Feature:<br />1. Small in size， show two digitals after decimal point. Need external power supply. Power supply has reverse connecting protection.<br />2. High light LED digital tube， perfecto displaying effect.<br />Product: DC Ammeter<br />Display color: Yellow<br />Appearance: nude package<br />Dimensions: approximately 35 x 18 x 9 mm<br />Lead length: about 19cm<br />Measuring range: DC 0-10A<br />Power supply range: 4-30V <br />Leading wire: thick white line (current input)<br />thick black line (current output)<br />red line (power supply positive electrode)<br />black line (power supply negative electrode)<br />Note:<br />1. In order to give power to ammeter in measured circuit， this product's power supply and input are disigned in same ground line. This means that the black line is ground line， another thick line connects amplifying circuit and input of ammeter. <br />2. Sample line (thick line) should connect negative electrode， or it will burn ammeter immediately. <br />3. Ammeter's two thick lines should connect two negative electrodes.<br />4. Please do not use bad power adapter. The leading line you use to connect shunt and ammeter cannot be too long. You can use shielded line if long line is needed.<br />1 x Ammeter<br /><img src="http://img6.eachbuyer.com/x7/p30/v144_4.jpg" />                                                        <img src="http://img6.eachbuyer.com/x7/p30/v144_5.jpg" />                                                        <img src="http://img6.eachbuyer.com/x7/p30/v144_6.jpg" />
