He clicked the second tab: Columns were pre-labeled for Range (Min/Normal/Max), Output Signal, Process Connection, Material (wetted parts), Hazardous Area Cert, and even a drop-down menu for "Calibration Standard Needed."

But then, three results down, he found it. A clean, simple link: Instrument Index & Datasheet Template.xlsx from a control engineering blog run by a retired instrument tech named "Old Greg."

He clicked the second tab. "Here are the pressure transmitters. Note the yellow highlights—that's me flagging three units that exceed their normal range by 8%. Recommend replacement before startup."

Marco plugged in his laptop and projected the Excel file onto the wall screen.

The fourth tab was a page that automatically converted his ranges (psi to bar, °F to °C) and flagged any tag where the max range exceeded the sensor's limit—in yellow, no less.

Diane didn't say "good job." She didn't have to. She just nodded, wrote something in her notebook, and said, "Send me that file. And the template link."

The search results loaded. At first, it was the usual mess—sketchy "free download" sites that wanted his work email and a credit card "just for verification," forums where engineers argued about whether a datasheet should include a "wetted material" column or not, and links to expensive engineering software suites.

For the next four hours, Marco worked like a man possessed. Instead of retyping column headers, he copied and pasted. Instead of doing unit conversions by hand, the template did it for him. He imported the 47 PDFs as images on a second screen and just typed over the template's sample data. By 3:00 AM, the Instrument Index was complete. All 47 tags, cross-referenced, ranged, and certified.

He sighed, opened a new browser tab, and typed the words that felt like a small surrender:
