The SP1 settings determine the operating parameters for Relay A; while
SP2 settings define the operating parameters for Relay B. Since these

measurement mode (pH & ORP). However, when you switch
measurement modes, the relay operating parameters will be reset
automatically to their default values for that particular measurement
mode.
