  • Mains Tester Screwdriver is fitted with a neon indicator in the clear plastic handle which illuminates when the point of the tester is touched on a live voltage source of between 120-250 volts and an earthing contact is made with the metal stud on the top of the handle.
  • Main tester is fully insulated and is supplied complete with full operating instructions and will perform the following tests: continuity, bulbs, fuses, short circuits, cable tracking, mains sockets and microwave oven leakage.
  • Main tester will test electricity up to 250 volts. Hold the Main tester by the insulated handle, do not touch any part of the exposed metal blade. Always test the Main tester before you start by contact with a known live power source. You do not need to touch the touch pad at the top of the Main tester (although it is perfectly safe to do so).
  • The red LED will glow brightly when the Main tester metal blade is in contact with a live circuit, indicating that it is functioning correctly.
  • Hold the index finger against the cap end of the electric pen, thumb and middle finger, and gently pinch the electric pen with your ring finger to keep it stable, and then insert the metal nib into the socket panel hole on the wall or the external power strip socket hole.

  • SAFETY FIRST: It will send out multiple alarms through sound and light. When the voltage is detected, the tip will send out red light and beep. When the higher the sensed voltage is, or the closer it is to the voltage source, it beeps at a higher frequency. At the same time, the screen will be red or green, red means high voltage and live wire are detected, green means low voltage and null wire are detected.
  • NON-CONTACT: With NCV inductive probe for AC voltage; Just place the tip near a terminal strip, outlet, or supply cord. When the tip glows red and the pen beeps, you know there's voltage present. The live wire detector can automatically detect the live or neutral wire. Ideal for breakpoint Test. Handy circuit tester for electricians, homeowners.
  • DUAL RANGE: Detects standard and low voltage (12-1000V AC / 48-1000V AC) for more sensitive and flexible measurements. Press the S button to adjust sensitivity and adapt low range for doorbells, thermostats, irrigation wiring etc.; The NCV sensor automatically recognizes the voltage and displays it on the bar graph.
  • SECURITY LEVEL: IEC rated CAT III 1000V CAT IV 600V, Meets CE requirements; The electrical tester is safely double insulated. High Voltage Alert to warn you of voltage above 90V, the screen turn red and the safety symbol on the screen shines.
