Test & Measurement Equipment - Sales, Service,Rental and Calibrations

Model 6470-B Kit 300 includes meter, NiMH battery pack, optically isolated USB cable, Dataview software, battery charger, power cord, users guide two 300 foot colour coded leads on spools (red/blue), two 100 foot colour coded leads (hand tied, green/black), four T-shaped auxiliary ground electrodes, set of 5 spaded lugs, one 100 foot AEMC tape measure, ground tester workbook CD, carry bag.

The Digital Ground Resistance Tester Model 6470-B is a portable measurement instrument designed to measure Ground Resistance, Soil Resistivity (2 x methods: Wenner and Schlumberger), Bonding Resistance (DC Resistance 2-wire and 4-wire Kelvin sensing) and Earth Coupling resistance. This direct reading tester measures from 0.01 Ohm to 99.99 kOhm and is auto ranging - automatically seeking out the optimum measurement range and test current.

The 6470-B is easy to use - simply connect the leads, select the test mode, press Start and read the results. Up to 512 test results can be stored in internal memory for later recall to the display or downloaded to a PC via the Dataview software.

The large LCD is easy to read and indicates ground electrode resistance, test voltage, current and frequency as well as individual electrode resistance, battery status and more.

The 6470-B is Cat IV rated to 50V and is over voltage protected to more than 250VAC against accidental connection to love circuits. The voltage is also displayed on screen. In the event of a system fault, the Model 6470-B can withstand 250VAC.

Additional features of the 6470-B include a heavy-duty filed case sealed against dust and water when closed (the test button is also sealed against the elements); manual and automatic test frequency slelection from 40 to 513Hz; user slectable 3-Pole (3-Point) Fall of Potential or 4-Pole (4-Point) Soil Resistivity test methods and user selectable 2-Wire or 4-Wire Bond Resistance test method.

The 6470-B is powered by 9.6V, 3.5 Ah NiMH rechargeable batteries. An external recharger is included and provides for testing while recharging.

The 6470-B Ground Resistance Tester is rugged, easy to use and ideal for maintenance crews performaing numerous tests. It exceeds mechanical and safety specifications for shock, vibration and drop tests per IEC standards. The adjustable test frequency provides for rejection of high levels of interference, allowing it to be used under difficult conditions such as high stray currents that normally affect accuracy.

Applications
