LCD Display:-screen LCD with a full sight of 180 view,The blue backlight can be turned on/off manually.Two modes: normal display mode and dormant mode.No screws design:Push-on terminal,no need to connect with a screw.Wildly application:DC multifunction battery meter wildly applied to solar system/industrial assembly line/Automobile/RV etc.The PZEM-015 DC multifunction battery is mainly used to test all kinds of battery's voltage, discharge current, discharge , discharge impedance, internal , capacity, dump energy, energy consumption and running time, and display the measurement data through LCD screen.Normal working state: 003-12 WSleeping state: 05mW-05WWorking temperature-20'C - +60'C.Display interface is -screen LCD, it can display eight parameters at the same time.: Measuring range: 0-60000W, Starting measure : 02WImpedance: Measuring range: 0-1000Voltage: Measuring range: 0-200V. (when the test voltage is Less than 8V, please use the supply mode)Current: Measuring range: 0-300A. The starting test current: 20mAInternal :Measuring range: 0-999mCapacity: Measuring range: 0-1000AHDump energy:Dump energy is display via the battery , totally 10 grids, every grid present 10% energy.Accumulate energy consumption:1 Measuring range: 0-9999kWh Note: 1Wh=0001kWh=0001 KilowattRunning time:Measuring range: 0 - 999 hour (without load the time will not accumulate)colour:blackMaterial:ABS+ electronic componentssize:89*50*44mmPackage Contents:1 * Battery Monitor Meter1 * DC 300A SplitterOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
