The analyzer output is always proportional to measured pH or conductivity. To prevent unwanted alarms and improper operation of control systems or dosing pumps, place the analyzer in hold before removing the sensor for calibration and maintenance. Be sure to remove the analyzer from hold once Hold calibration is complete. During hold, both outputs remain at the last value. Once in hold, the analyzer remains there indefinitely. While in hold, the screen
shown to the left appears periodically.
