(*1): Membrane check can be enabled when galvanic sensor is selected and cannot be used unless the
floating ball holder, PB350G or PB360G, is used.
(*2): The instrument will not perform salinity compensation simply by setting the salinity compensation to
“1” (enabled) in Code 04, but requires the NaCl concentration. For measurement in consideration of
the salinity of a sample, first, manually calibrate with values corrected for salinity and enter the NaCl
concentration in Code 04. (See Section 6-4, “Calibration method using manual calibration method”)
(*3): Set 60 nA for the DO70G optical dissolved oxygen sensor.
