Multifunctional: This kind of multimeter is suitable for measuring the voltage, current, resistance, temperature, continuity testing and diode, providing you with precise data. Easy reading: You can read the data clearly because this is designed with a large screen, and it works with 9999 counts, convenient for you to know the real-time condition. Backlight: This kind of digital display is a good supply for you to read data in dark conditions, you can send it to the electrician as a good present. Electric: Powered by 2x 1.5 AA batteries(not included), you do not need to charge it, saving time and strength for you, you can order according to your likes. Circuit protection: This kind of testing meter is designed with overload protection when metering, and it will show you the low battery electricity and voltage. It is safe to use because it adopts dual insulated protections, and you can place it on the desktop, providing you with a large viewing angle. Specification: Colour: show as pictures.
