Calibration Checks & Performance Verification on the Devices Your Clinicians Rely On
PBES verifies that medical equipment performs within expected parameters — running applicable calibration checks and performance tests against manufacturer guidance and reference standards, with measured results documented per device.
- Measured results, not pass/fail guesses
- Checks matched to the device and manufacturer guidance
- Per-device records in TESSA
- Findings routed to repair when out of spec
Not every device requires formal calibration. The checks performed depend on equipment type, manufacturer service information, applicable standards, and facility policy — and every result is recorded with the measured value.

At a glance
A quick summary of this service.
The problem
A device that powers on is not the same as a device that performs to spec.
Equipment can look operational but drift out of its expected range over time — a monitor that reads slightly high, a pump that delivers marginally off rate, a defibrillator with low output. Without measured verification, those issues stay hidden until they affect a patient or a survey.
Facilities also need the record, not just the check. An administrator or surveyor wants to see what was tested, what the measured value was, what standard or reference it was checked against, and whether it passed.
PBES runs calibration checks and performance verification appropriate to the device, and documents the measured results — so the record reflects what was actually verified.
Common issues
What calibration & performance verification may include
Scope is determined by equipment type, manufacturer guidance, and the service agreement. Not every check applies to every device.
Functional performance verification
Confirms the device operates within expected parameters for its intended use.
Calibration checks
Where applicable, verification against a reference standard or known input.
Vital-signs accuracy
NIBP, SpO2, and temperature against a reference where supported.
Flow-rate verification
Infusion pump delivery accuracy checked against a measured reference.
Temperature verification
Refrigerator, freezer, and autoclave temperature against a calibrated probe.
Speed / timer verification
Centrifuge RPM and timer checked against a measured reference.
Output verification
Defibrillator energy and ESU output checked where applicable.
Alarm verification
Patient-monitor and device alarms confirmed to trigger at set limits.
Battery & power verification
Battery capacity and power-condition checks on portable devices.
Measured-result documentation
Every check recorded with the measured value and pass/fail outcome.
Our approach
How PBES handles every service visit.
A disciplined sequence, delivered the same way on every device — so your team gets consistent service and consistent documentation through TESSA.
- Step 01
Confirm device & service scope
Identify make, model, serial, and the manufacturer guidance that applies to this device.
- Step 02
Determine applicable checks
Select the calibration checks and performance tests appropriate to the equipment type and applied parts.
- Step 03
Verify against reference
Run the checks against a reference standard or known input where applicable.
- Step 04
Record measured results
Capture the measured value and pass/fail outcome for each check.
- Step 05
Flag out-of-spec findings
Any result outside expected range routes to a repair recommendation with clear next steps.
- Step 06
Document in TESSA
Per-device verification record with measured results, ready for an administrator or surveyor.
TESSA · The PBES advantage
Every verification recorded with the measured value.
TESSA keeps the verification history on the asset — what was checked, the reference used, the measured result, and the next-due — so administrators can see the actual condition of the fleet, not just a pass mark.
TESSA — Technical Equipment Support and Service Assistant — is how PBES organizes equipment records, service history, PM status, and repair follow-up for the facilities we serve.
- Per-device verification record with measured results
- Reference standard and check performed
- Pass/fail outcome and out-of-spec flags
- Service history alongside PM and ESI records
- Next-due visibility for planning
- Multi-site rollups for fleet condition
Documentation

Frequently asked questions.
What's the difference between calibration and performance verification?
Performance verification confirms a device operates within expected parameters for its intended use. Calibration checks verify measured accuracy against a reference standard or known input. Not every device requires formal calibration; the applicable checks depend on the equipment type and manufacturer guidance.
Do all medical devices need calibration?
No. Whether a device requires calibration checks depends on its type, function, manufacturer service information, and facility policy. PBES determines the applicable checks based on the equipment rather than applying a universal test to every device.
How often should calibration and performance verification be performed?
Frequency should follow manufacturer guidance, the device's use, and facility policy. Many devices are verified as part of an annual PM, but specific intervals depend on the equipment and how heavily it is used.
What standards or guidance does PBES follow?
PBES performs checks based on manufacturer service information and applicable standards for the equipment type. We document what was checked, the reference used, and the measured result rather than applying a single universal protocol.
Are the results traceable and documented?
Yes. Each check is recorded with the measured value, the reference standard or input used, and a pass/fail outcome. Records are organized per device in TESSA and can be handed to an administrator or surveyor.
Can PBES verify [a specific device]?
PBES supports many common patient-care and diagnostic devices. Specific capabilities depend on make, model, parts, and available references — contact us with the equipment and we'll confirm what verification applies.
What happens if a device fails verification?
Any out-of-spec result is flagged in TESSA and routed to a repair recommendation with clear next steps, so the finding is documented and acted on rather than left unresolved.
