Multifunctional Tester: including the measuring functions of AC/DC voltage, resistance, capacitance, temperature, diode, on/off, phase sequence, zero fire wire, etc. Intelligent Voice Broadcast: the data measured by the meter will be broadcasted by voice. NCV Power Sensing: it will flash red light and sound an alarm when a nearby AC voltage is detected. Phase Sequence Detection: after the pen tip is close to the phase line and the test ABC is completed, the display screen will display the test result on the screen. Flashlight Function: let you no longer be afraid of invisible measurement position in dark environment, lighting up the working area to assist night work. Detachable Nickel-plated Tip: unscrew the detachable metal nib with pliers, replace with different measuring nibs. LCD VA Color Reverse Display: 6000 counts max. display, with data hold function, you can read the measured value clearly in the dark environment. Power Supply: runs on a single AAA battery, low power consumption and easy to replace the battery. Wide Applications: pen multimeter can measure a variety of electronic components to meet your needs for versatility, very perfect for home, office, laboratory, factory, and other application.
