Description
AEMC model 6472 multi-function ground resistance tester is a portable measurement instrument designed to measure bond resistance, ground resistance (with and without clamps), soil resistivity, earth coupling and step & touch potential. When used in combination with the GroundFlex Adapter Model 6474, power transmission tower and tower leg ground resistance testing is also available.
AEMC model 6472 multi-function ground resistance tester measures from 0.01 to 99.99 kΩ and is auto-ranging, automatically seeking out the optimum measurement range, test frequency and test current. The adjustable test frequency (either manual or automatic) from 41 to 5078 Hz test voltage provides rejection of high levels of interference, allowing it to be used under difficult conditions such as the presence of high stray currents that normally affect accuracy.
AEMC model 6472 multi-function ground resistance tester 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 the screen. In the event of a system fault, the model 6472 can withstand 250 V AC. Up to 512 test results can be stored in internal memory for later recall to the display or downloaded to a PC using DataView software (included) for automatic report generation, automatic fall-of-potential plot generation, frequency/ resistance plots and much more.
