How to connect dwyer SERIES 629 Differential Pressure Transmitter to the 9219 DAQ and read the signal?

Here is my sensor 
Pressure Sensor

Here is the DAQ datasheet:

NI DAQ 9219

Here are my problems/Questions:

First of all I do not know what is LO and HI exactly in the 9219 DAQ device. 

Secondly I do not know which pin I should connect the sensor signal wire to DAQ. Pin 4 or pin 5 ? The sensor has three pins and I assume I should connect the two other wires to the voltage power supply. 
Thirdly how to calibrate the sensor. In labview should I choose voltage in the wizard?

I am fairly new in this DAQ and I need your help. 

Thank you
