| Referring to the impressed current cathodic protection system shown in the illustration, if required to control the current to the anodes manually by using the hand adjustment potentiometer, what statement best represents the changes that should prompt one to recheck the reference electrode voltage (hull potential)? EL-0090 |
| A) Changes in vessel speed, sea water temperature, and sea water salinity should all prompt rechecking. |
| B) Changes in sea water temperature and vessel speed should all prompt rechecking. Changes in sea water temperature need not prompt rechecking. |
| C) Changes in sea water temperature and sea water salinity should all prompt rechecking. Changes in vessel speed need not prompt rechecking. |
| D) Changes in sea water salinity and vessel speed should all prompt rechecking. Changes in sea water temperature need not prompt rechecking. |
