This testing station is equipped with the EXTECH 7120 AC withstand voltage tester for electrical insulation safety verification of finished products. First, implement site hazard isolation: post bilingual high-voltage danger labels on the tester and mark the dedicated testing area with a station sign to remind operators of live high-voltage risks. Before testing, operators must check power wiring integrity of the H.V. and RETURN terminals, confirm red high-voltage probes have no insulation damage, and cut off idle power sockets to avoid accidental contact.

Standardize operation steps: Switch on the device, use SET/arrow buttons to set test voltage and hold time matching product safety standards. Press the green TEST button only after placing the tested product and keeping hands away from test probes; stop testing immediately via the red RESET button once leakage over-limit alarm triggers. After each test, wait for full voltage discharge before touching samples.

For risk control, prohibit touching output terminals during operation, and attach a warning sticker listing four high-voltage forbidden rules on the tester front panel. Arrange daily equipment calibration records to guarantee test data validity. This solution integrates equipment management, operating specifications and safety warning rules, effectively reducing electric shock accidents and ensuring all products pass standardized withstand voltage compliance inspection.
