Description:<br />This module uses high quality LED digital tube manufacturing? ultra-high brightness? but also clearly shows that even in the sun. It uses imported MCU sampling and display voltage? and the software has a lot of data processing? the display precise and stable. This module is a full-chip technology? exquisite workmanship? while ultra-small. The module has reverse polarity protection? even if it does not reverse damage to the module.<br /><br />Main Features: <br />Refresh rate: About 200ms time<br />Measuring range: 0V-100V<br />Current: Less than 8mA<br />Display: Three 0.36 inch digital pipe<br />Power supply: 5V-30V<br />Input impedance: About 100K<br /><br />    Specifications<br />Weight and Size<br />	 Product Weight: 0.005 kg                                                  <br />                        Package Weight: 0.065 kg                                                  <br />                        Product Size(L x W x H): 3.5 x 1.4 x 0.8 cm / 1.4 x 0.6 x 0.3 inches                                                  <br />                        Package Size(L x W x H): 4.5 x 2.4 x 1.8 cm                                                	<br />Package Contents<br />	 Package Contents: 1 x Voltmeter                                                	<br /><br /><br /><br />                                                <br />
