Solar and cable location calibration

Seaward solar testers, solar power meters, CATs and gennys.

Solar PV testers and cable avoidance tools calibrated for installers and utility contractors.

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

Instruments we calibrate

  • Seaward PV100 or PV150
  • Seaward Survey 100R or 200R
  • Seaward solar kit, 2 items
  • Seaward solar kit, 3 items
  • Solar power meter
  • Cable avoidance tool (CAT)
  • CAT, downloadable
  • Genny

Why solar testers and cable locators need calibrating

Solar PV installers use testers such as the Seaward PV150 to commission and inspect PV systems, and the test results go on the documentation handed to the customer. If the tester is out of calibration, those results can't be relied on.

Cable avoidance tools (CATs) and signal generators (gennys) protect people digging near buried services. A CAT that has lost sensitivity can fail to detect a live cable, so its accuracy is a safety issue as well as a quality one.

How often should they be calibrated?

Manufacturers generally recommend annual calibration for solar PV testers, solar power meters, CATs and gennys. Many CATs have a built-in self-test, which is useful day to day but is not a substitute for periodic calibration.

What you get back

  • A calibration certificate with the make, model and serial number
  • Results for the functions checked, compared with 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. UKAS-accredited calibration can be arranged on request through our UKAS-accredited partner laboratory.

Common questions

Can you calibrate a Seaward solar kit together?

Yes. We calibrate Seaward PV testers and Survey irradiance meters individually or as two- or three-item kits.

Do you calibrate the CAT and genny as a pair?

Yes. Send them together and we calibrate both.

How do I get them to you?

Drop them at a Calibration Point partner branch and we'll collect from there, usually returning them within 3 to 5 working days.
