Erratic readings from an Aquarite salt board could be irritating, however there are some things you are able to do to repair the issue. First, test the probe to verify it’s clear and freed from particles. If the probe is soiled, it will be unable to precisely measure the salt stage within the water.
Subsequent, test the calibration of the salt board. The calibration can drift over time, so you will need to recalibrate the board repeatedly. To recalibrate the board, you’ll need a calibration resolution. Upon getting the calibration resolution, comply with the directions on the board to recalibrate it.
