FNIRSI DMT-99 Multimeter Teardown, Functional Review, and Updating the Firmware 

You are most welcome. Thanks for your kind words and I am glad you found the video interesting 😊 🙏

Your reviws is very good but for me I did't found dwo important info's: function Thems1 and 2, and most infortion how to read recorded data and speed of recording. Are this information evailable? On the Producer web page I did't this info.

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.

Thank you and glad you found the review useful.

Thanks for your comment. Yes, the 2C53P looks like an interesting product 😊

Hello, my video on the 2C53P has been published 😊

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.

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

Thank you for watching

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 .

It works on my W10 PC ok!

@@lucasbretels Thank you for confirming that.
