Calibration of Test Equipment

https://www.ptscalibrations.co.uk/ Calibration questions. Electronic measuring instruments have to be calibrated annually or as recommended by the manufacturer to meet with current guidelines.

This does not replace the requirement for an annual calibration. The calibration checkbox will also require an annual calibration.
