Automation · Test equipment management and calibration

An overdue measuring instrument must never leave the cabinet in the first place.

Automating test equipment management means: every measuring instrument has its own inspection deadline, the reminder arrives weeks before it expires, and anyone trying to issue an expired instrument sees the block on their phone. We assign calibration certificates from the external calibration body to the measuring instrument automatically, together with the new due date. We build this into the systems you already have, and we tell you honestly if your stock of test equipment needs a purchased test equipment management system instead.

The problem

The auditor asks which measuring instrument was used to inspect this batch, and the room falls silent.

The test equipment list sits in Excel, maintained by one person, opened by no one. As long as no auditor and no customer asks, nobody notices that three calipers have been past their calibration interval for a year and are still used every day.

  • 01Calibration intervals sit in an Excel sheet whose due-date column no one sorts, and the deadline is only noticed once the sticker has already expired.
  • 02An overdue measuring instrument lies in the same drawer as the valid ones: technically there is nothing to stop the worker from carrying on measuring with it.
  • 03Calibration certificates arrive as PDFs by email from the calibration body, land in the quality manager's inbox and, two years later, are no longer anyone's responsibility.
  • 04Who currently has which measuring instrument is known only to whoever last saw it: before dispatch for calibration, half the early shift goes searching.
Use cases
01

What we automate specifically in test equipment management.

Five processes we build again and again in production, quality assurance and test laboratories. Your stock of measuring instruments, your calibration body and your ERP stay in place; only the list disappears.

01

An inspection deadline per measuring instrument instead of one shared interval for all

Every measuring instrument gets its own record with an inventory number, location, inspection deadline and next due date. The caliper in series production runs on a shorter interval than the micrometer set in the prototype shop that is touched three times a year, because the deadline depends on use and risk, not on the calendar. You set the intervals; we make sure the reminder reaches the responsible person 30 to 60 days beforehand and not on the due date.

Effect No calibration deadline expires unnoticed
02

Overdue measuring instruments are blocked, not just flagged

When the deadline expires, the measuring instrument automatically switches to the blocked status and issuing is refused: anyone who scans the QR code on the caliper gets a red warning instead of a receipt. This is the point at which a notice and a sticker regularly fail, because both rely on someone looking. The quality manager can lift a block with a documented reason, and this is logged so that in the audit it remains explainable who decided what and when.

Effect An expired measuring instrument never reaches anyone's hands
03

The calibration certificate comes in and files itself

The calibration certificate from the external calibration body arrives as a PDF by email and, instead of getting lost in the inbox, is filed with the measuring instrument. We read out the inventory number, calibration date and result, attach the document to the record and set the next due date. If a certificate arrives for a number that does not exist in your system, or shows a result outside tolerance, the case goes to a person instead of passing through silently.

Saving under 1 min. instead of a folder and an inbox
04

Batch dispatch to the calibration body with a delivery note and a replacement plan

From the measuring instruments due in the next quarter, one collective order is created instead of twelve individual shipments over the year. The system generates the delivery note, reports which measuring instruments are away at the same time, and points out the spots where no replacement device is then left on site. How long your calibration body takes, you know better than we do, so you set the lead time and we build it in.

Effect No measuring station stands idle because of dispatch
05

Issue, return and history for each measuring instrument

Issue and return run via a scan on the measuring instrument: who has it, since when, at which workstation. This produces, as a by-product, the history you need in the audit, with every calibration, every result and every user on the record. The real value shows when a measuring instrument fails calibration: you then see within minutes who has used it since the last valid calibration and which inspections were run with it, instead of reconstructing that from shift logs.

Effect A history for each measuring instrument in one minute
Tools

What we build your test equipment monitoring with.

Which tool fits depends on your stock and on what your quality assurance works with today: 80 measuring instruments at one site are a different task from 900 across four. We commit after the as-is assessment, not according to a partner programme, and we do not sell you a tool just because we happen to be good at it right now.

Data hub
n8n

Takes calibration certificates from the inbox, calculates due dates, applies blocks and notifies the quality manager. On request it runs on a server in your own building, so that inspection results and calibration data do not leave the plant.

Power Platform

If you already work in Microsoft 365, issuing at the measuring equipment cabinet becomes a Power App on the phone and deadline monitoring a Power Automate flow. Accessing an on-premises ERP requires the On-premises Data Gateway, and this gateway as well as custom connectors are licence-bound entitlements. We work out the cost with you before implementation, not afterwards.

Legacy system without an interface
UiPath

Some QM and test equipment modules in older ERP or industry-specific systems have no interface, and the vendor no longer builds one. In that case a software robot enters calibration data and due dates the way a person would type them, only without transposed digits in the inventory number. This is the bridge when a system change is not on the agenda right now.

How we work

The 30-day model.

We work at a fixed price instead of an open-ended timesheet. After the initial analysis you know what it costs before we start.

1

Initial analysis of your stock of measuring instruments (free)

In 60 minutes we walk through your current process: which measuring instruments, which intervals, which calibration body, who issues and who monitors. After that, both sides know whether automation is enough or whether your stock deserves a purchased test equipment management system.

2

Define the test equipment master data and deadlines, fixed price

Together with you we determine which measuring instrument gets which deadline, which requires monitoring and which runs as a mere aid. Fewer categories are almost always better, because they actually get followed during the shift. You receive a quote with a fixed price and a fixed scope.

3

Pilot on one group of measuring instruments, running in parallel against the list

We start with one group, usually the hand-held measuring instruments of a production line, and keep the old Excel list running alongside for a few weeks. Only once both sides show the same due dates do we roll out to the rest of the stock.

4

Handover with an audit trail

You receive documentation, a briefing for quality assurance and workers, and an audit trail: for every block, every release and every calibration certificate it is traceable who or what triggered it. You stay in control, and on request we stay on board for ongoing support.

Around production

Test equipment is rarely the only list someone maintains by hand.

Once the calibration deadlines report on their own, you notice that alongside them the maintenance of your equipment still runs on the same logic: an Excel sheet and a good memory. On the maintenance page you can see how we automate maintenance schedules and statutory inspection deadlines for equipment.

Free initial analysis

Do you know off the top of your head how many of your measuring instruments are currently past their deadline?

In the free initial analysis we go through your stock of test equipment and take a look: 60 minutes, no obligation, with an honest assessment. If an off-the-shelf test equipment management system is the better choice for you, we say so, even if that means we build nothing.

Frequently asked questions
05

What quality managers often ask.

How often must test equipment be calibrated?

No one prescribes a fixed interval for all measuring equipment. ISO 9001:2015 requires in section 7.1.5.2 that measuring equipment be calibrated or verified at defined intervals or before use, but it names no figure. You set the interval yourself, depending on frequency of use, stress, measurement uncertainty and on what an incorrect measurement result would cause in your operation. You will find reference values in the manufacturer's specifications and in relevant guidelines such as VDI/VDE/DGQ 2618 or DIN 32937. We do not name an interval for you; we make sure that the one you have defined does not slip through.

What exactly does ISO 9001 chapter 7.1.5 require for test equipment?

Section 7.1.5 of ISO 9001:2015 is titled Monitoring and measuring resources and requires you to provide and maintain suitable measuring equipment. Subsection 7.1.5.2 on measurement traceability becomes more specific: measuring equipment must be calibrated or verified at defined intervals against international or national standards, be clearly identified so that its calibration status is recognisable, and be protected against adjustment, damage and deterioration. You must also retain documented information as evidence of fitness for purpose, and that is exactly what the calibration certificate is. What these requirements mean in practice is a data-maintenance task, and that can be automated.

What happens if a measuring instrument fails calibration?

Then it is not enough to take the measuring instrument out of service: ISO 9001:2015 requires in 7.1.5.2 that you determine whether measurement results obtained with it earlier are still valid, and respond appropriately. In practice this means you must know retrospectively which parts or batches have been inspected with this measuring instrument since the last valid calibration, and, in case of doubt, inform the customer or re-measure. Without a clean issue and inspection history, this becomes a reconstruction from shift logs and memory, and that reconstruction costs more than the automation that records the connection from the outset.

Do we need dedicated test equipment management software for this?

Not necessarily, but beyond a certain size yes, and if so, we will tell you. With 50 to 300 measuring instruments, manageable intervals and external calibration, we automate deadlines, blocks, calibration certificates and issuing cleanly into your existing systems, without you having to introduce and maintain another piece of software. If, on the other hand, you run measurement system analyses using methods such as MSA, your own calibration with a measurement uncertainty budget, or an accredited laboratory in accordance with ISO/IEC 17025, you are better off buying a mature test equipment management system or the QM module of your ERP. In that case we help with selection and integration rather than selling you a rebuild that will hit its limits in three years.

Does this replace our external calibration body?

No, calibration must still be carried out by a suitably qualified body, and for traceable calibration this is, as a rule, an accredited laboratory or your in-house calibration service. No automation changes that, and we make no claims to the contrary here. What we automate is everything around it: due-date monitoring, batch dispatch with a delivery note, the return of the calibration certificate including its assignment to the measuring instrument, and release after it comes back. The calibration body provides traceability to national standards; we make sure that its certificate does not disappear into an email inbox.
