- 【Multi-function 】The circuit tester offers full range of electric measurements:AC&DC Voltage/Resistance/Continuity/Frequency/Capacitance//Live Wire/Diode/Phase Sequence.
- 【Non Contact Voltage Tester】The electric detector enables you to detect voltage without any contact which largely avoids electrical shock.
- 【Beeper&Indicator Bar】Both are activated when voltage is detected.The frequency of warning tone and the color of indicator light varies depending on the voltage level
- 【Auto Mode】Operating with auto mode, the electrical checker automatically identifies what is being measured among Voltage, Resistance and Continuity, and shows the reading on display.
- 【Customer Service】36-month technical support is guaranteed. Please don’t hesitate to contact us if there are any questions with our ST100 smart voltage tester.
