Jim,
Having taught bonding classes for a decade, you really should know that a
Simpson 260 is completely worthless for ground conductivity measurements.
Just saying. We in the electric industry use a high voltage megger to do
this.
Mine runs at approximately 500 volts DC.
This is used in commercial and industrial electrical work. I am also
required to Meg any ground connection at a residence to under 25 ohms.
Where I to bust out my Simpson meter, I'd lose my license.
Caught you stating you used a Simpson for ground resistance measurements
before. Forgot to correct ya on that one.
