Mini DC Voltmeters:Total 6PCS, 3 colors combined(2PCS Red/Blue/Green);
0.36 inch LED Panel:Small in size and light in weight; wire is made of 28awg gauge; install the hole: 3mm approx
2 Connection Methods:3 wires are connected separately to measure voltage and power(Red yellow is both for pos, black is neg); 3 wires are used as 2 wires, connected to measure voltage(Red and Yellow can be paired for pos, black is neg)
Features:Reverse polarity protection, voltmeter won't burn out if reverse polarity is applied; high precision; low starting working voltage; When the voltage is lower than 3.0V, the brightness will be darkened, but it will not affect the correct measurement
Note:Max voltage with yellow and red connected is 40V.To measure greater than 40V (up to 100V) the yellow wire is connected to a separate voltage source that is 40V or less
