    Cześć Tomasz, Dziękuję za Twój komentarz. Niestety, urządzenie nie rejestruje danych do eksportu. Możesz jedynie zapisywać obrazy ekranu i je przesyłać. Okres próbkowania funkcji wykresów wynosi około 80 ms. Tak więc, funkcja wykresów jest przydatna jako wskaźnik, ale nie oferuje bardziej szczegółowych możliwości rejestrowania danych.

    Thank you for your comment but I disagree with your explanation. Since the multimeter has a memory of 10,000 readings, it was designed to store data. Otherwise it wouldn't make sense. It is likely that access to these registrations may be a route similar to software updates. I hope that soon we will learn how these registrations can be copied to a PC and then visualized, e.g. using Excel.

    Hello, In the specification of a multimeter, the "10,000 counts" refers to the maximum display resolution of the meter. This means the multimeter can display readings up to 10,000 discrete values. For example, if the multimeter is set to measure voltage in the 10V range, it can display values from 0.0001V to 9.9999V, providing a very fine resolution of measurement. It does not refer to the amount of readings the multimeter can store in memory. Instead, it indicates the precision of the readings the multimeter can show. So, a 10,000 count multimeter can show readings with a higher level of detail compared to a 2,000 or 4,000 count multimeter.

    Please ask FNIRSI to add Hz and Ohm to the Thresholds ;-) Very Informative! There are more Infos to CAL Mode?

    Hello, happy that you found the video informative. That is a very good suggestion on the thresholds. I will feedback the point to them. No more information on the calibration mode. There is also a similar mode on the 2C23T (see my functional review on it). I did ask FNIRSI for more information on the calibration mode, however they declined as it is meant only for their internal production process.

    Please ask FNIRSI to add volume setting. Like HS-02 iron

    Good point, although given the type of buzzer, they may be limited by what can be done to control the volume (hardware limitation).

    FYI: Update does not work if using Windows 7 Pro. Windows 7 apparently doesn't recognize the file system and is asking to "format" the drive so I opted out of that option. I will try on a Windows 10 system and hopefully have some luck there.

    I do have the same problem on my W7 pro PC it does not work, asks always to format the file in FAT16 modus. I will try it on my W10 PC .
