxs20Ω~100Ω≤±20%+3pxsFor resistively of earth resistance: 0.00~1999KΩm Error:0.01Ωm~1999Ωm≤±3%+4pxs2.00KΩm~1999KΩm≤±5%+4pxsFor the leakage(RMS): 0.0mA~19.9A Error:0.0mA~9.99A≤±3%+4pxs10.0A~19.9A≤±5%+4pxsStorage capacity:250 groups of datasWorking temperature:-10℃~+55℃Storage temperature:-30℃~+70℃Power supply6 V DC, 4 × 1.5V AA alkaline dry battery or 4.8V DC, 4×1.2V AANi-Mh recharge battery Weight:1.0㎏(exclusive of accessories)Dimension215×115×85mmWhy Choose Criane?                                                                                                                                            Start from 2003* Professional manufacturer and OEM factory.* Independent R&D office and team. * 4 numbers of production line * ISO 9001-2000 certificate * High-tech enterprise proofed by government departmentExcellent sales team* Response inquiry in 30 minutes in working time, and 12 hours in off working time. * With professional products knowledge and oversea sales skills.  * Always warm and thoughtful service.4 numbers of production line.* Clean and tidy production office.* Military production process. * Humanized production management and skilled production team. Pre-Sales Service* Inquiry and consulting free. * Sample demonstration and experience. * Welcome to visit and inspect our Factory.After-Sales Service* Training how to install the machine, training how to use the machine. * Engineers available to service machinery locally or online. * 15 months warrantyAs a professional manufacturer and supplier of clamp on ground resistance tester/earth loop tester for sale, we warmly welcome you to wholesale the high quality and reasonable price equipment for sale from our factory.
