Program that can log from many multimeters.
« on: March 25, 2020, 10:48:51 am »
I have been working on a program that can log from multimeters, electronic loads, power supplies and some other stuff. The program can log, show charts and do math on data from multiple devices simultaneous.
The program works on Windows, Linux and Mac.







Read more about it and download it from here: http://lygte-info.dk/project/TestControllerIntro%20UK.html

If anybody have ideas about how to log from USB/HID connected meters, please tell. I have played with a Brymen, but it only works on Windows.

Many SCPI devices can fairly easy be added to the software by anybody, but I have not written the documentation for it yet.
It is, of course, possible to check my definitions and use them as basis for a new definition.
What I suggested on BLF was to use the 34465A definition as basis.

If somebody makes some good definitions for equipment, please mail it to me and I will include it with the software. There is a trick with the definitions to make many similar ones, I use it with the electronic loads and some multimeters (In reality I only have two Keysight multimeter definitions, all my other Keysight multimeters used on or the other of these two protocols).

The BLF is budgetlightforum and my posting is here: http://budgetlightforum.com/node/72218

I have been working on a program that can log from multimeters, electronic loads, power supplies and some other stuff.

It is still an alpha version, but it works fairly well. I am interested in comments, ideas and error reports.
(..)

If you want to go serious on that check sigrok code base

95% of the grunt work is done like error handling
and protocol handling including multiple paths and sessions.
https://sigrok.org/wiki/Supported_hardware

Not so hard to do but hard to jump in easily.

After the learning curve things are just on other level
of functionality (i've been there as well )

I am not that impressed with the amount of equipment they support and they uses the wrong language.
What I need is logging from all my equipment and a easy way to switch between different brands of equipment. With the current software I have been logging from 10 devices simultaneous to the same table and chart with 1 seconds intervals.

Maybe it is a bit hard to start with the program, the way to get devices(multimeters) into the program is rather discrete.

At the bottom of the "Load devices" page, use this:



To select and added devices.


I have added a popup on the "Load devices" page that says to use combox and add button, it will only show it the page is empty.

Not sure if helps but the amount of hardware is bounded
just by the proper interface with the API.

The API itself is *quite good*.. 

While doing some checks against my own widget toolkit
it took me about 5 to 7 days to craft those simple tools...

A fully functional DMM applet
and  a fully function  SCOPE / FUNC.gen with channel modulators...

ALL GTK BASED  compiled against libsigrok.

Hard to start on the API but once managed... it is good

These ARE JUST MY TOYS... not serious things just tests.

minor shots below.

Hi, Interesting software.

> Type in serial port or IP address and for some devices a baudrate.

Does that include USB serial connections? In other words can I connect over USB? Instrument is a Keysight 34465A.

I'm asking before I go ahead and install Java on this machine, which doesn't have it. I also don't have ethernet, so prefer to use USB if possible.

If the USB interface creates a virtual serial port it will work. I have only used 34465A with a socket connection and you cannot select serial port for it, but if you checkmark the "Scan serial port" it might work. (The scanning function will check against all devices ignoring the specified connection type).

Thanks for all the work!

I've been logging for 24 hours straight and this thing is rock solid. Haven't gotten the delay commands to work yet so switching the operating mode isn't happening for me.

Just testing a bit.
"Voltcraft VC-940" should read "Voltcraft VC-940 COM"
since Voltcraft VC-940 USB HID is not supported. Helps to avoid confusion as to the two different interfaces.

Sometimes a second instance of the program needs to be started to fill "Search socket" with the equipment list.

dB mode of the 34465A is not supported (yet).

I attempted to load a CSV from my own logging program just to check yours out and for some reason it truncates all readings to 2 digits. Even after setting it to 8 digits for those columns it doesn't update even when reloading the same CSV again. I'm assuming it refuses to plot those numbers since they look the same once loaded due to the truncated decimal digits.

That might be a good idea.

Strange, it only loads a directory, I wonder hot it can fail.

dB mode of the 34465A is not supported (yet).

It is not a native measurement mode, but a calculation (I may look at it at some point).
It is always possible to add dB or dBm to any measurement by using the Math functions. It has log() for 10 based logarithmic and ln() for e based logarithmic.

I launched the program for DMM7510. I managed to connect. But I did not understand what I need to click next to get some kind of graph or where to find the range control, etc.

I attempted to load a CSV from my own logging program just to check yours out and for some reason it truncates all readings to 2 digits. Even after setting it to 8 digits for those columns it doesn't update even when reloading the same CSV again. I'm assuming it refuses to plot those numbers since they look the same once loaded due to the truncated decimal digits.

The decimal settings are only for scales on the charts. Generally it will match column names to its internal list of devices and if there is a match it will use the decimal settings for that column, when not it uses 2 decimals.

Internally it will always use the full resolution (All storing and calculations are done with double precision).

Maybe I need to add a configuration for decimals on unknown columns.

The problem with plotting the columns are due to the spaces in the column names. I will do something about it.

For bench DMM's you only have a mode button that can select between modes (VDC/VAC/ADC/etc), it do not do more detailed settings, there you have to type SCPI commands (They can be assigned to hotkeys).
Before you can do anything with a device it must be selected. When starting the program it will automatically select one device, but when using "Reload" it will not. To select a device right click left of the command line, near the colon.

To get data for charts you have to do some logging, press the "log" button and select a time interval, after a few seconds the chart, histogram and range pages will be available.
Without logging you can only see data from the meters on the "Current values" page.

The choice of ranges and modes was not available. Does this mean that I did not connect correctly?

Got it, replaced the space with an underscore(odd limitation, usually for CSV's I pull the entire string between delimiters). Still can't use the plotting for readings however. When I range limit to the min/max of real readings I get no plot just the scale, and obviously when I let it auto it's just a straight line at the top of the graph. Alternatively I'm not sure auto min. range and auto bottom step are meant to do. I feel the results I'm getting are a bit random.

It list all connected devices in the bottom window, it is is there it is connected.

This is because the column names are variable names when you do math. I have modified it to accept spaces and then automatic replace them with _ when creating variables (New version will be uploaded later today).

Still can't use the plotting for readings however. When I range limit to the min/max of real readings I get no plot just the scale, and obviously when I let it auto it's just a straight line at the top of the graph. Alternatively I'm not sure auto min. range and auto bottom step are meant to do. I feel the results I'm getting are a bit random.

When Auto is checked Minimum/Maximum is ignored.
These 3 setting is only active when auto is checked:
Auto includes zero means that auto scales will include a 0 value, this will block for seeing small changes in a large value.
Auto min. range defines the minium span that can be used on a chart (in auto), this is used to avoid amplifying noise to fill a full chart height.
Auto bottom step is the step size for the bottom of the scale (0 is legal), this can be used to make scales align.
