6. Instruccions de funcionament

6.1 MESTEK AC50 Non-Contact Voltage Tester Pen

1. Encès: Press the power button to turn on the device. The default sensitivity is low (48V-1000V), indicated by "LO" on the screen.
2. Ajustar la sensibilitat: Short press the H/L button to switch to high sensitivity (12V-1000V), indicated by "HI" on the screen.
3. Voltage Detecció: Place the tip of the tester near the wire, outlet, or circuit you wish to test. If AC voltage is detected, the tip will flash, and the tester will emit an audible beep. The LCD will show a red bar for live wires and a green bar for null wires.
4. Llanterna: Press the flashlight button to activate the built-in flashlight for use in dimly lit areas.
5. Wire Breakpoint Detection: Move the NCVT along a wire. The alarm will stop at the breakpoint.

6.2 MESTEK ST06 GFCI Outlet Tester

1. Connectar: Insert the ST06 tester into a standard North American 3-wire 120V electrical outlet.
2. Read Indication: The clear LCD will display the wiring condition (e.g., "CORRECT," "OPEN GRD," "HOT/NEU REV"), voltage, and the time required to trip a GFCI device. The green and red LEDs will also provide visual indications.
3. Prova GFCI: Press the "TEST" button to simulate a ground fault. A working GFCI outlet should trip (turn off power) within the displayed time.
4. Restablir: After testing, press the "RESET" button on the GFCI outlet itself to restore power.
