For measurement of the ground resistance are man was to do it:
I use a HP 4192A Impedance Anazer ( 5Hz - 13MHZ) to look also at AC frequences.
Another wa to measure the DC resistance is to connect a powersupply (10 V / 10 A) between normal groun and audio ground. Increase the voltage slowly till you get a reading of about 5 amps. Than you can calculate the ground restance = Voltage divide by amps. Don´t forget to swithch all your equipment off before!
Best regards
Stephan
