Features:This table can set the battery type by the key: lead acid battery, lithium battery, nickel-hydrogen battery, also can set the battery number by the key (battery number in series).This table is suitable for: 12V, 24V, 36V, 48V, 56V, 60V, 64V, 64V, I2V, 84V battery car, electric vehicle, battery pack, balance car, inverter, electric forklift truck, sightseeing car, electric vehicle, automobile battery battery, battery power mobile equipment, etc. It can also be used for other voltage and power test purposes.This table can be tested to show the real-time voltage, quantity of electricity, percentage of electricity.Display mode optional: single display voltage;Single display percentage of electricity;Voltage, percentage of electricity cycle display (default).Two-wire system, wide supply voltage, magic test heavy voltage: DC 6120, simple connection, convenient.With reverse protection function, the reverse connection won't burn.Low power flash alarm reminding function.LED color display, high-grade atmosphere.Specification:Power supply voltage: DC6-120 (wide range, temperament: maximum crystal input voltage can not exceed 120 V, otherwise there is a risk of burningTest voltage: DC6 ~ 120V (decimal point automatic shift)Minimum resolution below 10: Q. 1VMinimum resolution of more than 100: 1VPower resolution:1%Working current: <20mA display mode: LED color screenInstallation hole: 47.2 * 27.3 mmMeasurement rate: 500ms/ timesVoltage measurement accuracy:1% ( 2) Lead length:> 150mmMinimum supply voltage: 6VMaximum supply voltage: 120VOperating temperature:-10 ~ + 65Working humidity:10 ~ 80% (without condensation)Working pressure:80 ~ 106 kPaSunlight exposure: no direct exposurePackage List:1*Voltage Battery IndicatorNote:This watch is not suitable to be installed on the circuit with xenon lamp, the xenon lamp will have thousands of volts of high voltage in the moment of opening, there is a chance to directly burn the watch head, if it must be installed, can not be installed on the same line, the watch head should also be away from xenon lamp.Operating instructions:According to polarity, the red and black lines on the watch head will be connected to the positive and negative poles of the battery respectively. At this point, the watch head will immediately show the real-time voltage, electricity, percentage of electricityThe factory default value of this table:Battery type: lead-acid electricity, 12V, one sectionDisplay mode: power, voltage and percentage of electricity cycle displaySet mode entry:In normal mode, press the key for several seconds to enter the setting mode, display:1-U, each click to switch to the next mode key order:1-U 2-b 3-C 4-d mode:1-U: Voltage fine-tuning2-b: battery type setting 3-C: battery number setting4-d: Display mode settingVoltage fine tuning (calibration):In the set mode, press the key to switch to display 1-U, press the key to enter the voltage calibration mode for a long time.At this point release the key again long press, the voltage up fine-tuning;Loosen the key and press it again for a long time. The voltage is fine-tuned downward. After adjusting to the standard value repeatedly, loosen the key. Wait for the screen flicker to save the settings and exit the setting mode.Battery type selection:In the setting mode, press the button to switch to display 2-b, press the button to enter the battery type selection mode for a long time, each "click" will switch one battery type, the battery type cycle switch order: 1.2V _ 2V _ 3.3V _ 3.7V _ 12V1.2V: On behalf of Ni-MH battery, the single voltage is 1.2V.2V: Represents lead-acid battery, the single voltage is 2V3.2V: Represents the iron phosphate lithium battery, the single section voltage is 3.2V3.7V: Represents the polymer lithium battery, the single section voltage is 3.7V12V: Represents lead-acid battery, the single voltage is 12VWhen switching to the corresponding battery type, immediately release the button, wait for the screen flash save settings and exit the setting mode.Battery number setting:In the setting mode, press the button to switch to display 3-C, the long press button into the battery number setting mode, then release the button and press the long press again, the value jump up;Loosen the key and press it again for a long time, the value will jump down, and adjust the number of batteries repeatedly.Wait for screen flash save settings and exit settings modeThe range of adjustable "segment number" for different types of batteries is as follows:12V lead acid battery:1-103.7V lithium battery:2-283.2 V lithium ion battery:2-322V lead acid battery:3-601.2V Ni-MH battery:10-70Display Mode Settings:In set mode, press the button to switch to display 4-d, press the button for a long time to enter the display mode settings.At this point release the button, each "click" switch a display mode: V _ only display voltage,% _ only show percentage of electricity, V%-a cycle displayWhen switch to the corresponding display mode,
