Aqua Rite salt level drifts lower

[YumaDavid]

Moved from here.
I have a 3 month old Tcell 940 Hayward and a NatureSoft Salt Panel

My problem is that I can not keep the salt level at 3700, which is where it is at. Both Leslie and my salt test are within a few hundred, Leslie says 4000 and my testing shows 3700

My problem is it will drift from 3900 to 2300 and stop generating

I set the reading to -3900 by shifting to T9 and then back to T15 after it is set, I cannot get the instant read over 2500 in The T 15 setting

Once set I do go back to T 15, with my 3 month old Tcell 940

Any ideas

For AquaRite, move the switch from auto to off and check all of the readings.

Move the switch back to auto and recheck the readings.

Move the switch to off for a minute and then back to auto and recheck the readings.

Report all readings.

What are the first seven characters of the cell and box serial numbers?

You need to be really sure about the actual salinity reading.

You need to use a K-1766 salt test kit or a calibrated meter.

K-1766 Taylor Salt Test

Are you sure that the cell is a 940?
