Testing a MAP Sensor

I'm putting a turbo in my gen3. I just aquired a 3sgte MAP sensor, but I don't know if it still works. Does anyone know how to test a MAP sensor?

To test the MAP sensor properly you would need a special vacuum pump with a
pressure meter on, apply specified vacuum and and measure the output of the MAP sensor
with a multi-meter, and compare with the table bellow. Having that said MAP sensors rarely
brake down or go bad so even if you don't have the tools to test it, it most likely works as
it should.
