From the shop's description

0-100Vdc Three Wire Digital Voltmeter 0.28 inch This voltmeter can be used to measure the storage battery’s?voltage in motorcycles and cars and also can grasp the storage batterys status. It also can be used to measure other voltage. 100V is the voltmeters maximum operating limited voltage, please leave enough margin when working, to avoid voltmeters permanent damage because of an electrical spark, power supply ripple, or other too high abrupt change of voltage. Very bight and decent LED Display is ready to measure the dc voltages in the range of 0V to 100V. Red Wire: ?Positive of the Power supply Black Wire: ?Negative of the Power supply and also used as the negative of the measurement voltage source White: Positive of the measurement voltage source Specifications: Accuracy 0.1 V Color Red, Yellow, Blue Wires 3 Display ON Voltage (V) 3 Operating Voltage (VDC) 0 ~ 100 Current Consumption (mA) 10 Refresh Speed (ms) 200 (one time) Minimum Input (V) 3 Highest Input (V) 30 Operating Temperature (C) -10 to 60 Holes for Mounting 0.3 cm Height (cm) 1.3?cm Length (cm) 0.72?cm Width (cm) 3?cm Weight (gm) 3 gm Package Includes: 1x 0-100Vdc Three Wire Digital Voltmeter Related Products: Panel Meters
