0.28 inch DC 32V Dual LED Digital Voltmeter Ammeter Voltage AMP Power Two-wire
- 1. The wiring of this voltmeter is simple, two wires are conventionally used, the red is connected to the positive and the black is connected to the negative.
- 2. No external power supply is required for normal operation, and it can work directly with the measuring voltage. The measuring voltage range is 2.5-31.5V in two wires.
- 3. Wide voltage operation, the red minimum measurement voltage is 2.4V, and the maximum safe bearing voltage can reach 40V. If it exceeds 40V, it may be damaged.
- Measuring range: two-wire DC2.4-32V
- Power supply range: No separate power supply is required. The measured voltage Test accuracy: accuracy can be calibrated, with adjustable voltage resistance
