DC Bias on 4276a initiated by Labview

Question

I am working with the 4276A LCZ Meter, and I have downloaded and installed the driver for it. However, I open up the example VI and it seems to work except it puts out the error "ERROR 1300" in Labview and on the realy instrument it displays "ER 13".
I talked to my colleagues about this and it seems that there is some assumptions made by labview over the instrument. In the 4276a manual (Section III, 3-14) (page 56 in pdf), it says that this error occurs if internal DC bias voltage was set via the HP-IP but instrument is not equiped with Option 1 (Which is a DC Bias Supply), or it occurs if the comparator enable code (E1) was sent via the HP-IB, but the instrument is not equipped with option 2 (which is a comparator/handler interface).
Well, this 4276a is not equipped with either option. The switch on the instrument that turns on the DC Bias is off. However, as you can see from the picture showing my error, there is a DC bias in the VI itself.
So I am wondering, how would I go about turning off the DC bias or stopping LabView from turning it on? I have looked through the subVIs that make up this example.VI and there is no code that inputs the string "E1" for the enable code, so I don't believe the error occurs because of the Option 2.
I have added the block diagram for the example.VI. In addition, I added the subVi (ConfigTestSignal.VI) which contains the DC Bias input.
Let me know what you guys think. THANK YOU!

Hello Erny123,
I've not read the manual, but I would guess that BI is a string that indicates a bias configuration, and EN indicates the end of the command.  "%.1f" is a format specifier that inserts a floating-point decimal value with one digit of precision (refer to that link for the syntax requirements when using the Format Value function). Just above that you can see that a similar format function is used to insert the test frequency into the command string using FR rather than BI, and a slightly different numeric format.
The example you're using hasn't been written using the standard LabVIEW style, so it may be a little hard to track what inputs and outputs go where.  Try clicking the Clean Up Diagram icon in the example's block diagram to re-order things in a more logical left-to-right fashion. 
What this VI is doing is composing a string of commands to send to the instrument- you'll need to refer to the manual to see what the format requirements are, but I would guess that you can just delete the second format value function and wire the output of the first through to the send message VI. 
I wouldn't say that you need to start from scratch every time, but yes, you'll need to make some modifications to this example to get it to work for you.  I'd strongly recommend that you go through one or more of the LabVIEW tutorials available online, it'll save you a lot of time in the long run.
