Parts List: 1 x Multimeter 1 x Test Lead 2 x AAA batteries 1 x Instruction Manual Highlight description: [Automatic Measurement] By default, it enters the intelligent (automatic) mode, and the digital multimeter automatically recognizes and measures AC and DC voltage, resistance, and continuity. It also tests capacitors, diodes, frequency and live. [Phase Sequence] has a unique phase sequence detection. When the "PA" mode is turned on, the operator can detect whether the phase sequence is clockwise or counterclockwise. [Easy to Use] Use the "Func" key to switch the measurement mode, and use the "H" key to hold the data. The backlit LCD screen ensures clear readings in dark or bright areas. The flashlight under the red probe helps you work well in dark or low light environments. [Compact and Portable] Compared with other traditional multimeters, this pen multimeter is smaller and more powerful, making it more suitable for carrying around. [Wide Applications] Set includes 1 multimeter, 1 test lead, 1 user manual, 2 AAA batteries, suitable for industrial electrical safety measurement, household electrical problems, vehicle and circuit testing.
