The compact tester KCX-017 is designed to measure the output voltage in the USB ports of computers, laptops, chargers, power adapters and other devices with a USB output. Measurement of the charge current of powerbank, phones, tablets and similar devices. Measuring the amount of energy consumed by devices. Definitions of battery capacity and powerbank. The KCX-017 tester will help identify a faulty USB cable or charger, find out the actual battery capacity.
KCX-017 compact USB tester for checking USB wires, measuring current, voltage, battery capacity, characteristics, mode control, overview.
The KCX-017 compact USB tester can measure current, voltage, displaying their values on a liquid crystal display, and count the electric charge energy passing through it, thus determining the battery capacity and writing these values to one of ten cells of its non-volatile memory. On the front panel of the USB tester KCX-017 there is a button for switching cells and their zeroing. On the back of the case are the technical characteristics of the device, as well as holes for cooling the device. The KCX-017 tester has one USB cable and two connectors.
charger or other device. After connecting, the LCD turns on and the current voltage measurement begins. You can connect the tester not only through its built-in USB cable, but also to its micro-USB port via the appropriate cable.
After connecting the consumer to the KCX-017 tester, as soon as the connected device starts to draw current, the measured value of the current strength in amperes and transmitted energy, in milliamperes per hour, will be displayed on the liquid crystal display. After connecting the load, the input voltage value will sag, the degree of its drawdown will depend on the quality of the connecting wires and the power of the power source. If the supply voltage is lower than 4.7 Volts or higher than 5.3 Volts, the LCD will flash. This does not affect the use and performance of the tester..
Determining battery capacity using the KCX-017 USB tester.
There are two ways to determine the battery capacity of a mobile device or powerbank.
1. Completely discharge the tested battery, reset the value of the selected cell of the KCX-017 tester, connect the tester to the charger and the tested battery in series. Then, after fully charging according to the indicator of the device whose battery is being checked, read the capacitance values from the tester display.
2. Determine the capacity of the battery according to the same principle, but not charging, but discharging it.
Checking the health and performance of USB wires using the KCX-017 tester.
It is made by comparing the values of the passing voltage and current when connecting various USB wires to the tester with the same power source and the same load.
The USB tester KCX-017 works with the solar panel when charging mobile device batteries.
On the performance of a solar panel operating as a charger, its location relative to the Sun is of great importance. Observing the voltage and current values on the USB display of the KCX-017 tester, you can orient and install the solar panel so that its efficiency is maximum.
USB Mode Control KCX-017.
It is carried out using the button, which is located on the front side of the tester at the display. Using this button, you can switch between ten memory cells, as well as reset the results of energy consumption data stored in memory. A single cell may contain capacitance values from 1 to 19999 mAh. The memory of the KCX-017 tester is non-volatile, and all data in it can be stored after turning off the power. If during the measurement you turn off the supply voltage and turn it on after a while, the calculation of the consumed energy will continue from the point where the power was turned off.
Switch between memory locations 0 to 9.
Double-click on the button, the display should start blinking. After that, each single press will switch to the next cell without resetting the current cell. The next double click on the button activates the exit from the switching mode between cells.
Reset the values of the capacity recorded in the memory cells.
It is done by holding the button for more than five seconds and resets the recorded value of the next in order memory cell. If it is necessary to erase the data of cell No. 2, hold the button down when cell No. 1 is displayed. After five seconds of holding, the memory in cell No. 2 will be erased and it will automatically go to it.
