Calibration Checkbox for checking Instrument calibration

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). You can test for RCD and earth loop impedance back in your office on a known socket – leaving the Calibration Checkbox as an essential on site tool for all electricians.

The requirements as laid out in the NICEIC handbook makes it self-evident that electricians need only do two tests on site (insulation and continuity) in order to meet the Part P regulations; the other earth fault loop impedance and RCD tests were allowed to be done in their office using a known socket!

This means that the calibration checkbox complies with the requirements to regularly check the accuracy of your instruments at regular intervals.

The Calibration Checkbox has been made with safety in mind and carries CE marking according to The Safety Requirements for Electrical Equipment for Measurement, Control and Laboratory Use EN 61010-1:2001 and Low Voltage Directive 73/23/EEC and amendment 93/68/EEC. Can be used for all types of electricians test equipment.

Unlike other checkboxes this unit is manufactured with high spec resistors that will not be damaged by a 1000v insulation test.
