Default checking blazer temp with meter on temp sending unit

Hello I'm new here and want to start by saying hello.So I have a faulty gauge cluster I have replaced both my temp sensors,I cant get a accurate reading on my cluster so I want to use my mutimeter and check resistance or voltage off the sending unit itself that goes to gauge cluster to get its values and see what that translates into temperature.It seems like everytime I look up the values its for the sensor that goes to the computer and not the sending unit on the driver side of the block.Now today I drove the car for 15 min and let sit at idle for 5 mins and checked the voltage and resistance heres what my meter says.


I couldn't get a reading from anything other then 200mv as it seems to be reading under a volt.


volts


200mv - 08.0


-----------------------------------------------------------------------------
ohms


2000k


012
-----------------------------------------------------------------------------
200k


00.7
-------------------------------------------------------------------------------
20k


.36


-------------------------------------------------------------------------------
2k


482

The "OHMS" column on the right, are the resistance values at the sensor, with the connector unplugged.
