Calibration Workflow

A Structured Process From Instrument Review to Reporting

Each calibration assignment is reviewed according to the instrument type, measuring range, condition, required points, application and service location before technical work begins.

01

Instrument Information

The instrument name, manufacturer, model, serial number, range, resolution, quantity and calibration requirements are collected.

02

Initial Inspection

The instrument is checked for physical condition, readability, basic operation, accessories and suitability for calibration.

03

Calibration Execution

Measurements are performed at the planned calibration points using the selected method and suitable reference equipment.

04

Data Review

Recorded readings, indication error and available technical observations are reviewed before the result is finalized.

05

Certificate & Release

The calibration result is documented and the instrument is released with the applicable certificate or service record.

Service Arrangement

Laboratory and On-Site Calibration Support

The appropriate service arrangement depends on instrument portability, quantity, site conditions, operational requirements and the available technical method.

Laboratory Calibration

Suitable for portable instruments that can be received and calibrated under controlled service conditions.

On-Site Calibration

Considered for installed, heavy, sensitive or operationally critical equipment after technical review.

Preparing instruments for calibration Ensure the instrument is clean, identifiable, complete with required accessories and accompanied by the available service history or special calibration instructions.

Calibration Interval Guidance

How Should Calibration Frequency Be Decided?

Calibration frequency should not be selected only from a fixed calendar interval. It should consider instrument performance, application risk, manufacturer guidance, usage conditions and previous calibration results.

Usage Frequency

Frequently used instruments may require closer performance monitoring than rarely used equipment.

Process Criticality

Instruments affecting product quality, safety or compliance may require shorter review intervals.

Historical Stability

Previous calibration results can help identify drift and support interval adjustment decisions.

Working Conditions

Vibration, temperature, humidity, shock and harsh use may influence instrument performance.

When Should an Instrument Be Recalibrated?

Recalibration may be required before the normal planned date when an event could have affected instrument performance or measurement confidence.

After repair, adjustment or component replacement
Following impact, overload or abnormal operation
When readings appear unstable or inconsistent
Before use in a new critical application
After extended storage or prolonged non-use
When required by internal equipment procedures

Calibration FAQs

Common Questions About Instrument Calibration

These answers provide general guidance about quotations, instrument preparation, calibration points, service location and reporting.

Need a quotation for multiple instruments?

Send the instrument list with equipment name, model, serial number, measuring range, quantity and service location.

Submit Instrument List
What information is required for a calibration quotation?

Please provide the instrument name, manufacturer, model, serial number, measuring range, resolution, quantity, required calibration points, service location and any special reporting requirement. Clear equipment photographs may also help with technical review.

Can calibration be performed at the client’s site?

On-site calibration may be considered for installed, heavy, sensitive or operationally critical instruments. Availability depends on the instrument type, parameter, measuring range, site conditions and applicable calibration method.

How are calibration points selected?

Calibration points are selected according to the instrument range, normal operating range, critical process values, client requirements and the applicable calibration method. Specific points should be agreed before work begins.

Does calibration include instrument adjustment or repair?

Calibration determines and records instrument performance. Adjustment or repair is a separate activity and should only be carried out after client approval. Where adjustment is performed, recalibration may be required to confirm the final result.

What should be sent with the instrument?

Instruments should be clean, properly identified and supplied with the accessories required for operation. Available manuals, connection cables, probes, adapters, special fittings and previous service instructions should also be included where relevant.

How often should an instrument be calibrated?

Calibration frequency depends on instrument stability, usage, application risk, working conditions, manufacturer guidance, previous calibration results and the organization’s equipment-management procedure. A fixed interval may not be suitable for every instrument.

What happens when an instrument shows excessive error?

The observed result should be reviewed against the client’s acceptance criteria or process requirement. The instrument may require adjustment, repair, replacement or an assessment of measurements previously made using that instrument.

Can several instruments be included in one request?

Yes. For multiple instruments, share a spreadsheet containing equipment name, manufacturer, model, serial number, identification number, range, quantity and required service. This helps prepare an accurate technical and commercial response.
