The Scale Master Classic is a digital plan-measuring tool that is commonly used in engineering, building construction, landscaping and telecommunication as well as other professions. Its main function is to provide accurate area, linear and volume conversions. This is a useful piece of equipment when it is used correctly. You can prevent errors, improve profit and improve productivity by using the Scale Master Classic. You can start enjoying the benefits of your Scale Master Classic by following these basic instructions.

Step 1

Press the "Off/On" button to turn on your Scale Master Classic tool. Press the "Mode" button to toggle between scale modes such as "ARCH" for architectural or "ENG I" for engineering.

Step 2

Press the "M1+" button to store a length in order to calculate an area. Use "M2x" to store a width in order to calculate an area. Press "[Rcl] [M2x]" to display the area that is calculated from both the length and width.

Step 3

Step 4

Switch back and forth between units by pressing and holding "Subtract/Count" and "Mode" simultaneously.

Step 5

Enter a custom scale by pressing the "Mode" key. "1: CUS 1" will appear on the display screen. Press and hold both "Subtract/Count" and "Scale" together. Press "Scale," then press "M1+" to increase the digits. To decrease the units press "Subtract/Count." Press "Scale" to move to another digit. Press the "Scale" option until all the digits are set and stored in the Scale Master Classic unit.
