Electrical test equipment calibration

MFTs, PAT, insulation, loop, RCD, clamp meters and voltage testers.

The testers electricians rely on every day, calibrated against reference standards and returned with a certificate you can show any inspector.

All calibration is traceable to national standards and carried out under our ISO 9001 quality management system.

Why electrical test equipment needs calibrating

Every Electrical Installation Condition Report, Electrical Installation Certificate and PAT record you sign depends on the instrument you used. Insulation resistance, earth loop impedance, continuity and RCD trip times all rely on the tester reading accurately. If a multifunction tester or PAT tester has drifted, an installation or appliance can pass when it should have failed.

Scheme assessors from bodies such as NICEIC and NAPIT routinely ask to see in-date calibration certificates for the instruments you test with, so an out-of-date certificate can cause problems at assessment.

How often should an MFT or PAT tester be calibrated?

Most manufacturers recommend calibration every 12 months, and that is what assessors usually expect. Between calibrations, use a calibration check box to confirm your tester is still reading consistently, and keep a record of the checks. If a tester is dropped, damaged or repaired, have it calibrated again before you rely on it.

What you get back

  • A calibration certificate showing the make, model and serial number
  • Test results for each function against reference values
  • A statement of traceability to national standards
  • The calibration date and recommended due date

All work is carried out under our ISO 9001 quality management system. If a client or contract needs UKAS-accredited calibration, we can arrange it on request through our UKAS-accredited partner laboratory.

Common questions

Can I drop my tester off at my electrical wholesaler?

Yes. Hand it in at any Calibration Point partner branch and we collect it from there. Find a partner branch near you.

How long will I be without my tester?

Most instruments are back at the branch within 3 to 5 working days.

What happens if my tester fails calibration?

We contact you with a repair quote before doing any work. Nothing is repaired without your go-ahead.
