LCD Display:Large-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 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-20'C - +60'C. Display interface is large-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 Voltage: Measuring range: 0-200V. (when the test voltage is Less than 8V, please 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 symbol, totally 10 grids, every grid present 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 picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
