Android Software
First you can see the continuous graph representation. Especially since the whole thing can also be used via Excel table as output of the data logger. Then the display with current and voltage follows. In addition, you can also see the internal resistance of the USB voltage source. On the right, the capacity or the charged energy is displayed. In addition, as in this case "DCP 1.5A" the loading protocol is displayed. You can use sliders to adjust the brightness of the (mobile) display and the time when the screen protection starts. You can also set which (charging) current is switched off.
The four buttons are designed to control the UM25C itself. So turn screen, rotate and so on. The software receives regular updates and makes a measuring device from a mobile phone with the Bluetooth connection! For example, if the UM25C directly in the charger and you cannot read the display. The huge advantage: It is transmitted via BT and is therefore 100% potential-free! This is also the case with the Windows version!
Windows software
The Windows software is similar to Android. Here we see the screenshot. All of this was programmed with LabView by National Instruments. This also explains the size of approx. 290MB. It works perfectly, but the overhead of unnecessary libraries is very large. But the bottom line is something I would call "meckers at the highest level".
Otherwise, you will find all the information, just like in the Android app. Temperature refers to the temperature of the sensor installed in the device. If you want to log data with, it works on Android as well as on Windows! SO must be technology. The UM25C meets all the wishes of the e-technician heart!
Conclusion:
What is the conclusion about such a device? On the one hand, we have the technical data. We have a wealth of interfaces. We have a fantastic color LCD display. We have software for Windows & Android for potential-free measurement. We have, have, have… And what do we not have? We don't know the display resolution! We don't know the Bluetooth version! Do you need this and that?
Let's get this down on our tongues again… No, I can live damn well with the two missing technical specifications. The part falls under the term: MUST HAVE! You don't want to go without it. What you can measure: Does the mobile phone battery still have its full capacity? How big is the capacity of the 15,000 mAh power bank really? The TV Stick gets off after 30 min. Thanks to the data logger, you can easily trace everything… And, and, and…
The short form: there are endless opportunities for waste of money, but this has real added value!
