Yokogawa WT210 data aqusition

[Mully911]

Hello,

I am newer to LV and have just perchased the latest version and would like to log voltage, current and watts using a Yokogawa WT210 power meter.

I have:

1) purchased LabView and am waiting for it.

2) Yokogawa WT210 power meter with GPIB output option

3) GPIB-USB -HS NI-488.2 for Windows cable

4) Windows XP computer

I have read and searched but may not have been in the correct area..???

I am asking someone to help me with a .vi that will write and read data from this WT210 so I can save the data to an Excel file.

Thanks

Mully

Go to Tools>Instrumentation>Find Instrument Drivers and search for WT210. You can also go to the Instrument Driver Network and start your search or follow the links to learn what an instrument driver is and how to use one.

Ok, so after I receive LV I can download a driver...Whats next?

[Dennis_Knutson]

Learn how to use LabVIEW and learn how to use the driver. The driver will come with an example of how to use different functions that are in driver. LabVIEW will also come with numerous examples. Many deal with file I/O. If you bought the report gneration toolkit, you can write directly to excel. If you didn't, functions exist to write to text files that Excel can import or you can use ActiveX.

Hello to all

I'm using YOKOGAWA WT210, I found Drivers of the instruments and I'm learning how to use it.

I have used this instrument for long time without remote control, and now I'm trying to built a power supply automatic testing system.

I use to measure the input active power of an AC / DC converter averaging the instantaneous input power (integral of the input energy divided by the time).

I able to perform this kind of measurement with Local control, but I'm not able to do the same through GPIB control. 

Is there anyone that can help me with this Topic?

Regards

Davide

I would recommend starting with some of the GPIB examples to learn how to communicate over GPIB. There are also numerous online resources at ni.com including tutorials and knowledge base articles. What specifically are the problems you are running into?

Hi thank you for your reply.

The main problem is that I can't find the GPIB command I need to read the result of my measurament in User Manual of YOKOGAWA WT210. Even if I have downloaded the instrument drivers and I'm able to set the parameter for integration (mainly the TIME of integration, start measurament) I'm not able to read the final result neither on the instrument diplay neihter through GPIB control. 

I'able to perform this measurament and read the result on the instrument display if I use local control.

Thank you in advance for any help.

Regards

Hi, we have 3 or 4 Wt210's in our lab as well as WT110, and Wt200 models. Have you tried the free software available from Yokogawa? We have here and although not perfect it is useful and can be considered off the shelf verified (which is a big deal in this lab). It is available from the same link as where you would get the labview drivers, and is called WT Viewer. I also just noticed a free power consumption software download. It can take a long time to develop, debug, and verify new software, so if a useable version already exists, then why not give it a try? Of course if you are budgeted and have the time to develop from scratch then by all means enjoy the experience! Either way I hope it works out for you.

Hello,

I have a WT210 and a WT230 in my lab. I have been successful in using the example programs to keep track of the real time current, power and voltage. However now I need a running summation of the total power consumed. Judging by what it says in the manual I need to use an integration code. However the one they provide seems to run forever even if you enter a time. Does someone have a vi that they could share that totalizes the power consumption and displays the value and or could help me write this code. Oh, and I would like to first get the WT210 to work and then I would think I should be able to use the 230 relatively easily after that.

Thanks!

Pete
