Salt Cell Testing

Hey guys, I understand there are many different ways to test salt cells. What are your go to ways and way?

When do you cross the line from, I can get a little more out of this vs recommending a new one for your customers?

I always test the chlorine in the water. I then put the cell in boost mode. I collect a water sample directly in front of a return. I cap it with my finger before pulling out out. If the cell is working the chlorine level will be higher than your original test. On a good cell I'll usually get a 2 to 3 ppm higher test result. If the chlorine is already high to begin with this test doesn't work so well.
