Maintenance and calibration
Keep your system ready for the next job.
A sensor, connection or panel fault can leave an operator without a clear reading. Plan inspections and repairs with documented findings, function checks and practical next steps.
- Scheduled checks and repairs
- Remote or site visits
Review
Current condition, failure history and priority assets.
Carry out the work
Agreed checks, adjustments or repairs.
Test
Function checks and recorded results.
Report
Findings, actions and the next priorities.
Follow the system from field to screen
The service plan identifies the assets, permitted work and expected records. Existing equipment is reviewed against documentation and device compatibility.
Instruments and panels
Inspect sensors, wiring, relays and actuators. Calibration or replacement is scoped to the instrument, reference method and site access.
PLC · SCADA
Review programs, alarms, operator screens and control sequences. Changes and backups follow the site's operating rules.
Servers and records
Check data storage, service status and backups. Record interruptions and actions required to restore missing data paths.
Communication links
Review device connectivity and telemetry. Remote checks require an available connection and access permitted by your team.
Choose the work your site needs
Scheduled maintenance
Agree inspection intervals, cleaning and checks around asset condition and operating windows.
Fault diagnosis and repair
Identify the fault, document findings and determine repair or replacement needs before proceeding.
Upgrades and function checks
Review firmware, panels and communication changes. Test the agreed functions before returning equipment to use.
Results and follow-up
A report you can act on
What is recorded
- Equipment checked and conditions found
- Work completed and function-test results
- Outstanding issues, parts and recommended follow-up
Agree the boundaries first
Site access, operating windows, spare parts, response arrangements and service targets are agreed in the proposal. These depend on the equipment and service agreement.
Make an informed choice
Restore a useful system, then keep it useful
Maintenance begins with the symptom and the equipment, not a promise to replace everything. Share what changed, when the problem started and what the team has already checked. The aim is to define a safe, practical scope for inspection, fault investigation and verified follow-up.
Describe the problem before choosing the work
A missing reading may come from the sensor, power, wiring, network or display. An unexpected value is not always a failed sensor. Provide alarm history, screenshots and recent changes so the inspection can be targeted. Avoid changing control settings or removing parts without the site's approved procedure and a record of the original configuration.
Separate checking, repair and calibration
A function check confirms whether a part works as expected. Calibration compares a measurement with a suitable reference under a defined method. Repair or replacement is a separate decision after findings are reviewed. Ask whether the proposed work includes field visits, reference equipment, parts, software changes and any certificate you specifically require.
Agree access and interruptions before the visit
Equipment models, drawings, passwords through an approved secure process, and available program backups help avoid unnecessary delays. Work on an operating plant needs permission, safe isolation where required and a suitable downtime window. Confirm which brands and models can be serviced, availability of parts and any limits on access to third-party programs or licences.
Ask for findings you can act on
Agree a report showing the condition found, work carried out, test results and remaining issues. A successful visit should leave the team clear about what has been restored and what still needs approval. Ask for the next check schedule and backup updates. Response time, remote support, warranty on work and repeat visits must be stated in the service agreement.
Questions before you buy
Can you service equipment from another supplier?
Share the brand, model and documentation. Capability, program access and available parts must be assessed before accepting the scope.
Does inspection include replacement parts?
Do not assume that. Separate inspection, parts and repair approval in the quotation.
Does calibration include an accredited certificate?
Confirm the required certificate, method and provider. A field function check is not automatically accredited calibration.
Can a problem be fixed remotely?
Some checks may be possible with authorised access. Physical faults, safety checks and site tests can still require a visit.
How quickly will someone arrive?
Confirm coverage, scheduling and the agreed response time for your location. No fixed arrival promise applies to every request.
What should we receive after the work?
Agree findings, actions, test records, updated backups where relevant and a clear list of unresolved items.
