1. The power supply voltage used in this voltmeter should not be higher than 18V. Please pay enough attention to the table to avoid permanent damage to the voltmeter due to motor spark, power supply ripple or other excessive abrupt voltage.
2. Since this voltmeter uses LED display, it requires a certain working current, so it cannot be used for high internal resistance voltage measurement, such as weak signal voltage and button battery.
3. Pay attention to the wiring method. The red line is connected to the positive line, and the black line is connected to the negative line
