OLED COLOR :WHITRE This product is USB a perfect function of detection and control instrument. The measurement accuracy has reached as high as 5, USB can measure the output voltage, current, power, Watts, power and other parameters. At the same time can be calculated with load time, with temperature measurement function. The display with a wide visual angle liquid crystal display OLED effect is far. In the LCD screen poor visual effect.
The product is compatible with USB2.0 and USB3.0 model. The maximum input voltage 24V. therefore improve the support with QC2.0 QC3.0 function of the charger. The fast charge mode, smart chip can simulate the mainstream mobile phone such as apple, Samsung mobile phone is usually in order to determine whether the original charger, this instrument can be disguised as the original charger, so that the mobile phone to open the charging current (Note: the new mode of charging current depends on the front end of the output current, the instrument does not make the current increase). Voltage instrument can display the data line, you can also observe changes in voltage protocol! After setting the data line, optional fast charge, straight, suspended three modes of detection and protection function! Header rich, perfect monitoring equipment parameters of the battery. You detect charging treasure your actual capacity is accurate and reliable. According to the need to buy our patented USB resistance lines Measuring accessories, precise measurement of line resistance, accurate to 1 cents in Europe. To achieve the industry's high level!
As a specific practical product, the hardware design of the meter adopts 22 professional AD chip, ensures the high accuracy of the measurement results. You can record the last 10 kwh, the output capacity of group, 1 groups of separate time. Record the last 10 groups. Accumulated data storage algorithm advanced in each record, when the power off time the current data. To avoid similar products at any time to write too much frequency and damage the memory chip and cannot record the shortcomings.
The instrument operation using the system menu operation, professional team customization system, computer management, double design, excellent operating experience, do not need to memorize complex operations, WYSIWYG. At present similar products are basically a single, great difficulty in the operation, need to remember complex order, you need to read the instructions before the operation. This product has the Chinese and English language, only can be modified in the system settings. For friends around the world. 
1 Why is the 1 meter voltage display voltage and power I on, to a low point, if the load is low, the more? This phenomenon normal? Answer: This is normal, because from the power supply to the head of the middle section of the line, if the line is long, the more fine, the voltage will drop more because the wire is resistance, when the current is large, the above pressure drop is greater so try to use thick, short wire. To reduce the pressure drop, but also reduces the wire loss!
2 why to my cell phone charging, some time ago the current display is very stable, fast full time current will appear suddenly big suddenly small change? Answer: because the beginning is usually charging, constant current charging, fast full, will be transformed into the charging pulse, this is the actual changes inside the mobile phone charging current of the battery has been filled with some mobile phone and mobile phone charging will not change, the instrument design just measuring. .......................................................................................................................................................................................... USB interface uses tips: USB socket for a long time, there will be some bad contact, voltage is always changing, you can add a little butter or oil on the socket, repeatedly inserted several times, the contact is very good.
