Multi-function Volt-ammeter 1.8 inch LCD Display Voltage Current Instrument with Power Off Memory Function

It is a basic multi-function instrument that can display various kinds of parameters such as display the voltage current power capacity energy temperature running time and other physical parameters in real time. Over-voltage under-voltage over-current and over-temperature protections can be achieved through reserved relay interfaces. And the meter uses 1.8-inch color LCD as display display data more comprehensive and clear easy to observe. This meter is perfect for applications that require monitoring of the output voltage and current as well as and discharge batteries. Features: Bidirectional current detection for detecting and discharge users can easily detect bidirectional current properties no need to change the direction of the connection. Power off power memory function after power off the number of AH and WH before power off can be memorized convenient for observation and measurement. Time and AH data clearing function do not affect the measurement later. The percentage of AH can be set without affecting direct discharge measurement. Voltage current AH WH time power simultaneously displayed comprehensive and clear information display. With output disconnect function key flexible on or off output. With over-voltage over-current over-temperature and other extended-protection functions. It can be calibrated online enabling customers to promptly correct the error. In the liquid crystal display can be closed when necessary reduce power consumption. Function Introduction: 1. BAT battery capacity value setting this parameter is to set the battery measured total capacity. 2. BPC battery remaining capacity percentage can be set according to the value of the remaining battery AH. 3. OVP set over-voltage protections 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-provisioned). 4. LVP set overvoltage protections value if you set the LVP value when the actual measurement of voltage is less than the set value it will prompt the undervoltage and cut off the relay(self-provisioned). 5. NCP sets the overcurrent protections value. If the NCP value is set when the actual measured charging-current value is greater than the set value it will prompt overcurrent and cut off the relay(self-provisioned). 6. OCP sets the discharge overcurrent protections value. If the OCP value is set when the actual measured discharge current value is greater than the set value an overcurrent will be prompted and the relay(self-provisioned) will be cut. 7. “OTP” sets the over-temperature protections 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(self-provisioned) will be cut off. 8. ADS communication address code setting.In multi-machine communication multi-machine communication is achieved by setting the address code. 9. TTL instrument powers up the output state of the default relay normally open or normally closed. 10. CLR no-load current correction function if the actual load current is .
