PXIe-4139 Output on-board relay control

[pgo]

Hello,

About PXIe-4139 SMU:

There are two options to Switch Off Output (see attached screenshot):

  Option 1 -  by property node "Output Connected" 

  Option 2 -  by "niDCPower Configure Output Enabled.vi"

According to https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z0000019OQ0SAM&l=en-BG, Option 1 disconnect (switch off) on-board relay.

What about Option 2 ???  Does "niDCPower Configure Output Enabled.vi" disconnects on-board relay as well ???

Hi @pgo, 

Setting the Output Enabled property to “False” sets:

Output mode = Voltage

Voltage setpoint =  0V

Current limit = %2 of the current range.

It does not disconnect the output relay.
