HOW TO READ TRUE ELEVATION IN FEET, TENTHS AND HUNDREDTHS

YELLOW BACKGROUND – BLACK NUMBERS

1. Set rod foot on a benchmark or hub with a known elevation; i.e. 2,525.25 elevation.

2. Run the laser receiver up or down the side of the rod and / or raise or lower front rod section until

you get the “on grade” signal on your laser detector. If you are using an optical instrument, site to

the rod and use the horizontal line as your grade reference.

3. Loosen the tape lock pin (lower knob) and disengage the tape pin from the grommet.

4. Roll the tape face until 5.25 is across from the pointer on the laser detector bracket, or the horizon-

tal line on your optical instrument. You are using the last whole number and the decimal numbers

of 2,525.25.

5. Lock the tape by engaging the tape lock pin into the nearest grommet. Then tighten the knob. You

have now locked into the rod elevation (2,525.25). All future readings will be true elevation above or

below 2,525.25 (5.25).

6. To find an elevation, simply set the rod foot at any location on the job within the range of your laser

or optical instrument. Run the detector and / or front rod section up or down until you pick up the

“on grade” signal from your detector. Read the number opposite the pointer. That number is your

true elevation. If using an optical instrument, just read the number across the horizontal line. That

number is your true elevation.

EXAMPLE:

Rod reading is 6.10 = 2,526.10 true elevation

Rod reading is 8.32 = 2,528.32 true elevation

Rod reading is 4.70 = 2,524.70 true elevation
