["Features:\r\n1.MULTIMETER: this multifunctional meter can measure for DC voltage, current, power, charging capacity, for time, and other physical quantities at the same for time; can be directly used, no need shunt. \r\n2.MEASURE RANGE: Digital multimeter can messure voltage range for DC 0-90V, current range 0-20A, power range 0-9.99KW, capacity range 0-999Ah, for time range 0-99.9 hours. \r\n3.LCD COLOR DISPLAY: the voltage current power panel gauge adopts 1.8 inch LCD color screen, can be seen even under sunlight; LCD display will automatically turn off after two minutes if current less than 50mA, pressing any for key can turn off, or it will wake up automatically when the current is greater than 50mA. \r\n4.DATA STORE: The battery tester can automatically save the parameters when the display power off; if the monitor module also needs to power off, press OK button can save the parameters. \r\n5.BIDIRECTIONAL DETECTION: it's bidirectional, can detect and display current of charging and discharging. Note: it can not detect current of two directions at the same for time. \r\n\r\nParameters:\r\nVoltage Measurement Range: \r\nSelf-supply Power: for DC 10~90V\r\nExternal-supply Power: for DC 0~90V\r\nCurrent Measurement Range: 0~20A\r\n\r\nDisplay Resolution:\r\nVoltage : 0.01V\r\nCurrent : 0.01A\r\nfor Time : 0.01H\r\nCapacity : 0.01AH\r\nCurrent Precision: ± 1% + 2 digits\r\nVoltage Precision: ± 2% + 5digits\r\nMeasurement Rate: 5 times/sec\r\nVOP( Over-voltage Protections): 0.01V~90V\r\nOPP( Over-power Protections ): 0.01W~9.99KW\r\nOCP( Over-current Protections ): 0.1~100A\r\nOAH( Over-AH for Protection ): 0.01AH~9999AH\r\nOFT( Over-time for Protection ): 0.01H~99.9H\r\nOpen Holes (mm): 76.5*39.2（mm）\r\nSize: 79×43×52(mm)\r\n\r\nNote: There is no relay with this version, therefore, LOP(low voltage for protection) function can not be used.\r\nWe have more detailed user manuals.
