Calibration Checkbox By plugging in either digital or analogue meters the Calibration Checkbox can be used to test for continuity (0.5
- 10 ohms) & insulation (0.5 – 50 Mohms). The requirements as laid out in the NICEIC handbook makes it self-evident that electricians need only do two test equipment calibration checks onsite (insulation & continuity) in order to meet the Part P regulations; the other earth fault loop impedance & RCD tests are allowed to be done elsewhere 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 main benefits are; • 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.• Meets the Part P regulations in the most cost effective way on the market.• 12 month warranty.• Truly portable device always at hand that saves your valuable time & money.
