Pierre,
Welcome to ECN!
I've only done it a few times and it was at the request of a local AHJ to verify bonding either on pools that never had an inspection, or were over 10 yrs old and he had been asked to re-certify.
I didn't really have any direction on this as to best way or readings to look for. He wanted me to confirm low resistance readings between bonding points and that was the easiest way I could think of.
I don't recall the specific readings, but I think one ohm (or less) sounds familiar. On one I got good readings on the diving platform, but the ladder cups were no good so I had to 'fail' it. On another the Slide (which was installed after the pool) showed high resistance and I had to fail that too.
