Feature:
1. Dual Display: Display Voltage and current at the same time; Power supply: DC3.5‑30V; Voltage test range: 0~300V; Current test range: ± 0‑9.99A.
2. Good Consistency: With exquisite SMT process, common ground design, the measurement end and the power supply end ground wire are connected (except for the isolation table).
3. Calibration: Equipped with voltage calibration potentiometer, current calibration potentiometer, if there is an error, you can calibrate it yourself.
4. High Performance: The voltmeter adopts decimal point automatic shift design, which has strong anti interference ability and fast display refresh speed.
5. Practical in Use: Easy to connect, with a wide power supply range of DC3.5‑30V (except for isolation meters), and has power supply with reverse polarity protection.
