["Description:\r\nThe TK15 is a new type of the high precision current collection capacity indicating parameter instrument, which is for lithium battery,lithium iron phosphate batteries,lead-acid batteries and nikel-metal hydride batteries,hereinafter referred to as coulometer. It can collect the working state of the battery at anytime. It has various fatures,such as a wide range of operating voltage, low power, high accuracy in indicating. It can set the payload capacity and other parameters of batteries arbitrarily, and with automatic memory function when power down.\r\n \r\nSpecifications:\r\nType: Battery tester\r\nModel: TK15\r\nOperating voltage range: DC8-80V\r\nCurrent: 50A\r\nOverall Size: 66x40x10mm\r\nDisplay area size: 32x23mm\r\nExternal normal Sampler Size:23x18x5mm\r\n\r\n​\r\nTechnical Parameters:\r\nWorking power consumption: 8.0mA (Max:10.0mA)\r\nStandby power consumption: 0.5mA (Max:0.8mA)\r\nSleep power consumption: 50uA (Max:60uA)\r\nVoltage acquisition accuracy: +/-1.0%\r\nCurrent acquisition accuracy: +/-1.0%\r\nUsing ambient temperature rang: 0-35C\r\nBacklight on current: 40mA (Max:50mA)\r\nBacklight off current: 30mA (Max: 40mA)\r\nBattery capacity setting value: 0.-590Ah\r\nBuilt-in sampler working current: 5.0a (Max:10.0A instant)\r\nExternal normal sampler working current:30.0A (Max:50A)\r\nExternal big sampler working current:50.0A (Max:100A)\r\n\r\nAttention:The min voltage of the battery pack should higher than the min working voltage of the coulometer\r\n\r\nFeatures:\r\n1.The empty and full voltage of battery can be adjusted\r\n2.The backlight automatic open when using\r\n3.Automatic memory function when power down\r\n4.Fast response rate\r\n5.Low power consumption, automatic wake-up\r\n\r\nDisplay:\r\n1.Residual capacity of battery (Ah or mAh)\r\n2.Capacity percentage and totem pole display\r\n3.Battery voltage\r\n4.Battery current\r\n5.Powe output\r\n6.Remaining for time of charge and discharg\r\n\r\nPackage include:\r\n1 x 50A Battery Tester\r\n1 x Shielded Wire\r\n(If you need instructions, please contact us and we can send it by e-mail)\r\n\r\nNote:\r\nItem color displayed in photos may be showing slightly different on your computer monitor since monitors are not calibrated same.\r\nPlease allow 1-3mm slight deviation due to manual measurement.
