desired parameters. Consider recalibrating the system after the initial 24 hours as the sensor
acclimate to the system. If the sanitizer level is too low or high, adjust the feed level up or
down in small increments, (for example 10mv to 25 mv increments) to lock in the desired
sanitizer level. However, prior to adjusting the ORP level, check pH level and
adjust/recalibrate the pH if necessary.
