the location of the anode so that it can be located easily, as
"gas line 50' W to 10' N of building 2263."
E. Date Installed. Enter date of installation. This
date will be supplied by the corrosion engineer. Where no
detailed information is available, estimate and enter
Item 7. Operating Record:
Column A. The month tests are performed.
Column B. Enter the date of the month of the survey.
Column C. Structure-To-Soil Potentials At Test Station
(Volts). This reading will usually be taken at the test
station(s) of the system. Where no test stations are installed,
readings must be taken at point as directed by the corrosion
engineer. Enter the value found in column C.
Column D. Structure-To-Soil Potential Between Anodes
(Volts). This is the potential-to-ground of the structure
halfway between two anodes (or the most remote point of a
structure from the anode protecting it). It is important to
know how far the protection of an anode extends. Enter the
value in column D.
Column E. Anode-To-Soil (Volts). This reading
represents the open circuit voltage of the anode with the
structure (load) disconnected. Enter the reading in Column E.
Column F. Anode-To-Structure (Milliamps). Connect the
milliamp meter between the structure and anode at the test
station and enter the value in column F.
Column G. Soil Conditions. State whether soil is wet,
moist, dry, or powdery. The condition of soil is approximately
1 foot below surface. If the ground is frozen, do not take
readings and so state by entering "GF."
Column H. Initials of Technician. The initials of the
cathodic protection technician (CPT) must be shown in this
Signatures: Each log must be signed by the (CPT) and the base
corrosion engineer before submission to higher headquarters.
