THE JUDICIOUS USE OF WORDS CAN CLARIFY DESIGN INTENT
INTERRELATED INSTRUMENTS WHOSE SYMBOLS ARE SCATTERED ON DIAGRAM. (A MULTI-POINT INSTRUMENT, SUCH AS A DATA LOGGER, THAT IS DESIGNATED WITH POINT
NUMBERS ON A DIAGRAM IS NOT EXPECTED TO HAVE THE SYMBOLS FOR THE VARIOUSPOINTS TIED OR REFERENCED TOGETHER). PEN ASSIGNMENTS NEED NOT BE SHOWN ON
A DIAGRAM IF IT IS THE USER'S PREFERENCE TO SHOW THEM IN AN INDEX.
