I thought that you'd need some type of measuring equipment to do a compression check ?

Yes, A compression tester. However to use the compression tester you need to crank the engine, you don't want fuel and spark when you are cranking it just to test compression.
Everyone above is describing ways to cut fuel and spark.

yeah it's a pressure gauge, thats about it.
you stick it in the spark plug hole and you crank the engine...this measures how much compression you are making in each cylinder.
Incorrect. Not with a wasted spark ignition system unless you ground the plug wire you removed. If you don't you have 30,000volts that has to go somewhere and it can ark inside the coil internally and blow an ignitor.
