A plan and a record, not a calculator
- The file does no study maths and holds no acceptance limits. You write your own rule (your customer's or your plant's) and the result you recorded.
- Run the study itself in your own study sheet or in our Gage R&R calculator, then put the file name in Report ref.
- The gauge calibration log tracks calibration due dates per gauge. This file tracks the separate studies of the measurement system.
What is in the file
- Settings: an as-of date (blank means today).
- Log: study ref, gauge ID, characteristic measured, study type (Repeatability and reproducibility, Attribute agreement, Bias, Linearity, Stability, Other), owner, planned date, study date, your acceptance rule, result recorded, outcome (Meets your rule, Does not meet your rule), action or 8D ref, report ref, next study due, notes.
- A separate check column. The status never hides it, and a row can show several notes, joined with a semicolon.
- Counts under the log: rows logged, rows per status, rows with a check note, rows past due (any status), a line that should read 0 (rows not in any status), rows per study type and rows per outcome. No score and no ranking.
How the status is worked out
In this order; the first match wins. A row only reads Done when every step before it is filled:
| Status | When |
|---|---|
| Enter study ref | The row has an entry but no study ref. It still counts. |
| Enter gauge ID | Gauge ID is blank. |
| Enter characteristic | Characteristic measured is blank. |
| Enter study type | Study type is blank. |
| Enter owner | Owner is blank. |
| Enter planned date | Planned date is blank. |
| Study past due | No study date, result, outcome or report, and the as-of date is after the planned date. |
| Planned | Not done yet. |
| Enter study date | A result, outcome or report is entered, the study date is blank. |
| Enter your acceptance rule | Your acceptance rule is blank. |
| Enter result | Result recorded is blank. |
| Enter outcome | Outcome is blank. |
| Enter action or 8D ref | Outcome is Does not meet your rule, action or 8D ref is blank. |
| Enter report ref | Report ref is blank. |
| Enter next study due | Next study due is blank. |
| Next study past due | The as-of date is after the next study due date. |
| Done, does not meet your rule | Every step above is filled, outcome Does not meet your rule. |
| Done | Every step above is filled, outcome Meets your rule. |
Check column notes, each followed by "worth a check", on any row whatever its status:
- Study past due, not done
- Done after the planned date
- Result, outcome or report entered, study date blank
- Outcome entered, result blank
- Result entered, acceptance rule blank
- Study date after the as-of date
- Next study due not after the study date
- Next study past due
- Does not meet your rule, action or 8D ref blank
- Planned date blank

|---|---|---|---|---|---|---|---|---|
| M-01 | G-101 | Repeatability and reproducibility | Mon 12 Oct 2026 | Wed 14 Oct 2026 | Meets your rule | Mon 12 Apr 2027 | Done | Done after the planned date: worth a check |
| M-02 | G-102 | Bias | Tue 20 Oct 2026 | Study past due | Study past due, not done: worth a check | |||
| M-03 | G-103 | Attribute agreement | Thu 29 Oct 2026 | Planned | ||||
| M-04 | G-104 | Stability | Thu 15 Oct 2026 | Enter study date | Result, outcome or report entered, study date blank: worth a check | |||
| M-05 | G-105 | Linearity | Tue 13 Oct 2026 | Tue 13 Oct 2026 | Does not meet your rule | Wed 13 Jan 2027 | Enter action or 8D ref | Does not meet your rule, action or 8D ref blank: worth a check |
| M-06 | G-106 | Repeatability and reproducibility | Tue 13 Oct 2026 | Fri 16 Oct 2026 | Does not meet your rule | Fri 15 Jan 2027 | Done, does not meet your rule | Done after the planned date: worth a check |
| G-107 | Stability | Fri 9 Oct 2026 | Enter study ref | Study past due, not done: worth a check | ||||
| M-08 | G-108 | Bias | Tue 14 Apr 2026 | Tue 14 Apr 2026 | Meets your rule | Fri 16 Oct 2026 | Next study past due | Next study past due: worth a check |
| M-09 | G-109 | Repeatability and reproducibility | Mon 19 Oct 2026 | Mon 19 Oct 2026 | Enter your acceptance rule | Result entered, acceptance rule blank: worth a check | ||
| M-10 | G-110 | Bias | Mon 26 Oct 2026 | Enter owner |
Worth a check each month
- Studies past due and next studies past due (marked in red).
- Results with no acceptance rule written next to them.
- Outcomes that do not meet your rule with no action or 8D ref.
The outcome is what you recorded against your own rule. The file does not judge whether a rule or a result is right; see Gage R&R and MSA basics.
