Is the DE-5000 software useful?

[fishandchips]

Considering to buy the full set. Is the software useful especially in terms of measurement of inductance of D.C. Motor? Can't find any review of the software. Thanks

Sigrok supports it.

Do you mean I can just get a cable and use this software if there is a need later on? How easy it is to get such cable? Is this software as good as the stock one?

That site confuses me. Maybe I'm easily confused, and admittedly ignorant about the hole git scene. it's like aliens made this layout...

I see two links to a teardown and datasheet. The teardown comes back to EEVBLOG forum. the datasheet is a 404.

I found a small text link on the right that says serial-lcr and I can then click the text link that says blob or api.c - how utterly generic - and get some c kind of looking source code.

What I do with that? Will the Arduino IDE compile it?

I thought this device required some kind of IR-USB module, that was a black box lock unless you are a phd electchicken...

I have this meter and would like PC interface. crude is ok...

Is it worth to spend an extra of US$80 on the IR-USB module with software?

Sigrok supports it.

While that is true, we currently unfortunately have no one working on a GUI for this device class. This leaves only sigrok-cli to query device data, which means that there's no graphical display and it's up to the user to use whatever graphing tool they want to use. While flexible, it's probably not what fishandchips wants/needs.

This may of course change in the future but until someone volunteers, that's the status quo.

I bought from this guy...

eBay auction: #252861537454

I didn't got for USB connectivity.  It works fine standalone.

[fishandchips]

I have not measured inductance before. I need your inputs. Is there a need to measure the inductance over time? Is the inductance constant for a specific motor or it changes over time during the motor's operation?

[metrologist]

I think you want to measure the phase lag of the voltage to current.


I found this article:

Why spend $ 60 on the IR-USB module . I was able to connect to the PC with just one phototransistor and USB-UART(TTL) converter ?nd the software is available for free.
You can use any Chinese USB-TTL converter, but I used the module with CP2102.
Phototransistor L-53P3C.

  Nice one!

@VA

Well done! Great Job!   

Please, can you share the 3D model for the small enclosure you've done?

Thank you!!!

[VA]

@natman69
Yes of course. In the description for the video. There are links to STL model and software.

FWIW, the original question was: Is the DE-5000 software useful?

As the only person so far we're sure can answer, is it? Does it do anything the handheld doesn't? Does it display data more quickly, or in a better format? Does it do graphs or anything?

[natman69]

@VA

Thank you!!!

@technogeeky
I will try to answer.
1.The transmission delay on the PC is very small. One of the advantages of software, is the ability to display on a large screen.
2.The device has the capability of a dual display, But to display different information from the second display, you need to switch, The software receives and displays all the data at once.
3.Some data received by the software have additional resolution that is not displayed on the screen
For some people, these features can be useful, but I believe that it is not worth the money that ask for the original kit.
But if you make the adapter yourself (it cost me $ 2) Then it's worth it.

"Does it do graphs or anything?"
Yes. Here is an example graphic, NTC thermistor.

Sorry to restart an old topic but I cannot make it work.

- I've used this UART-USB:
https://www.ebay.com/itm/CP2102-MICRO-USB-to-UART-TTL-Module-6Pin-Serial-Converter-STC-Replace-FT232/331768750751?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

- I installed the Silicon Labs CP210x USB to UART Bridge driver, Win7, 64bits:
https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers
Had to turn off the option "Allow the computer to turn of this device to save power". Otherwise the ON LED turned off after a few seconds.

- I've used a L53P3C phototransistor (Collector to RXI and Emmiter to GND):
https://www.ebay.com/itm/Infra-Red-Remote-Phototransistor-Receiver-L-53P3C/202033205149?ssPageName=STRK%3AMEBIDX%3AIT&var=502031433039&_trksid=p2057872.m2749.l2649

- Installed the original DE-6000 software (valid for the DE-5000) from IETLABS:
https://www.ietlabs.com/de6000-lcr-meter.html

- I made a 3D printed plastic case as per the files in the russian youtube.

Everything seemed OK but the SW cannot read anything from the DE-5000 and, yes, I clicked the PC key...

More:

- I've attached a scope to the L53P3C and got a pulse every 500ms.

- I've pointed a digital camera towards the DE-5000 infrared emmiter diode and clearly saw a light pulse every half second in the camera screen.


Any ideas?

Hi, maybe you have a fake L53P3C phototransistor, or it solder wrong?
Also maybe CP2102 damaged, or Pull-UP Resistor on RXI does not work or have cold join.
If hardware is ok, try open COM port in Putty, see if there is any data.
In software choose the right com port.

Don't think so: I get pulses from it when I probe it with a scope.
I've used two of them: Collector to RXI and Emmiter to GND. Collector is the short lead and "flat" side of the capsule "rim".

Also maybe CP2102 damaged, or Pull-UP Resistor on RXI does not work or have cold join.

When I connect it to the computer it instantly starts the COM port in the device driver and apparently works well. Regarding the cold joint, RXI reads 4.2V  to ground... yes, this is one of those CP2102 boards that read 4.2V in the 3.3V port 

If hardware is ok, try open COM port in Putty, see if there is any data.

Sorry but I do not know how to do that 

In software choose the right com port.

Already done: COM4 in my case, no "autodetect"

Here is a software that works for me: https://goo.gl/ahJzZo

I'll give it a try but it is apparently the same SW...

Sorry, mate! 

Thanks a lot for your answers!

My DIY of this interface. Works on WinXP.

[JDubU]

I don't have a 3D printer so I made a simpler version.
The photo transistor is supported by a neoprene foam pad identical to the one that comes with the DE-5000.
Photo transistor:  https://www.digikey.com/product-detail/en/kingbright/WP7113P3C/754-2137-ND/7318904

Needed to add a 470 ohm pull up resistor on the Rx input of the serial to USB converter (FTDI based in this case but my CP2102 also needed one).  The photo transistor acts as a pull down.
Works great.  Some photos are below.

[Calambres]

Thanks all for your answers. I'll try with the 470R pull-up resistor.

[Calambres]

Still not working!   

- I established connection with the UART via PUTTY: linked TX and RX and got readings. Put LOCAL ECHO ON and got double keystrokes, as expected...
- I added a 470R pullup resistor between 3.3V and RX
- Removed the DE-6000 SW and installed the DE-5000 SW from VA's link. I would swear they're the same!
- Still get readings with the scope when measuring across the phototransistor.

... but no reading in the SW screen. Dunno what else to do! 

[Calambres]

Tried with another computer, this time WIN-XP. Still no success
