What does s stand for as in 10s of meters ? *(Presumably metres)*


I thought distance apart made no difference in homogenous soil ?

Quoting Hugh M0WYE <[email protected]>:

.

However I got similar readings to you - around 10 ohms - with moist, garden soil.

I found the most repeatable readings were when one current and one voltage probe, 1m apart, were seperated by 10s of meters from the other pair - as is

used for archeological ground resistance surveys.

To discuss

Measure ground conductivity.


I placed two stainless- steel rods ( 3mm dia ) whithin a distance of 7 Meters apart abt 80cm deep into soil

Powered with 50 Hz.
In series with the electrodes is a 10 Ohm resistor. In order to measuring current, I measure the voltage drop across resistor.

Depending on weather I got 8 Ohm / m = 125mS

Is this measurement setup ( proceeding ) correct ?

Please correct me.

Uwe, DK1KQ
