Description LCD Display:-screen LCD with a full sight of 180 ,The blue backlight can be turned on/off manually. Two modes: normal display mode and dormant mode. No screws design:-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 batterys , discharge current, discharge power, discharge impedance, internal resistance, capacity, dump energy, energy consumption and running time, and display the measurement data through LCD screen. Normal working state: 0.03-1.2 W Sleeping state: 0.5mW-0.5W Working temperature-20C - +60C. Display interface is -screen LCD, it can display eight parameters at the same time. Power: Measuring range: 0-60000W, Starting measure power: 0.2W Impedance: Measuring range: 0-1000 : Measuring range: 0-200V. (when the test is Less than 8V, use the power supply mode) Current: Measuring range: 0-300A. The starting test current: 20mA Internal resistance:Measuring range: 0-999m Capacity: Measuring range: 0-1000AH Dump energy:Dump energy is display via the battery , totally 10 grids, grid 10% energy. Accumulate energy consumption:1 Measuring range: 0-9999kWh Note: 1Wh=0.001kWh=0.001 Kilowatt Running time:Measuring range: 0 - 999 hour (without load the time will not accumulate) colour:black Material:ABS+ electronic components size:89*50*44mm Package Contents: 1 * Battery Monitor Meter 1 * DC 300A Splitter Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
