Feature:1. Two-way detection of current is very convenient for users to detect charging and discharging, without changing the wiring direction2. Power-off memory function, after power-off, the AH and WH numbers before power-off can be memorized, which is convenient for observation and measurement3. Time and AH number reset function, does not affect the another measurement, AH number can be topped up, does not affect direct discharge measurement4. Voltage, current, charging capacity AH number, WH number, time, power are displayed at the same time, the display information is comprehensive and clear5. LCD Voltage Current Combo Meter has an output shutdown function key, which can flexibly turn on or off the output, and has protection functions such as overvoltage, overcurrent, and overtemperature6. The power meter not only can be calibrated online, and convenient for customers to correct errors in time, and the LCD display can be turned off when necessary to reduce product power consumption.Specification:Item Type: LCD Combo Meter VoltageMaterial: ResinInput VoltageMeasuring Range When Self-Powered: 6-75VMeasurement Range When External Power Supply: 0-120VExternal Power Supply Voltage: 6-60VDisplay Mode: 1.8 Inch LCD DisplayMeasuring RangeVoltage: 0.01-120VCapacity: 0.001AH-65000AHEnergy: 0.00KWH-99999.9kWhTime: 0-100 HoursPower Value: 99KWTemperature: 1-100 Degrees CelsiusAccuracyVoltage: 1%Current: 2%Temperature: 1 Degrees CelsiusMeasurement Rate: 5 Times/SecType and Scope of ProtectionOVP (Over Voltage Protection): 0.01-500VLVP (Undervoltage Protection): 0.01-500VOCP (Charge Overcurrent Protection): 0-1000ANCP (Discharge Overcurrent Protection): 0-1000AOTP (Over Temperature Protection): 0-100 Degrees CelsiusFeatures1. "BAT" battery capacity value setting, this parameter is to set the measured total capacity of the battery.2. "BPC" battery remaining capacity percentage, you can set the remaining battery AH number according to this value.3. "OVP" sets the over-voltage protection value. If the OVP value is set, when the actual measured voltage value is greater than the set value, it will prompt over-voltage and cut off the relay (self-distribution).4. "LVP" sets the overvoltage protection value. If the LVP value is set, when the actual measured voltage value is less than the set value, it will prompt undervoltage and cut off the relay (self-equipped)5. "NCP" sets the over-voltage protection value. If the NCP value is set, when the actual measured charging current value is less than the set value, it will prompt over-current and cut off the relay (self-equipped)6. "OCP" sets the over-voltage protection value. If the OCP value is set, when the actual measured discharge current value is less than the set value, it will prompt over-current and cut off the relay (self-equipped)7. "OTP" sets the over temperature protection value. If the OTP value is set, when the actual measured temperature value is greater than the set value, the over temperature will be prompted and the relay will be cut off (self-equipped)8. "ADS" communication address code setting. In multi-machine communication, multi-machine communication can be realized by setting the address code differently.9. "TTL" The default relay output state when the instrument is powered on, normally open or normally closed.10. "CLR" no-load current clearing function, if the actual no-load current is zero. 11. "DTE" screen time setting, if this time value is set, the meter will automatically turn off the screen and press the OK button to automatically light up..Package List:1 x LCD Combination Meter 2 x Wiring1 x User ManualNote:Note: The working power of the relay is provided by an external power supply. If the relay is connected, an external power supply with the same working voltage as the relay should be provided, and the power supply status of the instrument should be adjusted to the state of "3w" Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-Minnanxin
