Operator10 formulas are critical. When you’re building calculations in Operator10, small setup choices determine whether results show up exactly where you expect. This quick guide walks through the core steps: creating a location/parameter, attaching a formula, testing it, and keeping your calculation order clean.
Create the spot where results will live
Before you write anything, create (or pick) the location/parameter that will store the result. Many teams add clearly named parameters like “BOD Pounds” or “% Removal” so the purpose is obvious on data entry screens and reports.
Attach the formula (don’t type freehand)
Open the Formula Editor from the parameter and build the expression using the selector (the … button) to insert locations/parameters. Operator10 expects references in bracketed format; the picker inserts the correct syntax for you. Avoid special characters in formula names.
Test with real or sample numbers
Pick a test date that has data and preview the result. No data yet? Use the “use values from test data” option to plug in sample numbers, or highlight a bracketed reference and click the exclamation icon to see the actual value Operator10 will use on that date.
Store precision, round for display
Operator10 stores results with extended decimal precision. If you need an integer (or fewer decimals), wrap your expression with ROUND() for the value you want written to the database.
Keep calculation order in sync
Formulas run in sequence. If you find yourself clicking Calculate twice to see results, open Calculation Order and move upstream formulas (like flows) above downstream ones (like pounds).
Why this helps operators
- Results land on the right parameter every time
- Fewer formula errors thanks to the selector and test tools
- No “calc twice” surprises when order is set once
