["This product is a universal instrument, the color LCD screen, with low power consumption,\nlong for time switch, can display the battery voltage, can be used in a variety of lighting conditions. \n\nFeatures:\n1. The patented product, neutral packaging production, with simple dustproof waterproof\nsurface, with full for protection cover.\n2.The color liquid crystal material, light clear display, display the soft night.\n3.To customize the type of battery, suitable for lead-acid, lithium-ion batteries, lithium iron\nphosphate, metal hydride battery.\n4.To display the percentage of remaining battery power,voltage, temperature value.\n5.The 10~100V wide input voltage,reverse for protection.\n6.The product can go to sleep after 10 seconds.\n7.The low power red mark flashes to remind.\n8.The installation is simple, with a buckle, without screws.\n9.The open programming mode\n\nParameter:\nProduct size:61.5mm*33.5mm*13.5mm\nInstallation size:58.5mm*28.5mm\nDisplay size:36mm*19.5mm\nWorking voltage:10V-100V\nPower waste:5-6mA (LED ON)\nVoltage accuracy:±0.1(Typical),±0.5(Max)\nSleep power:6-12uA (20V)\nWorking temperature:-10~55℃\n\nInstruction:\n1. PH2.0 terminal products supporting the use of wire, connected to the circuit board face should plug back.\n2. External NTC temperature sensor, please put the sensor to measure the temperature of the parts, do not\nsqueeze the sensor( selective assembly).\n3. Red line to the positive terminal, black line to the negative terminal.\n4. After the instrument is powered on , which shows the percentage of the battery power, the voltage value,\nand the symbols of the analog battery.\n5. Press the button to turn off the instrument. In close mode, you can wake up the instrument by pressing\nany button.\n6. Click the button , you can switch the voltage value and temperature value display.\n7. The battery symbols on the display interface, from the right to the left, are 7 display boxes representing the\npool power from low to high.\n8. The voltage on the display interface is measured in real for time, and the voltage value is displayed on\n10-100V.\n9. The percentage on the display interface is the percentage of the remaining battery power\n10. When the battery is connected to the charger or the discharge of the high current load, the display\nparameters will fluctuate\n11. The red for lightning flashes the alarm when the battery is low\n12. If the battery specification is special, you can enter the set mode 3-- and reset the upper and lower limits of\nthe measured battery voltage.\n\nNotice:\nThe default setting is suitable for use in 12V lead acid batteries.\nIf you need to set up other types of batteries, or go into settings mode and delay for time switch settings, please contact us, we will send electronic English instructions to you.\n\nNote:\nPlease allow 1-3mm error due to manual measurement. pls make sure you do not mind before you bid.\nDue to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!\n\nPackage include:\n1pcs Battery Capacity Indicator Voltage Monitor"]
