must be approximately 6 feet apart and the resistance between the rods (without
the cable connection) should be 3 ohms or less. The resistance of the soil can be
reduced by adding copper sulfate or salt water around the rods. A drip system may
be required to insure maintenance of a proper ground.
NOTE - BE SURE THAT THE POWER SUPPLY CANNOT BE
TURNED ON DURING THE FOLLOWING TEST.
At least once a year the wire between the two rods should be disconnected and
the soil resistance checked. The resistance should never be over 3 ohms. The
climate and soil conditions in your area may dictate performing this test more
often. After this test has been completed, reconnect the cable to both rods before
returning the power supply to service.
If the equipment is to be installed in the upper floors of a building where the
installation described above is not feasible, the system may be grounded by
connecting the vacuum chamber to the steel structure of the building. This should
be done only after verifying that the building structure itself has a good earth
