DescriptionDescriptionIn addition to detecting 28 socket wiring fault conditions and checking mains voltage levels, the EZ165 verifies the earth wiring by carrying out a non-trip earth loop test and indicating its value in 6 discrete ranges from less than 1.7Ω to 500Ω.A low earth resistance is essential for safety disconnection devices to work properly and prevent electrocution when faults occur. In contrast basic socket testers only indicate the presence of an earth and will do so even when resistance values are dangerously high.Socket polarity and earth wiring faults are identified by a combination of red LEDs. The 3 LEDs correspond to neutral, earth and live connections to aid fast identification of the source of common faults. A look up chart on the tester provides further fault diagnosis.The EZ165 is an Advanced Socket Tester as defined by the Health & Safety Executive as it indicates earth loop impedance. Advanced Socket Testers offer a simple solution to verifying socket earthing and are commonly used by engineers and technicians prior to servicing and installing mains powered electrical and gas appliances.SpecificationsNominal operating voltage230V AC rmsOperating frequency50HzPower consumption<2.5WPowerfrom mains socket under testNon-trip earth loop impedance ranges0 – 1.7 – 5 – 10 – 100 – 200 – 500ΩEarth loop threshold accuracy± (10% 0.3Ω) *Voltage low indication<195V ± 5%Voltage high indication>270V ± 5�rth neutral voltage high indication>30V nominalOpen earth indication>500Ω ± 10%Dimensions 65 x 80 x 59mmWeight93 g approxTemperature (Operating & Storage)-10°C to 40°C, at max. 60% RHAltitudeup to 2000mWeight93 g approxPollution degree:2Weight93 g approxSafetyConforms to BS EN 61010-1, CAT II 300V, Class II, double insulationEMCConforms to BS EN 61326-1* Measurement accuracy can be affected by highly inductive or capacitive loads distributed on the supply.
