I'm trying my best to recalibrate my pureline salt cell and i cant seem to figure out how to do it

Im following the attached instructions and when i follow step 1, i cant seem to hear the click after 5-10 seconds.

then in step 2 the number is not negative and when i toggle the switch from Super Chlorinate to Auto it changes  from PPM to decimal (example from 2900 to 2.9) ??

Please help
