Features
Ground resistance meter 3-electrode measurement on the 3151 gives greater precision !
Ground resistance measurement involves factors that are not encountered during ordinary resistance measurement, such as polarization of the earth, the influence of grounding current due to leak current and grounding voltage, and the influence of auxiliary grounding resistance. The 3151 is able to make more accurate measurements more safely under difficult conditions because it uses the alternating current potentiometer method to provide measurement accuracy, and because it contains features such as an auxiliary grounding resistance check feature and measurement frequency switching.
Differences between the Model 3151 and 3143
Common ground resistance meters such as the 3151 measure the resistance using a frequency between 500 Hz and several kHz.
The 3143 uses a frequency between 100 kHz and 1.5 MHz, close to that of a lightning surge. Therefore, measurement errors can result if the 3143 is used in situations such as the following.
In these instances, we recommend using Model 3151.
Electrical grounding or mesh grounding.
Electrical power equipment grounding.
When the measurement point is located at a distance from the insertion point of the grounding electrode.
