Voltmeter Features
1. Simple wiring: Red wire connects to positive, black wire connects to negative. The device is protected against reverse connections.
2. No external power supply is needed; the voltmeter operates directly from the measuring voltage (2.50-30V).
3. Supports wide voltage operation ranging from a low 2.50V up to a safe maximum of 40V. Voltages above 40V could cause damage.
4. Displays voltage readings with two decimal points for values below 10V, and one decimal point for values above 10V.
