  • Voltmeter Range: DC 0-100V ; Ammeter Range: DC 0-9.99A.
  • Voltage resolution (V): 0.1V;Current resolution (A): 0.01A
  • Working voltage of Meter itself:DC 4 - 30V(The maximum input voltage can not exceed 30V. Otherwise the meter will be burned)
  • Display: Dual 0.28" three digit Red/Blue LED tube, very bright and clear.
  • Measure accuracy: 1% (± 1 digit)

Features:

  • Working voltage of Meter itself:DC 4 - 30V
  • Working current of Meter itself:≤20mA
  • Voltage Measuring range: DC 0 - 100V
  • Current Measuring range: DC 0 - 9.99A
  • Voltage resolution (V): 0.1V
  • Current resolution (A): 0.01A
  • Measure accuracy: 1% (± 1 digit)
  • Display: 0.28" digital tube, Two color blue and red
  • Refresh rate: about 300mS / times
  • Dimensions:48mm*29mm*26mm
  • Operation Temp: -10℃-+65℃

Wire Connection: 

  • Thin Red line (VCC): Power Supply + (DC 3.5-30V +) 
  • (if the measure voltage between DC 3.5-30V, then the Thin Yellow line and Thin Red line can connect together) 
  • Thin Black line (GND): Power Supply - (DC 3.5-30V -), Measure Voltage - (DC 0-100V -) 
  • Thin Yellow line (VIN): Measure Voltage + (DC 0-100V +) 
  • Thick Red line (I+): Current Input + 
  • Thick Black line (I-): Current Input - 
  • More detail please check the description picture. 

Error Phenomena:

  • Due to the aging of the device and change of ambient temperature 
  • The error becomes larger when measuring small current. 
  • Solution: When there is no load, short-circuit 2 pads of KEY and then power on, the module will automatically do zero calibration, after that shut off the module and cut the short circuit point. 
  • The error becomes larger in whole measurement range 
  • Solution: When connecting load(half of the range is best), keep adjusting R7 until it displays the same value with the more advanced calibration source.
