HT97 Socket Tester Pro Voltage Test LCD Digital Outlet Socket Detect US/UK/EU Plug Ground Zero Line Plug Polarity Phase Check

Feature: ①SIMPLE OPERATION: Simply insert the tester into an already powered three-pin socket. The socket wiring condition and AC voltage can be easily determined based on the information displayed on the instrument screen. ②SOCKET WIRING SEQUENCE TEST:Insert the tester into a standard three-pin power socket. If a wiring sequence error is detected, the orange backlight will illuminate to indicate a wiring error. Refer to the display to identify the specific type of wiring error. ③DATA RETENTION:After inserting into the socket, the data automatically locks after three seconds. Once locked, press the unlock button to release the data. ④LEAKAGE SWITCH DETECTION:Insert the tester into a three-pin socket, ensuring that the display indicates correct wiring. Press and hold the RCD button for more than 2 seconds. In this case, a functioning residual current device (RCD) should trip, displaying the ripping time. The button indicator will flash, indicating the completion of the tripping process. If it does not trip, it suggests a malfunction in the residual current device. ⑤AUTOMATIC SHUTDOWN:If there is no operation within 5 minutes of powering on, the instrument will automatically shut down. ⑥PRODUCT SAFETY AND RELIABILITY:Rated safety level CAT II 300V ensures safe usage and quality assurance. ⑦PORTABLE AND CОMPАСТ:Portable for easy carrying, convenient operation. ⑧HIGH-DEFINITION BACKLIGHT LARGE SCREEN:The high-definition backlight display screen ensures clear visibility of measurement content even in dim environments, providing a clear and easily understandable view of the test results. ⑨WIDELY APPLICABLE SCENARIOS:Can be used to inspect the safety of socket wiring in homes, offices, shopping malls, and places.
