The instructions in section 8.3 should be relocated to 8.7. Sections 8.1 through 8.5 describe setting up the instrument and measuring the zero correction time. Currently, section 8.3 refers to separating the transducers by the distance, through which, the measurement will be made. Section 8.7 discusses placement of the transducsers. It is logical for the instructions currently found in section 8.3 to be relocated to section 8.7.
