1. High precision, high reliability, suitable for high-end applications
2. Small size, can display voltage and current at the same time
3. Reverse connection protection, reverse connection will not burn, using common ground design
4. Anti-collision design with shell, more durable
5. Adopt industry standard size, more convenient to install
6. Ambient temperature: -15 to 70 degrees Celsius
7. Measuring voltage: DC0-100V, 0-10A
8. Working voltage: DC4.5-30V
9. Working air pressure: 80-106kpa
10. Working current: less than or equal to 20 mA
11. Precautions: Because the meter head adopts a common ground design, that is, the ground wire of the measuring end is the same as the ground wire of the electrical end, so it can only be connected between the negative pole of the device under test and the negative pole of the power supply.
12. Dimensions: 48 x 29 x 21cm
