The Martindale ET4500 Installation Tester carries out all the tests needed to verify the safety of electrical installations in domestic, commercial and industrial wiring installations in accordance with the very latest amendment 3 to the BS7671 17th Edition Wiring Regulations which is effective from January 2015. The ET4500 simplifies 17th edition testing by having the latest amendment 3 fuse tables for Zs values built-in together with red and green LED indicators for instant pass/fail results. Fast, reliable high current and non-trip loop testing comes as standard together with a high level of input protection and a CAT IV safety rating . The ET4500 includes phase sequence indication and TRMS voltage measurement to cover every job and ensure voltage levels are really within the new Cmin limits defined in amendment 3. The ET4500 can be used to carry out 3 wire earth testing and has on board memory to store and download all installation test results for documentation. It is also supplied with low loss AA rechargeable batteries which can be easily recharged in the tester with the mains adaptor or optional in-car charger. FEATURES Insulation Resistance at 50/100/250/500/1000V. Continuity Testing at 200mA and 8.5mA. Loop Resistance and PFC dual display. Auto RCD and Ramp Test. TRMS Voltage, Frequency and Phase Sequence. 300V CAT IV, 600V CAT III safety rating. Memory and download for documenting results.
