Socket & See CB400 Professional Instrument Check Box

Socket & See CB400 Product Description:

The SOCKET & SEE CB200 provides a quick and simple method of checking the accuracy of electrical installation test instruments.

The Socket & See CB400 does not replace some calibration requirements but provides a ready check on instrument accuracy helping to minimise incorrect certification and costly revisits to confirm installation compliance. The Socket & See CB400 provides accuracy checks for test instruments used to measure:

• Continuity
• Insulation Resistance
• Earth Fault Loop Impedance
• Operation of Residual Current Devices.

Socket & See CB400 Features:

• Non-trip RCD testing method
• Continually validate your instruments through regular self-calibration checks
• Reduces expensive calibration costs
• Null facility to remove lead resistance
• Six Insulation check levels
• Five Continuity check levels
• Three Loop check levels
• Five checks covering 30mA and 100mA RCD’s
• Checks RCD over current test
• Tough drop-proof watertight case
