Passed the calibration.
Out of tolerance for six months.
A calibration system that knows the difference, and produces the record your auditor asks for.
Or email akhand.singh@akhandnow.com directly.
As-found readings from a 0–16 bar transmitter on a ±0.5% tolerance. Adjusted, it passes. The pack flags that it was found out of tolerance and opens an investigation.
The gap most plants have
Calibration records get kept. What usually goes missing is everything around them: which instrument is overdue today, what a failed instrument was reading before someone adjusted it, and which batches it measured in the meantime.
That last one is where audits go wrong. A technician who adjusts an instrument before recording its as-found readings destroys the only evidence of whether the previous six months of production data were valid — and it cannot be reconstructed afterwards.
What you get
Two files. An Excel workbook that runs the system, and a written procedure that explains and governs it.
100 pre-built rows. Enter an instrument once; span, next due date, days remaining and status calculate themselves. Colour-coded, filterable, with dropdowns for type, criticality and interval.
Live counts of overdue, due soon and compliant instruments, a compliance rate, and overdue broken out by criticality. The screenshot for your management review.
A rolling view of how many calibrations fall due each month, and how many are critical. Reference standards counted separately, because they leave site for weeks and everything else schedules around them. Months with ten or more due are flagged.
Enter a tag number and the instrument details pull through automatically. Five-point check, as-found and as-left columns, error calculated as a percentage of span, pass or fail against that instrument's own tolerance.
Reduced single-point checks between full calibrations, to catch drift before it becomes an out-of-tolerance event. Also covers dial thermometers, local gauges and platform scales that don't warrant a full five-point certificate.
22 items from drawing verification through to stroking the final element. The summary will not read “accepted” until every item is closed.
Identification, deviation, impact assessment, root cause, immediate action, corrective action, close-out signatures.
Your calibrators, with their own due dates and traceability. If one expires, every calibration performed with it becomes questionable — this sheet tells you before that happens, on a 60-day warning because laboratory turnaround is slow.
Who is authorised to calibrate what, how they were assessed, and when they need reassessing. Auditors ask who is permitted to sign a certificate. This answers it.
25 questions covering the whole system, scored automatically. Work through it before your auditor does — a gap you find yourself costs nothing.
Nine pages covering scope, definitions, responsibilities, criticality classification, traceability, the calibration method, OOT control, loop checking and record retention. Supplied as a template you edit with your own site details.
The part free templates miss
Every calibration template judges pass or fail on the as-left readings — the values after adjustment. That is correct, and it is only half the job.
This one evaluates the as-found condition separately. If the instrument was found outside tolerance, the certificate says so in plain language and tells you an investigation is owed, even when the calibration itself passes.
A pasteuriser thermometer reading 2 °C high means the real process temperature was 2 °C lower than anyone believed. That is a food safety question. The same instrument reading 2 °C low means product was over-processed — a yield question, not a safety one. Same magnitude, different consequence, different response. The procedure requires you to state the direction every time.
What an auditor asks, and where the answer is
| Question | Where it is answered |
|---|---|
| Show me your list of critical instruments. | Register, filtered on criticality. |
| Is anything overdue right now? | Dashboard, broken down by criticality. |
| What was this one reading before you adjusted it? | As-found column on the certificate. |
| What standard did you use, and is it in date? | Certificate section 2 — calibrator identity and traceability date. |
| This one failed. What did you do about the product? | OOT record, impact assessment. |
| Why is this instrument on a 12-month interval? | Criticality classification, plus any documented interval change. |
Whether this fits
Built for
- Food, beverage, water and light manufacturing plants
- Sites preparing for ISO 9001, ISO 22000, FSSC 22000 or HACCP
- QA and maintenance managers running calibration on spreadsheets
- Anyone who has just been given an audit finding on calibration records
Not built for
- Sites already running a CMMS with a calibration module
- Accredited calibration laboratories working to ISO/IEC 17025
- Pharmaceutical GMP, which needs validated electronic records
- Anyone wanting software — this is Excel and a PDF, not an application

Questions
Does it work in Google Sheets?
It is built for Excel. Most of it survives an import to Sheets, but the conditional formatting and dropdowns need rebuilding. If Sheets is your only option, buy it expecting to spend an hour tidying up.
Can I put my own company name on it?
Yes. Both files are yours to edit and rebrand for use within your own organisation. You cannot resell or redistribute them as a product.
How many instruments does the register hold?
100 rows are pre-built with formulas. To add more, copy the last row down and the formulas follow.
Will this make us compliant?
No document makes you compliant — doing the work does. This gives you the system and the records to demonstrate it. The procedure is a template written against requirements common to ISO 9001, ISO 22000, FSSC 22000 and HACCP; check it against what your own certification body requires before you adopt it.
Is there a refund?
Yes. If it is not useful, reply to your receipt within 30 days and you get your money back. You keep the files.
