Socket & See CB400 Non-Trip Installation Calibration Checkbox

The Socket & See CB400 Non-Trip Installation Calibration Checkbox is a modern leap in calibration technology. It goes far beyond the basic features of standard calibration cards and checkboxes. This advanced tool helps ensure your installation testing equipment matches current wiring regulations. It also guarantees accurate results in your certification work. With the CB400, professionals can be confident their testing instruments are working properly. This supports the accuracy of electrical safety checks and compliance assessments.

Designed for compatibility, the CB400 seamlessly integrates with all the leading brands of Loop, Insulation/Continuity, and RCD Testers, including both multifunction and single-operation devices. It’s an indispensable asset for ensuring compliance with BS EN 61557 Test Instrument Requirements. The device is remarkably user-friendly: simply connect it to a mains supply, attach your testing equipment, and proceed to document the results. This process not only affirms the precision of your tools but also significantly reduces the need for costly calibrations.

The CB400 doesn’t just offer technical quality; it also comes encased in a rugged, shockproof, and waterproof case, ready to handle the rigours of daily use in challenging environments. The addition of a no-trip RCD testing method, alongside various levels of protection, connection, and loop checks, ensures thorough checking of your testing instruments. Furthermore, the CB400 features a null facility to cancel lead resistance, improving the accuracy of your measurements.
