For measurement, the device need to connect between the power source and the consumer.
How to use USB tester KCX-017 manual:
You need to connect it between the power source and the load (consumer). The display will begin to show the current voltage and current, as well as the capacitance that has been calculated by the device after you connect it.
The results are managed by pressing to the round button near the screen:
- it can be switch from 1st to 10th capacity value.
- for deleting the result.
To view the results,
you need to quickly press this button twice, the tester will enter in the display mode (the display will blink) and show the first result. If you press once it will display the next result. And so on to the last value. To exit this mode, you need to press the button twice briefly.
To delete the results,
hold down the button for more than 5 seconds. This will delete data from the next data cell, but not the currently displayed cell . To delete, for example, data from the 4th cell, you need to switch to the 3rd and hold down the button for more than 5 seconds. Data from this cell will be deleted.
KCX-017 review:
I really liked this device, it is need for any activity with electronics very often. Basically, I use it to calculate the real battery capacity of a mobile phone. Lightweight, compact... You can find out the real capacity of a power bank, any battery, find out what the maximum current a wire or cable can withstand. Shows actual voltage and current flow. Its display is small (27mm by 8mm), but everything is clear and visible. I used it gently, but sometimes I dropped it sometimes. Neither the display nor the case was damaged! The plastic is high quality and non-toxic. I have this device for over two years and has never let me down. I used it often, checking each mobile phone for current flow and for measure of battery capacity, and there were a lot of mobile phones. For such little money, the KCX-017 tester is recommended by myself for purchase.
How to check real battery capacity in mobile phone?
To find out the exact, real battery capacity of a mobile phone, you need to discharge the phone to 0% and, without turning it on, connect it to a USB multimeter. And go mind your own business. When the phone is fully 100% charged, you need to look at the capacity value in the corner of the screen. Attention! This capacitance is calculated for the voltage of the charger, not the voltage of the phone's battery!!! if the tester showed a capacity of 2500mAh, at a voltage of 5.2V, you need this capacity recalculated as follows:
Battery real capacity = Tester voltage / (divide to) your Battery voltage (4.2V for lithium) (multiply) * Tester capacity value.
In the event of a short circuit the KCX-017 USB tester does not break, apparently goes into protection mode.
This is inside view of the tester.
In general, I am satisfied.
You can buy USB tester KCX-017 with free shipping without worry. The rating is high. I recommend!
Advantages:
- Compactness, durability, measured values are close to real, short circuit protection, non-volatile memory up to 10 cells for capacity, and it is very important - low price.
Cons:
- I did not find them. Have fun using this indispensable device!
