Not a legitimate way to test it.
Normally, if you fire up the engine and watch your gauge until it is at operating temperature. Then go stand at the front of your rig.
If the clutch is operating correctly, you will hear it change from a mild sound to a strong roar (the radiator heat made it engage) After the roaring fan cools the radiator it will return to that mild sound. After a bit, the radiator will get hot again and again it will roar. This will happen over and over.
