2410 Read Voltage loads UUT output

Hello,

I inherited some LabVIEW SW that Reads the Voltage on a UUT.
When the 2410 is switched in (Relays) the UUT output is loaded down.

I put a 1.5 Battery in series with a another external Current meter, during measurement it draws 200mA.

I have attached an image of the VI.

What I am not sure about is what was in the original meter's *RCL 0.
I have another post on that topic.

Thank you, Jeff

Probably has something to do with output off mode, eg, what happens when SMU blue light is off. Is this the condition underwhich you see the UUT loading?
