Equipment Calibration Ritual

Calibrations overdue — instruments past their calibration date or never calibrated — every measurement they make is unverified, and an auditor traces it back to the last certificate.

The Monthly page

What the file tells you every month

Every instrument whose reading you rely on — scales, probes, torque wrenches, gauges — with its interval, last calibration and who does it; every calibration with its result. Once a month the sheet says what is overdue and must be quarantined, what to send to the lab, and which instruments keep drifting.

01 · verdictOverdue — how many, the most overdue, what to quarantine
02 · verdictComing — what is due inside the window and what it costs to send
03 · verdictDrift — 12-month failure rate, outright fails, the last one
Sheets in the workbook
✓Monthly · overdue, coming, drift, three verdicts, three tasks
✓Equipment · one line per instrument with interval, last calibrated, who, cost — due date, days and last result computed
✓Calibrations · every calibration with result, deviation found, cost, certificate number
✓Months · calibrations, fails, spend per month
✓Settings · warning window, tolerated failure rate
How it works
1Set the window — days of warning and the failure rate you tolerate — once
2List the instruments — one line each with interval and last date; the sample has a twelve-instrument workshop
3Open Monthly — overdue, coming, drift, three tasks — ten minutes
Who it is for

Workshops, labs, kitchens and small manufacturers with an audit coming and a calibration folder that is mostly hope.
