BSIDE S8 Smart Multimeter Digital AC Voltage Detector Electrical Leakage Tester 3 in 1 Large Colour Display Electric Circuit Pen Rechargeable Capacitance VFD Ohm Hz Live Wire Continuity

[Easy to Use] : This smart multimeter pen automatically measures AC DC voltage, resistance, continuity when switching on, without adjusting the range or switching functions. Manual mode is also available. It can also test capacitance, diode, frequency, duty cycle etc. [Rechargeable Voltage Detector] : Powered by a built-in rechargeable battery, this electric tester pen works right out of the box. Simply press the V-Alert button for non-contact voltage detection. Low and High sensitivity can be adjusted for different wiring scenarios(90V-1000V/12V-1000V), such as accurately locating firewire in a clump of wires, or finding live wires in wall. [Voltage Leakage Testing] : With this electricity tester pen, you can check whether there is any electricity leaking from the metal casing of household appliances. Long press the V-Alert button to enter this mode to measure 12V-300V AC voltage. [Variable Frequency Voltage Test]: With this electrician's pen, you can also measure the output voltage of inverters. It helps you to better estimate the voltage of pumps, lifts, air conditioners, compressors, etc. and to better plan operating speeds. [Super Large Colour LCD]: Despite being a pocket voltage tester pen, it features a remarkably large screen with large digits, three-line colour display and ID pointer design, giving you a more intuitive and better assessment of real-time conditions and risks when working around electricity.
