Electrical calibration FAQs
What is electrical calibration?
Electrical calibration is the process of testing and verifying the accuracy of an item of electrical test equipment. Electrical calibration involves the documented comparison of the equipment against a traceable reference device.
Calibrating electrical equipment at regular intervals is a key part of quality management when it comes to the delivery of products and services, and in many cases is required for legislative and regulatory compliance.
What causes measurement drift in electrical testing equipment?
Over time, due to regular use or periods in storage, measurement drift (accuracy reducing over time) can occur in electrical devices. The way equipment is used and stored can contribute to the speed and scale of this drift.
Environmental factors (e.g. dryness or humidity), out of range usage or careless handling can all accelerate measurement drift.
How often does electrical equipment need calibrating?
The optimal interval for electrical calibration will differ based on a number of factors – most notably how at-risk devices are in terms of measurement shift (considering the factors covered above). Other factors to consider are the type of equipment and frequency and applications of use. Carrying out electrical equipment calibration every 6-12 months is a good rule of thumb, but companies should consult manufacturer instructions for more detailed guidance.
What is UKAS calibration for electrical equipment?
UKAS Calibration can only be carried out by a calibration house and using equipment that has been independently audited and accredited by UKAS to carry out the work. UKAS is the only body recognised by the government for assessing the quality of calibration. D+M Systems & Test is fully authorised to perform UKAS standard calibration.
