Electrical outlet tester, HT97D digital outlet tester, voltage tester, plug and socket detector, smart leakage tester, multi-function phase tester

SIMPLE: Simply insert the tester into a live three-prong outlet. The outlet wiring status and AC voltage can be easily determined from the information displayed on the instrument's screen.

OUTLET WIRING SEQUENCE TEST: Insert the tester into a standard three-prong power outlet. If a wiring sequence error is detected, the orange backlight will illuminate to indicate a wiring error. Refer to the screen to identify the specific type of wiring error.

DATA HOLD: After insertion into the outlet, data is automatically locked after three seconds. Once locked, press the unlock button to release the data.

LEAKAGE SWITCH DETECTION: Insert the tester into a three-prong outlet, ensuring the screen indicates correct wiring.

Press and hold the RCD button for more than 2 seconds. A functioning residual current device (RCD) should trip, displaying the trip time. The button indicator will flash, indicating the end of the tripping process. If it does not trip, this suggests a residual current device malfunction. AUTO SHUTOFF: If no power is applied within 5 minutes, the instrument will automatically shut down. PRODUCT SAFETY AND RELIABILITY: The CAT II 300V safety rating ensures safe operation and quality assurance. LARGE, HIGH-DEFINITION BACKLIT DISPLAY: The high-definition backlit display ensures clear visibility of measurement content even in dark environments, providing a clear and easily understandable view of test results. WIDELY APPLICABLE SCENARIOS: Can be used to inspect the safety of socket wiring in homes, offices, shopping malls, and other locations.
