I replaced my cell a couple of weeks ago with a brand new one. Right after I installed it, the K-1766 test (also a brand new replacement) indicated 2200 ppm, which was identical to the reading I was getting from the SWG. I shut it off, added 100 lbs. of salt, and 24 hours after turning my SWG back on, it was reading 2700. The Taylor test was giving me a readout of 3200 ppm, which is exactly where I'd expect it to be based on the salt added. I tried the recalibration method that both Hayward and people on this forum have recommended: turn off SWG, turn back on, press diagnostic button 5 times, wait for 'click' and then momentarily push switch up to superchlorinate when the instant reading lands close to the expected value. The highest choice it ever gave me was 2700, so that's where I calibrated it. It has continued to give me a reading of 2700 since, until last night when it gave me a reading of 2600. A subsequent K-1766 test - performed three times - this morning yielded the same 3200 ppm. This deviation (and the SWG behavior) is considerably different than when the old cell was installed, even as it was nearing end-of-life. I know it's generally accepted that the margin of error is about +/- 400 ppm for both the SWG and the Taylor test, and so with compounding error, the difference could very well be within the margin of error, but it still feels "off" to me. What's especially troublesome is that the SWG is showing declining salinity despite zero water replacement in two weeks.
So...is there cause for concern? Or should I just feed it the additional salt that it wants to keep it happy and not worry about it?
***EDIT to add additional info for reference:
Water temp: 74
Product name set to AL-6
