Features 1. AC voltage measurement: Set to the corresponding voltage range and use a probe to measure the commonly used AC voltage in the household. It is easy to use and fast to measure. 2. The back contraction support bracket provides more accurate measurement, and there is an extended support bracket on the back that effectively supports the multimeter. When measuring, it can be tilted and placed on the table for easy standing operation. 3. Measure the hFE transistor by setting the multimeter to the hFE position to determine whether the transistor is NPN or PNP, and insert it into the corresponding socket of the transistor. 4. NCV non-contact, non-contact electrical measurement, to prevent electric shock hazards. When AC voltage is detected, there will be an alarm sound prompt, and the closer to the power supply, the more urgent the alarm will be. 5. High definition backlit screen: Long press the backlit button to turn on the backlight, and even in dark environments, the screen values can be seen clearly. Pressing the H button alone can maintain the current values and easily read them.
