About this item

• Multi-parameter Measurement ST100 Voltage test pen offers full range of electric measurements:ACDC Voltage/Resistance/Continuity/Frequency/CapacitanceLive Wire/Diode/Phase Sequence.
• Non Contact Voltage TesterVoltage is detectable with NCV Tester. Measuring voltage without touching wires largely avoids electric shock.
• BeeperIndicator BarBoth are activated when voltage is detected.The frequency of warning tone and the color of indicator light varies depending on the voltage level
• Auto ModeOperating with auto mode, the electrical checker automatically identifies what is being measured among Voltage, Resistance and Continuity, and shows the reading on display.
