Highest Readouts and Number of Decimals

There is a maximum distance which the Plan Wheel can display. This varies depending on the units of readout chosen. Also depending on the units of readout, a different number of digits will be displayed following the decimal. The following chart shows the maximum reading and number of digits for each unit of readout possible on the Plan Wheel:

If you roll past the maximum reading, the display will show all dashes (-------). However the Plan Wheel continues to accumulate distance internally. The measurement can be recovered by switching to larger units; for example, from feet to yards.

The number of digits after the decimal does not necessarily reflect the resolution of the readout. Resolution of readout = 1.0 mm (0.04") wheel resolution times the scale factor.

Examples: For a scale of 1:100 and reading out in meters, the resolution is 1.0 mm times 100 = 0.1 meter. For a scale of ¼" = 1' (1:48) and reading out in feet, the resolution is 0.04" times 48 = 1.92 inches or 0.16 feet.

This chart applies to the Plan Wheel PC as well as the Plan Wheel.
