"Feature description
1. The wiring of this voltmeter is simple. Two wires are used conventionally, red is connected to positive, black is connected to negative, there is reverse connection protection inside, and the connection is not burned.
2. There is no need for external working power supply, it can work directly with the measurement voltage, and the measurement voltage range is 2.4-30V on the second wire.
3. Wide voltage operation, the red low measurement voltage is 2.4V, and the large safe pressure can reach 40V. If it exceeds 40V, it may be damaged.
4. When measuring voltages below 10V, two digits are displayed after the decimal point; when measuring voltages above 10V, one digit is displayed after the decimal point.
5. For other needs or test scope [three-wire 0-100V, please take links to other products].
Parameters Table:
Measuring range: two-wire DC2.4～30V
Power supply range: no separate power supply is required. The measured voltage <40V higher than 40V may be damaged
Test accuracy: Accuracy can be calibrated, with adjustable voltage resistance
Input impedance: >50KΩ
Working current: <30mA
Refresh speed: about 100mS once
Display specifications: three 0.28LED digital tubes (5 colors of red, blue, green, yellow and white are available)
Lead length: default 15cm
Dimensions: 30 x 11.5 x 9 mm
Hole size: Hole distance: 26mm Aperture: 2.2mm
Working temperature: -10 ~ +65℃
Working humidity: 10 ~ 80%
Working air pressure: 80 ~ 106kPa
