Medical equipment calibration in Australia is an important consideration when healthcare facilities use loan or replacement devices. A temporary monitor, infusion pump or blood pressure device may help maintain services while the usual equipment is being repaired, but its measurement performance and suitability still need to be assessed.
Equipment arriving from a supplier, another department or an external service provider may have a different service history, configuration or set of accessories. Familiar appearance does not establish that it is ready for clinical use.
A structured process for receiving, checking, approving and tracking temporary equipment helps healthcare facilities maintain clear records and manage measurement reliability throughout the loan period.
What Is Loan and Replacement Medical Equipment?
Loan medical equipment is supplied temporarily for an agreed period. Replacement equipment may be provided while an existing device undergoes calibration, maintenance or repair, or while a permanent replacement is being arranged.
Common situations include:
- A supplier providing a temporary device during servicing.
• A hospital borrowing equipment from another facility.
• A clinic hiring additional equipment during increased demand.
• A manufacturer providing a demonstration unit for evaluation.
• A department receiving a replacement after equipment failure.
Although ownership may remain with another organisation, the receiving facility should establish how the equipment will be assessed and authorised before use.
Why Is Calibration Important for Temporary Medical Equipment?
Calibration compares a device’s measurement performance with suitable reference standards under specified conditions.
For medical equipment, this can provide evidence about measurement errors across relevant operating points. Results must then be assessed against appropriate acceptance criteria.
Calibration does not automatically include adjustment, repair, electrical safety testing or a complete assessment of clinical suitability.
The TGA’s Essential Principles guidance identifies calibration, maintenance and servicing information as part of the information manufacturers must provide where applicable. Manufacturer instructions should therefore inform the assessment of temporary equipment.
Key Benefits:
- Measurement Confidence: Relevant results help assess whether a device performs within the required limits.
- Clear Equipment Identity: Matching records to serial numbers reduces confusion between similar devices.
- Service Continuity: Planning equipment checks helps avoid delays when the usual device becomes unavailable.
- Documented Decisions: Records show who reviewed the equipment and authorised its use.
- Better Follow-Up: Tracking faults, service dates and location supports management throughout the loan period.
What Should Be Checked Before Loan Equipment Is Used?
The following workflow provides a practical equipment-management approach. The exact checks should reflect the device, manufacturer instructions, clinical risks and facility procedures.
1. Confirm the Equipment’s Identity
Record the details of the actual device received.
Include:
- Manufacturer and model.
• Serial number.
• Supplier or equipment owner.
• Temporary asset number, where used.
• Receiving department and location.
• Arrival date and expected return date.
• Supplied accessories and their identifiers, where relevant.
Do not rely on a delivery description such as “patient monitor” when several similar devices may be circulating.
A calibration certificate for another unit of the same model does not establish the performance of the device received.
2. Review Calibration and Service Records
Request the documentation relevant to the equipment and intended application.
Depending on the device, this may include:
- Calibration results.
• Preventive maintenance records.
• Repair and adjustment details.
• Functional test reports.
• Relevant electrical safety test results.
• Manufacturer instructions.
• Information about outstanding faults or restrictions.
A service label can help identify status, but it may not provide enough information to assess the work performed.
Check that supporting records match the equipment’s serial number and describe the relevant tests.
3. Check Whether the Calibration Covers the Intended Use
A calibration report may cover only selected functions or measurement ranges.
For example, a multifunction monitor may have several measurement channels, while the supplied documentation addresses only one.
Review:
- Functions tested.
• Measurement ranges and test points.
• Recorded errors.
• Measurement uncertainty, where applicable.
• Acceptance criteria and any conformity statement.
• Limitations or exclusions.
• Accessories included in the assessment.
A certificate should be evaluated against how the equipment will actually be used.
4. Inspect the Device After Transport
Transport and handling can introduce problems that were not present during an earlier service.
Inspect for:
- Cracked housings or damaged displays.
• Loose connectors.
• Damaged cables and power supplies.
• Missing accessories.
• Signs of fluid ingress.
• Damaged packaging or evidence of impact.
Follow the manufacturer’s transport, storage and handling instructions. TGA guidance states that medical devices must be designed to withstand transport and storage without adverse effects when those instructions are followed.
If damage or uncertain performance is identified, refer the device for assessment before release.
5. Verify Accessories and Configuration
The supplied accessories should be suitable for the exact device and intended application.
Check relevant items such as:
- Blood pressure cuffs and hoses.
• Temperature probes.
• Patient cables and sensors.
• Power supplies and battery packs.
• Infusion-related accessories.
• Network connections and software configuration.
An accessory that physically connects is not necessarily compatible.
Where accessories affect measurement performance, confirm whether the calibration or verification covered the relevant combination.
6. Complete Appropriate Acceptance Checks
Acceptance checks help establish whether the received equipment is ready for its intended use.
Depending on the device and facility procedures, these may include:
- Reviewing documentation.
• Inspecting physical condition.
• Performing functional checks.
• Checking relevant measurement performance.
• Assessing alarms and battery operation.
• Completing applicable electrical safety testing.
• Confirming cleaning or decontamination status.
Competent personnel should determine the required checks. A successful power-on test alone does not establish readiness for clinical use.
Does Every Loan Device Need Recalibration on Arrival?
Recalibration should not be assumed necessary solely because equipment is on loan. Equally, temporary ownership arrangements do not remove the need to establish acceptable performance.
The decision should consider:
- Manufacturer instructions.
• Availability and relevance of existing results.
• Equipment condition on arrival.
• Transport or damage concerns.
• Repairs or adjustments since the last calibration.
• Intended measurement ranges.
• Facility acceptance procedures.
• Applicable contractual or accreditation requirements.
If records are missing, results are unsuitable or receipt checks raise concerns, further assessment may be needed before use.
Who Is Responsible for Loan Equipment?
Responsibilities should be agreed before the equipment enters service.
The arrangement should identify who will:
- Supply calibration and maintenance records.
- Complete receipt and acceptance checks.
- Authorise clinical use.
- Track equipment location.
- Monitor service and calibration dates.
- Arrange repairs or replacement.
- Receive fault and incident reports.
- Coordinate cleaning and return.
The supplier may maintain the equipment, while the healthcare facility manages local acceptance and use. These arrangements should be explicit rather than assumed.
How Should Calibration Dates Be Managed During the Loan?
Temporary equipment can remain in use longer than originally planned. A short loan may be extended while repairs or procurement continue.
Record relevant due dates in the facility’s tracking system and compare them with the expected loan period.
Useful practices include:
- Setting reminders before scheduled servicing.
• Confirming who will arrange the work.
• Reviewing status before extending a loan.
• Planning alternative equipment if the device must be withdrawn.
• Recording changes to the agreed arrangements.
Receiving a device does not restart its calibration interval. Changing ownership, location or asset number also does not create new evidence of measurement performance.
What If Calibration Documents Are Missing?
Missing documentation creates uncertainty about the equipment’s status.
A practical response is to:
1. Request Records for the Exact Device
Ask the supplier for documentation matching the serial number, relevant functions and supplied accessories.
2. Clarify What Has Been Completed
Establish whether the equipment underwent calibration, maintenance, functional testing or another service. These activities provide different information.
3. Refer the Device for Technical Review
Ask the responsible biomedical engineering team or competent service provider to determine what further assessment is needed.
4. Record the Release Decision
Document the evidence reviewed, any restrictions and the person authorising use.
Where suitability remains unresolved, follow the facility’s process for restricting equipment use and arranging an alternative.
What Happens If Loan Equipment Fails a Check?
A failed check should trigger a documented investigation.
Record:
- Device identity and location.
• Date and nature of the failure.
• Test conditions and results.
• Accessories and settings involved.
• Whether the device had already been used.
• Actions taken and people notified.
Control further use according to facility procedures and contact the equipment owner or service provider.
If the equipment was already in service, the responsible clinical and technical teams should assess whether previous measurements or care decisions could have been affected.
Retaining results before adjustment or repair can help that investigation.
Managing the Return of the Original Equipment
The original device should undergo an appropriate return-to-service review after calibration, repair or maintenance.
Check:
- Work completed.
• Results before and after adjustment, where available.
• Components or accessories replaced.
• Remaining limitations.
• Changes to settings or software.
• Relevant acceptance checks.
• Updated service and calibration status.
A replacement device’s satisfactory performance does not establish that the original equipment is ready to return.
Update the equipment register so staff can identify which device is authorised and where it is located.
Returning Loan Equipment to the Supplier
A clear return process helps prevent missing accessories, incomplete records and unresolved faults.
Before dispatch:
- Confirm the device’s serial number.
• Reconcile supplied accessories.
• Record faults, damage or unusual behaviour.
• Complete required cleaning or decontamination procedures.
• Manage stored patient information through authorised procedures.
• Package the equipment according to manufacturer instructions.
• Record the return date and receiving organisation.
Do not perform an unapproved factory reset, as this may alter configurations or remove information needed for investigation.
Choosing a Medical Equipment Calibration Provider in Australia
Choose a provider whose technical capabilities match the device and required measurements.
Consider:
- Experience with the equipment type.
• Relevant measurement ranges and uncertainty.
• Appropriate reference standards and traceability.
• Clear reporting and instrument identification.
• Availability of results before adjustment.
• Turnaround and on-site service options.
• Ability to explain limitations and exclusions.
Where NATA-accredited calibration is required, check the provider’s scope for the specific activity. NATA accreditation relates to defined capabilities, and its directory allows users to search accredited organisations and their scopes.
Common Mistakes to Avoid
Loan and replacement equipment can become difficult to manage when temporary arrangements bypass normal controls.
Common mistakes include:
- Accepting a certificate for the wrong serial number.
• Assuming a maintenance visit included calibration.
• Treating a calibration label as complete evidence.
• Overlooking accessories that affect measurements.
• Using equipment before acceptance checks are complete.
• Failing to track an extended loan.
• Returning equipment without reporting faults.
• Releasing the repaired original device without reviewing its results.
A consistent receiving and approval process helps reduce these gaps.
Final Thoughts
Loan and replacement medical equipment can help Australian healthcare facilities maintain services during repairs, maintenance and calibration.
Reliable management starts with identifying the exact device, reviewing relevant records, checking its condition and documenting approval before use. Tracking responsibilities, location and service dates remains important throughout the loan.
Temporary equipment should have a clear assessment and equipment history that supports its intended clinical application.
