Let Scala Architectural and Engineering Scale change the way you measure printed drawings on the go and at your desk. With fixed and variable scales there is no limit to measuring a printed drawing of any scale, even if the scale is unknown. FIXED SCALES If you know the scale of a drawing, place your device on the drawing, scroll to the scale of the printed drawing and watch the chosen scale slide in. VARIABLE SCALES If the scale of a drawing is unknown, slide your finger on the variable scale and match the scale of one known element, lock it and use it to measure all elements on that drawing. MEASURING Slide the measurement slider in fixed or variable scale modes, along the scale to see the desired measurement displayed. SECONDARY UNITS Choose secondary units to be displayed while measuring, to quickly convert between metric, decimal feet and feet and inches. PRECISION Control the precision of the measurement units. —-— Scala Free Version includes: ARCHITECTURAL Fixed Scales: Full Scale (12”=1’-0”), 6”=1’-0”, 3”=1’-0”, 1 1/2”=1’-0”, 1”=1’-0”, 3/4”=1’-0” Variable Scale Range: Between full scale and 1/32”=1’-0” ENGINEERING Fixed Scales: 1”=10’, 1”=20’, 1”=30’, 1”=40’, 1”=50’ and 1”=60’ Variable Scale Range: Between 1”=10’ and 1”=300’ METRIC Fixed Scales: 1:1, 1:2, 1:5, 1:10, 1:20, 1:25 Variable Scale Range: Between 1:1 and 1:1000 Scala Full Version includes all scales above plus the following: ARCHITECTURAL Fixed Scales: 1/2”=1’-0”, 3/8”=1’-0”, 1/4”=1’-0”, 3/16”=1’-0”, 1/8”=1’-0”, 3/32”=1’-0”, 1/16”=1’-0”, 1/32"=1'-0" ENGINEERING Fixed Scales: 1"=80', 1"=100', 1"=200', 1"=300' METRIC Fixed Scales: 1:30, 1:40, 1:50, 1:75, 1:100, 1:125, 1:200, 1:250, 1:300, 1:400, 1:500, 1:1000 —-—
