the voltmeter will be damaged.
 
Product Features
  

         
Three-wire connection enable the voltage test rang from 0.00 to 30V;Two-wire meters cannot measure the voltage that is below 3V.
         
Accuracy:Accuracy can be adjusted automatically, less than 10V can be accurate to 0.01V, greater than 10V can be accurate to 0.1V.
         
Display: Three 0.36" digital LED Tube;0.36" visible LED display, easy to read even in dim light.
         
Feature:With reverse polarity protection, the meter will not burn out when the polarity is reversed, but it is not displayed on the screen.Only three wires,easy to connect.
