CA6470N ground resistance tester @CA6470N%
Portable digital grounding resistance measuring instrument: CA6470N can be used to measure thegrounding resistance, soil resistivity, ground coupling and the welding point resistance.
CA6470N measurement of grounding resistance from 0.01 to 99.99k Ω, automatic range switching, automatic matching measurement range, the best measuring frequency and measuring the current is instrument. Measuring frequency is adjustable from 40 to 5078Hz(manual or automatic), and the anti-jamming design, can be used for a variety of complex and bad environment (such as the existence of discrete current measurement accuracy)
Can store 512 groups of measurement results, can checkon the instrument, but also by the DataView ® softwareinto PC, automatically generate reports.
Product features:
3 electrodes method of grounding resistance measurement
3 electrodes method ground coupling measurement
Electrical noise in manual or automatic 40Hz to 513Hz frequency scanning to improve the measurement accuracy
Optional test voltage of 16V or 32V, measuring the current can be as high as 250mA
4- method of soil rate measurement (automatic calculation of Rho one, Wenner method or Schlumberger optional)
Resistance measurement method of 2 line or 4 linewelding (DC resistance), automatic reverse current
Automatic power management
Automatic recognition of various electrode connection
Can store 512 groups of test results
Optically isolated USB communication interface
The DataView ® software, remote configuration and all measurements
Rechargeable nickel metal hydride (NiMH) battery
Rugged dustproof and waterproof housing
DataView ® software
Product application:
The 3 electrode method to measure the grounding rods or grounding resistance, the method is only suitable foreasy opening grounding wire occasions
Soil resistivity measurement of soil resistivity, location ofthe lowest position, make the grounding device is more economic and reasonable
Potential measurement, with 3 electrodes method before measuring, used to evaluate the electrical safety. When unable to disconnect the ground wire, when the failure is likely to occur, when the grounding device and the measured size is comparable, suggest potential measurement.
The resistance and conductivity test method of 2 line or 4line method for measuring welding, DC test current to 250mA or higher, which can be used for all ground connection point detection system
Ground coupling measurement and display, for influence between the two grounding resistance evaluation of disconnected
