Yokogawa WT3000 Measure Element

[Shakes84]

Hi,

Let me start off by saying I am a novice with LabView.

I am using both the WT3000 in a test setup to measure specific input/output characteristics of a EUT. I am attempting automate this step by using Labview, with the 3000 connected via GPIB (NIMAx) to my computer.

I have written the program below for the Yokos to first make the following measurements using Elements and 2 to measure input & output of the EUT:

Element 1:

• Input Voltage (U)
• Input Current (I)
• Input Power (P)
• Input Freq (FU)
• Input Harmonics Distortion (ITHD)

Element2:

• Output Voltage (U)
• Output Current (I)
• Output Power (P)

Then in the last frame get all values from WT3000 and display.

When I run my program below I get readings just for my Input voltage and Current on Element #1

Not sure where I am going wrong…

Step1

Command for measurements on Element#1 per above:

Step 2

Command for measurements on Element#2 per above:

Step 3

Query all measurements made on Element#1 & Element#2:

Any help would be greatly appreciated.

Thank You

Shakes84 - I suggest that you download the free library for the WT3000 from here.  http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=F1AD0986274A22AFE0340003BA230E...

What version of LV are you using?

I don't have a WT3000 here but I have several 500s and 1800s which have the same basic command structure.  This should work if you download the WT3000 library from the Instrument Driver Network
