Aquarite won't scroll down during recalibration.

[RebeccaP]

We installed a new salt cell last weekend. Hayward T-9. (Replaced another Hayward T-9) I need to recalibrate because it's showing the salt level is 3800 when it is actually 3100. (3100 is in line with what was reading before we changed the cell and i just had the salt level tested yesterday, so I know the 3800 displayed is incorrect.) When I go through the steps to recalibrate, I am able to get to the salt level but the number won't drop below 3700. It does drop, but starts around 4000 (varies as i've tried multiple times) and only drops a couple thousand before stopping.
It is an Aquarite 900.
Diagnostic readings are...
79
25.9
4.63
72
-3500
AL-0
r 1.59
t - 9

Any thoughts on why it won't recalibrate?
(I will also mention the chlorine is only at .5 and I'm assuming this is because the salt reading is too high to make chlorine.)

Welcome to TFP.

The Aquarite does not have a calibration. And it does not have a salt sensor.

The Aquarite takes its instant salinity calculation and replace the average salinity that it displays. That is what you call recalibration. In the diagnostics you posted the Aquarite calculates the instant salinity to be 3500ppm.

Your Aquarite is fine and as the cell ages its salinity calculation will drop below the actual salt level.

You don't really know which one is correct.

Salinity testing is not super accurate and unless you have many different readings from reliable tests, you cannot be sure what the actual number is.

Even if a test is ideally +/- 200 ppm, that does not mean that the result that you get is +/- 200 ppm.

In any case, it does not matter as long as the High Salt light is not coming on.

The test at the pool shop we use has always been pretty accurate in the past (or at least matched our Aquarite) but it sounds like you are saying that so long as the "High Salt" light isn't on, chlorine should still be produced. Thanks! Appreciate it.

I read the info "further reading" you provided. Good info. Sounds like it could be reading high because it's new. I'm not sure why I was able to find videos on recalibrating the Aquarite if it's not possible to recalibrate, so I find that a bit confusing. But so long as the high reading isn't preventing it from producing chlorine, I guess there's no harm. Thanks!

Correct.

Many folks do not really understand how the system works. Lots of misinformation on YouTube.

Yes!

People overestimate the accuracy of salinity tests.

Unless you have 5 reliable tests with good agreement, you do not really know what the salinity is.

The Aquarite is just as likely to be correct as any test you do.

In any case, as long as the "High Salt" light is not on, the salinity is not too high.

the salt level is 3800 when it is actually 3100.

The instant salinity says 3,500 ppm.

3,100 and 3,500 are close enough and the actual salinity is likely to be somewhere in the middle.

The average is 3,300 ppm.
