Calibration Checkbox

This versatile budget Calibration CheckBox can be used to check all types of electrical test equipment.

How does it work?

Simply plug your meter (digital or analogue) into the Calibration CheckBox to test for continuity (0.5 - 10 ohms) and insulation (0.5 – 50 Mohms).

The requirements, as laid out in the NICEIC handbook, make it self-evident that electricians only need to do two tests on site (insulation and continuity) in order to meet Part P and 17th Edition Regulations. Earth Fault, Loop Impedance and RCD Tests are allowed to be done in an office using a known socket!
