Choosing calibration software

Calibration tracking in Excel or Access: when it works and when it breaks

7 min read Published

Ask quality people what they use to track calibration and the most common answer is a spreadsheet. The second is a database someone built in Microsoft Access. That is not a mistake. A well-kept sheet tracks due dates for a few dozen gauges at no cost, and ISO 9001 does not require software. This guide is for the point where it stops being enough. It covers how to tell you have reached it, what actually breaks, and how to move without buying something expensive.

When a spreadsheet is the right answer

A spreadsheet works when the program is small and one person owns it. If you have a few dozen instruments, one person who logs every calibration, and an auditor who is satisfied with what you show, there is no reason to change.

The standards ask for records, not for a particular tool. ISO 9001 clause 7.1.5 wants your measuring equipment calibrated or verified at intervals, identified with its status, and protected from adjustments that would invalidate the results. A controlled spreadsheet can meet that.

Tip: If you stay on a spreadsheet, give it one owner, lock the formula columns, keep a dated backup each month, and store the certificate file name in the row so the record and the proof stay linked.

Five ways a spreadsheet or Access database breaks

These are the failure points quality and metrology people describe most often once a program grows. You do not need all five for it to be time to move. One or two that keep recurring is usually enough.

  • The person who built it leaves. The formulas, the macros and the reasons behind them leave too, and whoever inherits it is afraid to touch it.
  • Nobody else can see it. The file sits on one drive, so people ask the owner whether a gauge is available or in calibration instead of looking it up.
  • Recall depends on someone remembering to look. A sheet does not send a reminder, so a due date that nobody filtered for becomes an overdue gauge still in use.
  • History gets overwritten. Editing a cell replaces what it said, and an auditor asking what the record showed last year gets a guess.
  • Certificates live somewhere else. The PDFs are in a folder, the row points at a file name, and after a server move the link points at nothing.

Why Access databases are a special case

Access is more capable than a spreadsheet, and people who build calibration databases in it are often proud of them with good reason. It handles recall reports, linked procedures and history far better than Excel.

The trade-off is that it is a desktop file. It lives on one computer or a shared drive, phones and web browsers cannot reach it without extra work, and it depends on the person who built it. When that person leaves, the program usually goes with them. If your Access database is working and well documented, keep it. If it is the file nobody dares open, it is time.

What moving costs, and why it can be nothing

Cost is the main reason shops stay on spreadsheets. Several established calibration packages price per user or per installed PC, charge an annual maintenance fee on top, or do not publish prices at all. For a small team that can add up to thousands of dollars a year before anyone has logged a calibration.

Axiospec is priced the other way. It is free for up to 50 active instruments, permanently, with unlimited users. Above that, plans are one flat monthly price per workspace: $59, $129, $229 or $399 depending on how many instruments you track. There are no per-user fees, no per-PC licenses and no maintenance charge, and every price is on the pricing page.

Moving your spreadsheet over

You can do the move yourself in an afternoon, or hand it to us.

  1. Save a copy of your spreadsheet as it is today, and keep it untouched.
  2. Create a free account and import the file. Axiospec reads CSV and Excel files and maps your columns for you.
  3. Rows with missing or odd values still come in, with a warning that says what to fix. Only rows with no ID, no name or a duplicate ID are held back for you to correct.
  4. Check the imported list and due dates against your spreadsheet, then log new calibrations in Axiospec from that day on.
Tip: If you would rather not do any of it, click "Send us your files" in the app and upload what you have, spreadsheet or Access export. We load it for you, free, usually within a couple of business days.

What you get that a spreadsheet cannot do

  • Due-date reminder emails to the people you choose, so recall does not depend on someone remembering to filter a column.
  • Everyone on the team can look an instrument up from a browser or the iOS and Android apps, with no per-user charge.
  • QR labels you print from the app. Scanning one on the floor opens that instrument's record.
  • A tamper-evident history. Each calibration is added to a hash-chained record you can verify in one click, so last year's entry cannot be quietly changed.
  • Certificates attached to the instrument they belong to, and an audit pack you can export for one gauge or the whole register.
  • A read-only login for your auditor, so they can look for themselves.

Support and feature requests

Support is by email, answered by the people who build Axiospec, not a ticket queue. If it does not do something you need, tell us. We build what users ask for, and you will hear back from the person who would build it.

Common questions

Is Excel good enough for calibration tracking?
For a small program with one owner, yes. ISO 9001 asks for calibration records, status identification and defined intervals, not for software. Excel stops being enough when several people need to see the records, recalls start slipping because nobody filtered for due dates, or an auditor asks what a record said before it was edited.
Can I use Microsoft Access to manage calibration?
Yes, and many shops do. Access handles recall reports and history better than a spreadsheet. Its weak points are that it is a desktop file, phones and browsers cannot reach it easily, and it usually depends on the one person who built it.
How do I move my calibration spreadsheet into software?
In Axiospec you import the CSV or Excel file and the columns are mapped for you, or you upload the file with "Send us your files" and the team loads it for free, usually within a couple of business days.
How much does calibration software cost?
It varies widely. Some packages charge per user or per installed PC plus annual maintenance, and many do not publish prices. Axiospec is free for up to 50 active instruments with unlimited users, and above that costs a flat $59, $129, $229 or $399 per month per workspace.
Does ISO 9001 require calibration management software?
No. Clause 7.1.5 requires that measuring equipment is calibrated or verified at specified intervals, identified with its status and safeguarded. A controlled spreadsheet can meet that. Software makes it easier to keep meeting it as the program grows.

Put it into practice

Got a gage list? Send it over and we load it for you, usually in a couple of business days. Free on every plan. Then log every calibration to a tamper-evident audit trail and produce records on demand.
