Default How to test sending unit

I am trying to test a low pressure sending unit that has a range from 240 (0 psi)ohms to 33(15psi). At 0 pressure it should read 240 but with the unit out of the car and on the table my ohm meter is not getting a consistant reading. I put one terminal on the stud and one on the base were the 1/8 pipe threads are. What do I need to do to test the sending unit? does it need some sort of 12v hook up?
