Multimeter &Voltage tester &Phase sequence tester 3 in 1 You don't need to buy a lot of measuring tools, only one ST120 multimeter is enough, and the range of ST120 is enough to use, and its accuracy is relatively high. Core Function The functions of ST120 are more comprehensive, ST120 can measure DC/AC voltage,Resistance, Capacitance, Frequency, Phase Sequence, Live Wire, Diode, Continue. High Voltage Alarm You can use the red probe contact to the conductor to test wires. When the weak electric field signal is detected it will display"---L"the buzzer will sound slowly and the green light on. When the strong electric field signal is detectedit will display "---H" the buzzer will sound quickly and the red light on. Non-contact Phase Sequence Dection P---L showed on the screen indicates aleft-handed phase sequence. P---R showed on the screen indicates aright-handed phase sequence. Color Screen You can see more clearly on this screen Flashlight Lighting You can use it conveniently even at night Smart Mode Automatically identify the measurement signal, Automatically select the range In this mode, the meter can automatically measure DC/AC voltage, Resistance, Continuity. Easy to use: 1)Pre the power key to power on, display"Auto" and enter the smart measurement mode. 2) Insert the black probe into the"COM" jack. 3) Contact the probe with both ends of the measured subject or resistance paralleland the meter will automatically recognize the measured signal. 4) Read the results from the display. Easy To Carry In order to make it more convenient for you to use or carry, we have designed the appropriate size Function Keys Input Terminal Signal Intensity Indicatorl LCD Display Function Kay Input COM Terminal Product Show What Will You Receive: 1ST120 Pen Multimeter 1Tester line 1User Manual 1Box
