Yokogawa WT3000 Measure Element

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
