Read the planimeter manual to make yourself familiar2. Basic operations are: 1. Turn it ON2. Press m ↔ ft to toggle between SI or customary system3. Press UNIT (press more than once to get the correct unit for your use)4. Find out the scale of your drawing in dimensionless units: For example if 1 in on the paper corresponds to say 10 ft then the scale is 1 in to 120 in – which is 1 to 120. You will need to input this scale by pressing 120 followed by SCALE5. You can start measuring the area of your interest by: (1) staring at a point on the perimeter of your area, (2) pressing “START”; (3) following the perimeter of the area clockwise until you reach the point where you started; (4) press END – the number on the screen is the area. Typically you need to repeat the procedure at least 3 times and use an average.Cut/Fill Volume CalculationsCut/Fill Volume Calculations1002003001002003Design Constraints for Base, Final Design Constraints for Base, Final Grades, and Grades for Grades, and Grades for BermsBerms1. Base grades shall not be steeper than 1 V to 3 H2. Final grades shall not be steeper than 1 V to 4 H3. Surface grades for a berm or an embankment shall be not be steeper than 1 V to 3 H 4. If any cut or fill slope is longer than 60 ft, use a minimum 10 ft wide bench5. The corners for any graded contours shall be wider than 90 degrees6. Illustrate the above constraints on the chalk board.4Instructions for Using Instructions for Using PlanimeterPlanimeter--LocationLocation1. Planimeters and Digital Length Measures are stored in the Survey Lab (near the Soils Lab located on the first floor of EB)2. DO NOT take the instruments outside the lab3. Planimeter is a fairly sensitive and delicate instrument. Hence, handle it with care. Do not drop, and store it in its box when you are done.4. You will need to contact Joseph (3-6088 or 3570/78 EB) to open the survey lab and lock the door when you leave5. GOOD LUCK with the new
