Soil Resistivity Measurement - Circutor TL-6e Manual De Uso

8. Soil resistivity measurement

NOTE: in this function, the equipment operates only with the 270 Hz
frequency.
To select the resistivity measurement function press the key. Insert
four rods in the ground, well aligned and with an equal distance from each
other. Connect them to the output terminals using the supplied cables.
Remember that the distance between rods is very important when
measuring soil resistivity, since this value is part of the calculation.
Specify the distance between rods ("a" in the image below and on the
display) by using the and keys ( and to increase or
decrease only one meter at a time).
