Kyoritsu Electric Meter Outlet Tester KEW4505

------------------------------------------------------------------------------------------------------------------ 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ------------------------------------------------------------------------------------------------------------------ In addition to TT grounding, TN grounding can also be measured when used with a dedicated injector (sold separately). Easy operation, just plug it into an outlet and press the measurement button Possible to detect incorrect wiring between N-E (neutral and ground) with live wires Notification of normal/incorrect wiring with LED (green/red) lamp and buzzer Functionality is further improved when used in conjunction with a dedicated injector (sold separately): ① Can measure even with TN grounding ② Can measure up to earth voltage of approximately 20V ③ Can measure even with low grounding resistance ④ Will not trip a 15 mA earth leakage breaker (test current 1 μA or less) )
