Although clearly designed for PX100, this works with an ATorch DL24 when paired over Bluetooth.
Perhaps the description or title can include that?

Hi, unfortunately despite many attempts I keep getting the message 'This app can't run on your PC'. Windows 10 Home 32bit 20H2, 19042.844. Maybe you have an idea how to solve this, thank you! Greetings / Rafael

With pandas 2.0 and newer:
AttributeError: 'DataFrame' object has no attribute 'append'. Did you mean: '_append'?

Resulting in a crash when connecting to the load via bt.

See stackoverflow for more details:
https://stackoverflow.com/questions/75956209/error-dataframe-object-has-no-attribute-append

As a quick fix (proved to be working) the following can be done but shouldn't according to stackoverflow:
in data_store.py line 21
self.data = self.data.append(row, ignore_index=True)
changed to
self.data = self.data._append(row, ignore_index=True)

Edit: Seems to crash again for similar reason but in main.py when doing internal resistance measurement.
However the same fix does not work here.

Здравствуйте, Михаил. Продавец Electronic_load_px100 дал ссылку на ваше ПО. Хочу попробовать его (ПО), но не могу запустить, так как командная строка в винде, а тем более в питон - густые сумерки. Вроде походил, почитал, попробовал, но никак. Win7х64 python-3.8.6-amd64. Программа ddt4all, тоже на питоне, работает.
Просьба, если не затруднит, посоветуйте что и как сделать.

Thank you very much for this great project! I was wondering if it is possible to add external temp sensor logging? I have a DL24P electronic load tester - please let me know if there is anything I can do to help / test!

Thanks again!

Any suggestion as to how to troubleshoot?

Hello,

I get a crash when starting the script.
I use python 3.8 on windows 10 and followed your instructions.
The load is conected at COM4 (USB-Serial CH340 at 3V3)

I need to change the windows regional settings to using a point, otherwise the program can only set integer numbers. Obviously a input to float conversion issue.

Михаил, добрый день!
По Вашей рекомендации с Youtube, зарегистрировался здесь, чтобы выяснить некоторые подробности и если возможно, попросить о некоторых добавлениях к возможностям программы.

Здрвствуйте!
Можно узнать об алгоритме измерения внутреннего сопротивления?
Хоть в двух словах.
Не ради интереса спрашиваю.
Во всех китайских девайсах заложен "корявый" алгоритм определения внутреннего сопротивления, измеряемого на постоянном токе. Результаты - просто жуть.
Однако есть методика измерения, описанная в стандартах (например в ГОСТ). И в стандартах измерение на постоянном токе считается более точным, по сравнению с переменным током.
Если интересует - дам и ссылки на стандарты, можно и обсудить... в питоне ничего не понимаю. но в Си - подобное делал.
Может получиться уникальная функция, которой не видел ни у кого.

When changing the setting for the current scale (default 10), the chosen value is used until the next redraw.
On each redraw it reverts to 10A, which makes the current plot pretty useless when using a low current.

I'd try to fix this myself, but I'm just getting into PyQT myself so have no idea where to start. Yet...

Hi Misdoro, i run PX100 since 1/2 year. Till now, it´s open shortly and close the program with the appended message.
Any idea ?

I try run logger but get error:

Both .exe versions are completely blocked by Chrome download.

x86 version is flagged by VirusTotal, x64 seems ok

https://www.microsoft.com/en-us/wdsi/threats/malware-encyclopedia-description?Name=Trojan:Win32/Malmsi

Kapersky thinks both are OK, so maybe false positive, but there's certainly something there that's setting off Chrome and VirusTotal

I'm having trouble getting this to run under Rasbian, Python v3.7.3. I'm no programmer by any means, any ideas on a fix?

Hi Mikhail,

Is there a way to make the software log direct to a CSV file?

I ran a couple of load tests which ran for longer then 24hrs and the program crashed and I had no record of the tests, I'm using a very basic laptop so I'm not sure if it was a out of memory issue but it would be good it does crash I have the data.

Thanks,
Chris

The control frame looks like: 0xB1 0xB2 CMD D1 D2 0xB3 0xB4

Are you sure?

My experiments show:
0xB1 0xB2 CMD D1 D2 0xB6

Hi,
I got the ACOOLOO 180W Load (DL24P) variant from amazon https://www.amazon.de/gp/product/B098FCZJJF/
So far the logging and internal resistance measurements is working fine, however I'm unable to en/disable the load via the gui, only pressing the button on the load itsself is working.

Also some small things I like to mention:

• Running on MacOS 12.5.1 (M1) for install PyQt5 was needed
• During the measurement small spikes appear (at 1A load they were between +0,1 and +0.2A) . I'm unsure weather this is a glitch in communication or actual happening on the hardware. The big peaks are from the resistance measurement.

• the x/y coordiantes on the top right are nice, but it would be even cooler if they display the voltage too and not just the current
• the Zoom to recatangle and settings for the max/min axis values are (also) resetting as in #13 described

Questions:

• what is r_a exactly? I think r_b is the internal resistance, right?

Request:

• increasing the resolution of the WH capacity (currently one decimal place, maye do the calculation in the programm instead taking the value from the board?)
• adding the external temperature sensor for battery temps (its currently only displaying the internal one)
• adding a third axis for the temperature sensor(s) and adding one decimal place as well if possible (the board got the missing decimal on display)
• is there a way to use the load for charging measuremens as well? I'm thinking about plugging an external power supply to the positive input, then the battery with plus on the negative input and the negative psu to the negative battery pole

I'm really liking your project - it makes this capacity tester at least 200% more useful! Great work!

Приветствую, Михаил!
Спасибо за отличный продукт! Удобный интерфейс и хороший функционал.
Я установил версию 64 бит под Windows 7 64 бит. Софт без проблем запустился, нашёл данные в Bluetooth и начал строить график. Но задержки обмена данными и реакции на элементы интерфейса достигают 5 - 15 секунд. Я попробовал версию x86 - та же проблема. Ноут EEE PC 1215n, загрузка процессора и памяти небольшая. Нагрузка DL24 150W

Другое приложение на ПК работает без задержек, но сильно уступает вашему софту.

Hello misdoro, I am looking forward to trying your software but maybe you can help me with a simple issue with my unit first as you know these PX100 loads well.

I have just had a PX100 load delivered but cannot seem to get the cursor to position under the "I=" current setting symbol so that I can change it to "V=" to set voltage. There seems to be nothing in the tiny leaflet that came with the unit to tell me how to do this. Going by the instructions on the sellers listing it looks as though just short pressing the top right hand "set" button repetitively should rotate the cursor position under the "I=", then the digits to set the value for current & voltage.

On this unit short pressing the "set" button only rotates the cursor under and allows to set the last 3x digits (0.00) for current ... I can't seem to be able to place the cursor under "I=" to change to the voltage setting??? Do you think this is a fault in the unit or is it me not pressing the correct key combination? .......all other menu's and buttons seem to function normally (e.g. long press "set" takes me into the setup menu and I can edit all the settings there and the rest of the buttons function normally, the voltmeter on the unit reads very accurately etc.).

Just can't get the cursor to position under the "I=" ..... what do you think? ... Thanks in advance for any help you can give.

Woops nearly forgot ... it's board version 2.81 ... software v2.45 ... :)

Hi!
While measuring a cell, it should have done every 50 mV a measurement. Hoewever it seemd to miss some results, although I heard the beep from the measurement (current change).
They are not included in the list or in the csv file. I attached the log file from some measurements.
