Electrical Calibration
Describe the electrical functions, ranges and test points that need checking so a suitable calibration scope can be confirmed.
Overview
Electrical calibration compares an instrument’s measurements or outputs with suitable reference values. Voltage, current, resistance and frequency are different quantities, and AC and DC functions need to be identified separately. The functions and operating points used in your work are more informative than a model name alone.
For a multimeter, source or other electrical instrument, provide the relevant manual and the measurements you need assessed. Calibration can be requested without adjustment; adjustment or repair should be agreed separately. RTS must confirm supported functions, ranges, reporting and any required accreditation before equipment is booked in.
What to include in your enquiry
- Instrument type, manufacturer, model, serial number and asset identification.
- The functions to be checked, distinguishing AC, DC, measurement and source outputs.
- Working ranges and preferred test points, including frequency where relevant.
- Manufacturer specifications and any acceptance limits used by your quality system.
- Test leads, probes, adapters or accessories that form part of the measurement setup.
- Previous results, known problems and whether adjustment is requested or must be avoided.
Confirm before booking
- Confirm RTS can cover each requested function, range and any required measurement uncertainty.
- Agree calibration-only work or any separately authorised adjustment or repair.
- Confirm required accessories, handling arrangements and the documentation needed for your application.
Common questions
- Does a DC voltage check cover every multimeter function?
- No. Current, resistance, AC voltage and other functions have their own test requirements. List the functions you use and their working ranges so the scope does not unintentionally omit an important measurement.
- Does calibration automatically include adjustment?
- No. Calibration can document performance without changing the instrument. If adjustment is wanted, agree it in advance and ask how the readings before and after adjustment will be recorded. Repair availability must also be confirmed with RTS.
