Each officer, by or for whom interim successors are designated under the provisions of this chapter, shall, immediately after their designation, instruct his or her interim successors how to exercise the powers and discharge the duties of his or her office. Only while actually exercising the powers and discharging the duties of an office shall an interim successor receive any compensation, but while so doing shall receive the pro rata salary or other compensation, including perquisites, provided by law for the office.
