Generation tester Description: Size: Length Width 28MM * 60MM * 15MM thick line length: 150MM Reminder:
1， the new machine has a protective screen film， tear that is new!
2， on the recommendation of electricity with load resistance test easier to use!
3， this instrument factory has been corrected， can be used directly after receipt!
4， when the voltage is lower than 4.7V (charger output insufficient) or higher than 5.3V5 time (with line loss charger)， the LCD screen will prompt abnormal voltage flicker， flicker can not be closed.
LCD multi-function tester charge voltage and current
Electronic enthusiasts a manpower necessary artifact!
Compact and easy to carry full-featured battery capacity can test the capacity of mobile power charger USB data cable
LCD screen with backlight function， even low light conditions can also be clearly seen
Voltage and current discharge capacity USB jacks and test mobile power charger
MicroUSB data line interface test load capacity
Performance parameters:
1， the input voltage: 3V-7V
2， the input current: <3.4A
3， the test: battery voltage， current， maximum discharge capacity range z 19999MA (a total of 10 sets of data)
4， the communication function: (inputs and outputs can be used for USB communication function， that is， B + B-D + D- four-wire communication)
5， the data is cleared: hold down the button until (the first of several sets of data) into the next set and release the button to automatically skip to the next set of data is cleared
6， View: Double-click the button (0.5S or less) into the viewing data viewing mode， backlight LED flashes， and then click to display the next set of data， double-click to exit View mode， long bright LED backlight
7， voltage warning: high or low voltage， the backlight LED flashes， an alarm prompt， press the button LED lit 30S
8， powered: power via USB MicroUSB or male， the entire contents of the LCD display 1S (detection LCD screen is intact) then displays the last data (capacity and second sets of data)， current voltage， current and voltage bias high or low tips
Instructions for use:
Measuring voltage and current:
USB male plug 5V chargers， mobile phones and other equipment female insert， read current and voltage directly
MicroUSB line quality measurement:
Female plug mobile phones and other devices， first use the native male plug 5V chargers， remember that voltage， then MicroUSB cable into the bore in mind that the machine MicroUSB charger 5V voltage from the voltage the better the quality gap is smaller MicroUSB cable
Battery capacity test:
Use TP4056 and other linear charging circuit through this capacity to the table completely empty battery is fully charged to full capacity reading on the battery capacity， the use of this method can be measured charge capacity of the phone， the phone can even calculate the charging efficiency
Mobile measuring power output capacity and efficiency:
The first machine connected mobile power， mobile power turn on， long press the button until the volume of data to zero， charging into the phone several times until the move is no electricity supply automatically shut down， the next show is the capacity mAH mobile power output of this unit is turned ， pay attention to this small mAH mAH than nominal output mAH * output voltage 5V / battery mAH * battery voltage 3.7V = mobile power efficiency
Data cleared:
Press and hold the button until after (the first of several sets of data) into the next set and release the button to automatically skip to the next set of data from scratch.
View:
Quickly click the button (0.5S or less) into the viewing data viewing mode， backlight LED flashes， and then click to display the next set of data， double-click to exit View mode， long bright LED backlight.
High or low voltage alarm:
Arrow LCD backlight LED flashes， an alarm prompt， press the button LED lit 30S.
Power Status:
MicroUSB powered by USB cable or with male， the entire contents of the LCD display 1S (detection LCD screen is intact) then displays the last data (capacity and second sets of data)， current voltage， current and high voltage or bias low tips.
Calibration data set:
An electronic load device， a constant current source.
Constant current source adjusted to 8.5V and less than 10V (recommendation 9V) electronic load is set to CC mode (constant current mode) 3A， 2A， 1A， 0.3A， respectively， the four current calibration.
In 3A as an example: When 3A calibration， setting the constant current mode electronic load 3A， LCD fuel gauge current calibration automatically slowly (about 10S) can see the current will change the LCD screen， turn off the electronic load calibration automatic data protection.
