Bolt Tension Wheatstone Bridge Connection

[NINOOB]

Hello I am using strain bolts with a full bridge set-up (one bolt per  NI9949 and 4 NI9949 into NI9237 module).  I was unsure of the correct wiring for this to work correctly.  I have attached a diagram of how it should be hooked up and how I have it hooked up.  Please indicate if this is a correct set-up.  If not then please advise.  Also, what setting do I need to have to get a reading?

Thanks so much in advance and please excuse my lack of knowledge on this.

Should I be using a Quarter bridge set-up instead?  If so do I need to purchase NI 9945 or can I get the NI9949 modules to work he same?

You're doing everything correctly from what I can tell.  Here's a pretty helpful document to verify this information as well as provide you with more insight to the different bridge configurations:  Connecting Strain Gauges and Shunt Resistors to the 9237.  A second document, Strain Gauge Configuration Types, should help you decide which bridge configuration you need to use.  The 9949 is simply a break out box for the 9237, and this can be used for full bridge or half bridge configurations. 

Hope this helps!
