Martindale TEK100 Non-Contact Voltage Indicator
Simply hold the Martindale TEK100 Non-Contact Voltage Indicator near a voltage source from 100-600V AC and it’ll let you know if voltage is present.
If voltage is detected, the TEK100 will use a combination of an audible tone and a red visual indicator to alert the user. A built-in self testing function allows the meter to remain accurate throughout its lifetime and will check the tip of the tester at 50Hz plus the condition of the battery and LED indicator.
The self-testing function eliminates the need for a separate proving unit.
This is suitable for detecting 100V to 600V AC without requiring physical contact with the conductor. The presence of any voltage between 100V and 600V AC will generate an audible tone, together with a red visual indication.
The integral self test activates the sensor in the tip of the tester at 50Hz as well as checking the battery and LED. The entire circuit, not just the indicator LED, is therefore tested.
This proves that the unit is fully functional and avoids the need for a separate proving unit.
The only non-contact detectors with a built-in proving device that really proves the entire circuit.
