White -tailed LCD backlit LCD digital screen shows USB current meter…

Warm reminder:

1. This baby has been corrected by the factory, and you can use it immediately after you get it!

2. A protective film on the screen. After you tear it, you can see the smooth screen surface.

1. Product characteristics:

At the same time display voltage current and MAH data, which is convenient for viewing

You can detect mobile power output MAH

Multiple sets of detection data are saved, and the power is kept and savedFunction

Do not affect data transmission

The accuracy is higher, and the current parameters will basically not jump messy

USB male and MicroUSB port dual power, which can detect MicroUSB line quality

Current sampling 25 mm euros, smaller loss

With precision current calibration function, the current accuracy is higher (it has been calibrated at the time of delivery)

2. Performance parameters:

Input voltage:3V-7V (can be within 12V in actual 12V)

Voltage resolution: 0.01V

Test current:0.05A-3.50A

Current resolution: 0.01A

Capacity range: 0-19999mAh

Accuracy: positive and negative 1%

Line loss: about 0.1 Euros

Test content:Battery voltage, current, discharge capacity (in total10Group data)

3. Function introduction:

3.1, voltage current:

The USB male head plugs in 5V charger, mother seat plug -in mobile phone and other devices, and reads voltage current parameters directly.

3.2, measure the quality of MicroUSB line:

The mother seat plug -in mobile phone and other equipment, first insert the 5V charger with the male male, remember the voltage, and then use the Microsb wire to insert from the 5V charger to the MicroUSB hole in this machine to remember the voltage. The smaller the voltage gap, the better the MicroUSB cable quality, the better the qualityEssence

3.3, measure the output capacity and efficiency of the mobile power supply:

First connect to the mobile power supply, turn on the mobile power, and press the key until the capacity data is zero. Put the mobile phone and charge it multiple times until the mobile power supply is automatically turned off automatically.The display capacity when opening the machine next time is MAH output by the mobile power.Note that this MAH is far smaller than the nominal MAH. The output MAH*output voltage 5V/battery MAH*battery voltage 3.7V = mobile power efficiency.

3.4, data switching:

Click the button to switch to the next set of data, and double -click the button to switch to the previous set of data.

3.5, data clear zero:

Press the button for more than 3 seconds to clear the data of the group.

4. Application example:

4.1. Test the charging voltage and current of electrical appliances such as mobile phones, tablets, mobile power, etc.:

The detector USB male head plug in 5V usbCharger, mother seat plug in mobile phones, tablets, mobile power and other equipment, and directly read the voltage current parameters.

4.2. Test the output voltage and current of the power supply, the mobile power supply (must be matched with the load):

The detector USB male head plug in 5V usbCharger, the mother seat inserts the USB loader, and reads the voltage current parameters directly.

4.3 Test the voltage drop of the MicroUSB data cable to compare the over current capacity of various wires (must be matched with the loader):

The USB man in the measured data line plug it in 5V usbCharger, MicroUSB male head plugs into the MicroUSB mother seat of the USB detector, the USB mother seat of the USB detector is inserted into a USB loader, and the voltage current parameters are directly read.

4.4. Test the output capacity of the mobile power supply (must be matched with the load. Pay attention to the word "output". The test tested here is not the capacity of the mobile power.The capacity of the mobile power nominal refers to the total battery capacity in it, which is much larger than the actual output capacity!Customers who do n’t understand, please search by yourself):

Fully charge the mobile power supply, insert the USB male head on the mobile power supplyThe mother seat is inserted into the USB loader and adjusts it to the 1A gear, and it has been discharged to the mobile power to automatically shut down (be sure to pay attention to the heat dissipation of the load!), At this time, the MAH data recorded is the output capacity of the mobile power supply.

A mobile power installation three -section Samsung 2600mAh battery (total capacity is 7800mAh), the EBD discharge result is 6108mAh, and the USB detector detector test results are 6117mAh, which proves that the capacity test of the detector is quite accurate!
