Getting started You may want to practice getting a feel for your calculator keys by reading through the key definitions and learning how to enter basic feet-inch-fractions and metric, how to store values in Memory, etc., before proceeding to the examples. Order of Operations Unlike other Calculated Industries calculators, which use the Chaining Method of Operations, this calculator uses the Order of Operation Method.

PERCENTAGE CALCULATIONS The keys can be used for finding a given percent of a number or for working add-on, discount or division percentage calculations. It can be used with any type of number, in any dimension (feet, inch, millimeter, etc.) and any type of convention (non-dimensioned, linear, square or cubic).

Using Memory Storage Keys (M1 - M9) In addition to the standard cumulative Memory (as previously described), your calculator has nine independent Storage Registers – M1 through M9 – that can be used to permanently store single, noncumulative values. The following example shows the use of M1 ( ). To use M2 - M9, replace the presses of the key with presses of the corresponding number key ( - ).
Example: Store 175 into M1, recall the value, and then clear the value. KEYSTROKES DISPLAY M-1 175. 0. M-1 175. M-1 0. 4094-Inside Pages_Corrected.

Calculate Costs The Cost function provides the total cost for material, based on a stored unit cost and an entered quantity of material. This is convenient for quickly calculating costs on a job that requires many of the same kind of items. Example You are doing an installation that includes 120 feet of pipe that comes in 10' lengths at $3.21 per 10' pipe. KEYSTROKES DISPLAY Store the unit cost of the pipes needed: 0. COST Per 3.
You can also find costs of different items on the fly without overwriting your stored unit cost. Determine the cost of 17 fittings at $2.89 each: KEYSTROKES Enter number of pipes needed: Multiply by the cost: (Cost) 4094-Inside Pages_Corrected.indd 26 DISPLAY 0. 17. 2.89 TTL$ 49.
Using the Plumbingcalc Pro Note: The PlumbingCalc Pro’s built-in rightangle functions, including Offset, Run, and Travel, are designed to calculate centerline lengths only and do not account for take outs or welder’s gaps. Refer to your calculator’s User’s Guide for examples using these functions in conjunction with take outs and welder’s gaps. Pipe Material Key The Pipe Material key lets you choose a pipe material, which defines the available sizes and surface roughness used by the calculator.
The last material setting displayed is selected, and the calculator will retain your setting even after the power has been turned off. Once a material is selected, you can easily toggle through the available types (Schedules, etc.) using the Pipe Type function. Available types of pipe are dependent upon the material setting. Keystrokes below show the pipe types available for Plastic (press until “PLASTIC” is shown in the display).
Pipe Size Key Pipe sizes are entered with the Pipe Size key. There is a list of valid pipe sizes for each Pipe Material in the User's Guide. When you have chosen a Pipe Material and Type and then enter Pipe Size, the following data will be displayed. For this example we are using 3” Plastic, Schedule 80 pipe. KEYSTROKES DISPLAY 0.

appendix Auto-Shut Off Your calculator will shut itself off after about 8-12 minutes of non-use. Reset If your calculator should ever “lock up,” press Reset — a small hole located above the [Angle/Slope] key— to perform a total reset. Batteries This model uses two (2) LR44 batteries (included). Should your calculator display become very dim or erratic, replace the batteries. Note: Please use caution when disposing of your old battery, as it contains hazardous chemicals.
