AEMC Instruments 6471 Kit-300ft Description:
Portable measurement instrument designed to measure ground resistance with 2 clamps (no auxiliary rods), bond/connection resistance (2-pole and 4-pole Kelvin sensing), ground resistance (3-pole or 4-pole), ground coupling resistance, and selective ground resistance, soil resistivity (Wenner or Schlumberger method). In addition, this ground resistance tester measures from 0.01 to 99.99 k? and is auto-ranging, automatically seeking out the optimum measurement range, test frequency and test current.
Features
- Test ground resistance using the 2 clamp method (no auxiliary rods needed)
- 2- and 4-pole bond resistance/continuity measurement (DC resistance) with automatic polarity reversal
- 3-pole fall-of-potential measurement with manual or automatic frequency selection
- 4-pole Soil resistivity measurement with automatic calculation of ? and user selection of the Wenner or Schlumberger test method
- 3-pole earth coupling measurement
- Manual and automatic frequency scan from 41 to 513 Hz for optimum test accuracy in electrically noisy environments
- Selectable test voltage of 16 or 32 V up to 250 mA of test current
- Auto-off power management
- Automatic recognition of all electrode connections and their resistance value
- Stores up to 512 complete test results in internal memory
- Optically isolated USB communication
- Remote set up and operation of all measurements using DataView® software
- Rechargeable NiMH batteries from wall charger or vehicle power
- Rugged dustproof and rainproof field case - IP54 rated in closed position
- Grounding standards IEC 61557 parts 4 and 5 compliant
- Includes DataView® software for data storage, real-time display, analysis, report generation and system configuration
Applications
- Measure ground rod and grid resistance
- Use in multi-grounded systems without disconnecting the ground under test
- Measure resistance and continuity of grounding loops around transformer pads and buildings
- Measure leakage current flowing to ground or circulating in ground loops
- Conduct quick field checks
- Conduct field surveys and retrieve and analyze readings from stored data
- Measure earth resistance of the type of single rod or small ground grids often found in remote telecommunication switching stations
- Measure ground electrode resistance on lightning protection equipment
- Measure the earth electrode resistance of equipment in recreational areas, especially public swimming pools
- Test electrode resistance of installed ground rods and grids at new construction sites before utility power is supplied
- Test earth electrode resistance of grounded towers and counterpoises at cellular phone remote installations and power transmission towers
- Three-point measurement of large grounding grids, counterpoises, ground mats, and grounded equipment
- Locate areas of lowest soil resistivity which is essential for achieving an economical grounding installation
