Possible to Recalibrate a Goldline (Hayward) Aqua Logic Salt Reading?

[CC57]

So recently picked up the TF 100 and accompanying salt test kit.

The salt test kit has consistently provided readings much higher than what my board shows.
I've taken salt reading of 5200, 5800, 4800, 4000, where the Aqua Logic has been displaying in the low 3000s.

I also, in hopes to validate my salt test readings, bought some salt test strips. (My plan is to settle on using the test kit, but for now I wanted a 3rd set of data to help assure me of what I was seeing. )

So today:
TFP test kit: 4,000 ppm.
Test strip: 3,700 ppm
Aqua board: 2,600 ppm

I've been looking around the net for advice on how to recalibrate the system (will try Hayward during their next set of business hours) but have yet to find how to recalibrate the board.

If there is here anyone on here than knows how and is willing to give fill me in, I would sincerely appreciate it.

Thanks all

Let's start with agreeing your actual salt level is 4,000 if you used the test kit drop test.

The Aquaboard does NOT measure salt levels. It has no salinity sensor. It just calculates what the salt level would be on a new cell based on the volts and amps the cell uses.

There is no way to "calibrate" the salt level. The Aquaboard will report what itc alculates.

The AquaRite uses the performance of the cell to determine salinity. For each cell (T-3, T-5, T-9 OR T-15), Hayward knows the performance of a properly functioning cell at each temperature and salinity combination. The higher the salinity and/or water temperature, the higher the performance (chlorine output).

To get the performance of the cell, divide the instant salinity by the actual salinity. If the ratio is less than 75%, it's time for a new cell. For example, 2,600 (instant salinity) ÷ 4,000 (measured salinity with a test kit)=65%. Check the cell and clean it if necessary. If that doesn't work, it's time for a new cell.

Once you replace the cell you need to lower your salt level by drining about 20% of your water and get it down around 3,000. High salt levels are bad for Hayward boards and burn them out. It if better for board longevity to keep the salt level at the lo end of the range.

You should always test the salt level before adding salt and NEVER rely on the Hayward salt display.

Thank you ajw.

I ran a test with my Salt Cell supplier. They feel like the cell has malfunctioned. A replacement is on its way.

Hopefully once the new cell has been installed the readings will be more in line with what my vial test have shown.
