2.1 Required Tools
•
1/4” nut driver or T15 Torx driver
•
Digital or bubble level calibrated and accurate to 0.1° at level
•
Digital volt/Ohm meter capable of measurements to three decimal places
•
100 foot measuring tape: Fiber-type graduated in tenths of a foot
NOTE: The computer calculates measurements in feet and tenths of a foot. Using the correct
tape measure is critical for entering the measurements.
If a standard tape measure is being used, convert the measurements into feet and tenths of a foot. For
example: Enter 35’-6” into the system as 35.5 feet. To convert whole inches, divide by 12 (6/12 = .5).
Fractions of an inch are converted by dividing the numerator by the denominator.
Enter 1/4” inch as .25 (1/4 = .25). Convert whole inches and fractions of an inch, for example 6-1/4”, by
converting the fraction to a decimal then dividing by 12. In this case, 6-1/4” is converted to 6.25 and
then divided by 12, which equals 0.520.
When entering weights, convert the number by moving the decimal three places to the left. For example,
enter 1,400lbs as 1.4, enter 300lbs as .300.
