Calibration Check Box
Calibration Check Boxes
For peace of mind you should check the calibration of your 18th edition testers between formal calibrations. Independent electrical contractor’s voluntary bodies such as NICEIC and NAPIT recommend interim calibrations to check the on-going accuracy of all test instruments known as periodic checks.
A calibration check box will allow you to check settings such as: Insulation testing, resistance and continuity, voltage, impedance all pieces of test equipment, as standard, conform to manufacturers specifications. These results generally become less accurate over time due to the effects of drift. Drift can cause a tester to start generating erroneous readings (extremely dangerous if working with electrical installations), leading to you perhaps being convinced that an installation is safe when it really isn't. Drift can be caused by all kinds of factors. Whether it's a sudden surge in electricity passing through the tester, a bump loosening vital components or just the effects of age, dirt and grime, drift can be caused by a wide variety of different things.
This is exactly why we carry out checking, in order to ensure that test equipment is as accurate as it can possibly be. Regular in-service checking of test equipment is more likely to keep you within the boundaries of the compliance expected and regulated by the test inspection authorities. It is also a requirement that test equipment is still calibrated by a qualified calibration laboratory according to manufacturer’s recommendations. The level of accuracy offered by calibration laboratories is generally much higher than using a calibration check box.
It is also worth noting that using a calibration check box will not generate a fully traceable certificate that may be required by companies wanting a contractor to carry out work.
Calibration check boxes are just that check boxes. This means that calibration check boxes are ideal for checking overall accuracy, but the full formal calibration procedure must always be completed in accordance with manufacturer’s recommendation and this will then give you a calibration traceable to National/ Standards / UKAS Test Equipment
We offer a range of calibration check boxes at Glanford Electronics.
