The AEMC model 6470-B ground resistance tester is a portable measurement instrument designed to measure ground resistance, soil resistivity (two 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 to 99.99 kΩ and is auto-ranging, automatically seeking out the optimum measurement range and test current.

The AEMC model 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 AEMC digital ground resistance tester model 6470-B is CAT IV rated to 50 V and is overvoltage protected to more than 250 V AC against accidental connection to live circuits. The voltage is also displayed on screen. In the event of a system fault, the Model 6470-B can withstand 250 V AC.

The AEMC Digital Ground Resistance Tester Model 6470-B ships complete with:

NiMH battery pack
Optically isolated USB cable
DataView software
External battery charger
AC power cord
User manual
