I set up a direct fault using 18 ga wire tonite.

I measured short to earth of the wire 1881

The general earth conductivity was 900

The conductivity at the ground stake was 099 / 082 modified

Condvctivity at the fault was 585

All measurements were taken with a DMM set at 2000kohms.


Basically the ground conditions were what i would be seeing in jvne/july in my area.

With the transmitter set on low, receiver sensitivity at 12 o'clock i had detectable kick 30 ft from the fault in any direction and good kick at 6 o'clock.

I wet the return path and the response increased at lower sensitivity levels.

I noticed the fault directional change is about 4 in inside the frame. Don't know if this helps or not.

Give me a few weeks and i can prolly tell you more.

I miss the Dynatel, i have been spoilt. LCD, current strength, resistance and continuity readings for return paths. Aw what a machine she was.
