USER’S GUIDE — 33
The Sheet Metal/HVAC Pro Calc calculator has keys and functions
labeled in common sheet metal/HVAC or construction terms. Just
follow the examples and adapt the keystrokes to your specific
application.
Your calculator will save
you time; you don’t need to remember
common formulas, as they are built into timesaving keys.
The first examples that follow provide you with mathematical
problems seen in the sheet metal industry, such as computing
triangle meas-urements using the Pythagorean Theorem or the Law
of Cosines, as well as dedicated Offset, Fan Law, and Velocity
functions.
The remaining examples apply to the construction trades, especially
roof framing, which also depends on Right Triangle mathematics.
It is good practice to clear your calculator (press otwice) before
beginning each problem. And remember to use the Backspace
(B) key to correct entries one entry at a time.
