1. Mode can be off, Do, AgO2DO or manual. DO mode can be selected when
DO2 loop is in PID mode. AgO2DO mode can be selected when DO2 loop
is in PID mode and agitation is in DO mode.
2. P (Proportional) I (Integral) value can be selected by the operator. Move
cursor to O2, press code "9XXXX", then P I value can be changed.*
* NOTE: P I values have been set in the factory before shipping.
Under normal conditions, it is not necessary to reset
