Product Details
The Martindale EZ2500, with patented T-Safe
TM technology, is an excellent earth loop impedance with true plug and go technology, that fits in the palm of your hand. Simply plug it in and it will automatically run a non-trip P-E and P-N loop impedance test, displaying the test results along with PFC and PSC readings. In addition it will check the socket wiring status and the voltage.
Test readings scroll through in sequence on the clear, backlit, 32 character display to show socket problems or high/ low voltage conditions. The loop impedance test results, PFC and PSC calculations are then displayed. Complies with BS EN 61010, BS EN 61557 & BS 7671 (17th Edition). Designed for use on 240V systems with 30mA or greater RCDs.
The Martindale EZ2500 is supplied with a 3 way lead set, with 2 fused probes and croc clips, and 1 unfused croc clip, mains test lead, instruction manual and soft carry case.
