I have a Jazcuzi SWG. It has five output positions on it that are indicated by the number of lit lights light on the display. My CYA in 80. I bumped up my SWG output to maximum (5) about 2 weeks ago prior to a large planned pool party. By the time I remembered to turn it down my CL was 11. I been trying to get my CL back down to a reading of 5 by lowerering the setting down to 3 for a few days then 2 and now 1. I still am getting a CL reading of 10. I am beginning to think somehow the setting is still at a 5 output even though the lights on it say 1. How can I verify that the SWG has a setting problem short of turning it off for a few days and see if the CL reading goes down. How does the output adjustments change the chlorine output of the generator? Is it done by applying a different voltage to the conversation plates. If so can I measure the voltage to see if it changes when I change the setting?
