Features： 1、Bidirectional Detection of Current: Detection of charging and discharging users can easily detect bidirectional current without changing the wiring direction. Adopt high performance DC Hall sensor to collect current, safe, convenient and accurate. 2、Power Failure Memory Function: After power failure, the ampere hours before power failure can be remembered, which is convenient for observation and measurement. The number of amp hours can be filled or cleared with one key, which does not affect the direct charging and discharging measurement. 3、Comprehensive Display: Voltage, current, ampere hour, watt hour, time, power and temperature are displayed simultaneously, displaying comprehensive and clear information. With output shutdown function key, flexible to turn on or turn off the output. 4、Multi Protection: With over voltage, over current, over power, under voltage protection and temperature control functions. It can be calibrated online, which is convenient for customers to correct the error in time. LCD screen can realize auto off and auto on to reduce product power consumption. 5、Sound Alarm: The voltage and current waveform display function can be switched to observe the change curve of voltage and current more intuitively. Relay port can be switched to buzzer port to realize sound alarm function. 6、Auto Correction: Under voltage capacity can be automatically cleared to 0, over voltage capacity can be automatically filled to facilitate long term cycling of customers, and auto correction error. Specification： Item Type: Coulombmeter Model: VAC9610S Material: ABS, PCB Measurement range: Voltage: 0.01-500v Current: 0-1000A Capacity: 0.001AH-65000AH Energy: 0.00KWH-99999.9KWH Time: 0-100 hours Power value: 60KW Temperature: 1-100 degrees Celsius Accuracy: Voltage: ±1% Current: ±2% Temperature: ±2℃ Measurement rate: 20 times/second Protection type and range OVP (over voltage protection): 0.01-500v LVP(under voltage protection): 0.01-500v OCP(charge overcurrent protection): 0-1000A NCP(Discharge overcurrent protection): 0-1000A OTP(Over temperature protection): 0-100℃ Function introduction: 1, "BAT" battery capacity value setting, this parameter is to set the total measured battery capacity. 2, "BPC" battery remaining capacity percentage, you can set the remaining AH of the battery according to this value. 3, "OPP" set the over power protection value, if set the OPP value, when the actual output power value is greater than the set value, will prompt over power, and cut off the relay (self assigned). 4, "OVP" set the over voltage protection value, if set the OVP value, when the actual measured voltage value is greater than the set value, it will prompt over voltage, and cut off the relay (self contained). 5, "LVP" set the overvoltage protection value, if set the LVP value, when the actual measured voltage value is less than the set value, it will prompt the undervoltage, and cut off the relay (self assigned). 6, "NCP" set the overvoltage protection value, if the NCP value is set, when the actual measured charging current value is less than the set value, it will prompt overcurrent, and cut off the relay (self contained). 7, "OCP" set the overvoltage protection value, if the OCP value is set, when the actual measured discharge current value is less than the set value, it will prompt overcurrent, and cut off the relay (self assigned). 8, "OTP" set the over temperature protection value, if set the OTP value, when the actual measured temperature value is greater than the set value, will prompt over temperature, and cut off the relay (self assigned). 9, "ADS" communication address setting. Multi computer communication by setting the address to achieve multi computer communication. 10, "TTL" instrument power on the default relay output state, normally open or normally closed. 11, "CLR" no load current clear function, if the actual no load current is not 0, use this function to clear the no load current to 0.
