2.Mobile power output MAH can be detected.
3.Does not affect the data transmission.
4.With precision current calibration function, the current accuracy  is higher(it has been calibrated when shipped)
5.Smaller loss .
6.Save multiple sets of test data, power-down save feature
7.Higher accuracy, the current parameters of the basic will not bounce
8.USB and MicroUSB port male double take power, can detect MicroUSB line quality
 
Measuring voltage and current:
USB male plug in 5V the charger, female plug in mobile phones and other devices,readout voltage and current parameters directly

Clean the data: Push the button until the parameters changed to next sets of parameters. Then release the button. Then the next sets of parameters will be started and they will start from zero.

Check the parameters: Quick beat the button double times(within 0.5s), then it is checking model. The LED background will be flash.Then you can see the next set of parameters in LCD screen. Quick beat the button double times agian, you release the parameters checking model. LED backgroud be light with flash.

Over voltage or under voltage: An arrowhead will be shown in LCD screen and LED background will flash. Push the button and LED will be light without flash. It will last 30s.    

Package Included:    
1 x USB Current Voltage Meter
1 x 1A/2A Discharge Load Resistor
