LCD Voltage Current Combo Meter Resin Energy Saving Wattmeter for Household Appliances300A Item Type: LCD Combo Meter Voltage Material: Resin Input Voltage Measuring Range When Self-Powered: 6-75V Measurement Range When External Power Supply: 0-120V External Power Supply Voltage: 6-60V Display Mode: 1.8 Inch LCD Display Measuring Range Voltage: 0.01-120V Capacity: 0.001AH-65000AH Energy: 0.00KWH-99999.9kWh Time: 0-100 Hours Power Value: 99KW Temperature: 1-100 Degrees Celsius Accuracy Voltage: ±1% Current: ±2% Temperature: ±1 Degrees Celsius Measurement Rate: 5 Times/Sec Type and Scope of Protection OVP (Over Voltage Protection): 0.01-500V LVP (Undervoltage Protection): 0.01-500V OCP (Charge Overcurrent Protection): 0-1000A NCP (Discharge Overcurrent Protection): 0-1000A OTP (Over Temperature Protection): 0-100 Degrees CelsiusFeatures 1. "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.
